|intro=Arduino
|highlights=1.OLED 24P Shield is an OLED display shield compatible with the standard Arduino interface. Its onboard 24P FPC connector (P2) accepts OLED displays with a 24-pin FPC interface, while the header pins on the underside match the universal Arduino standard interface, so it plugs straight into any board that supports the Arduino interface and adds OLED display capability to any project.

2.The shield communicates over I2C: only two signal lines, SDA and SCL, are needed to drive the display, leaving all other I/O free for the controller. With the onboard address-selection jumper and power circuitry, it is ready to use once installed, with no extra wiring.

|faq==== '''<span style="color: rgb(52, 176, 176);">1.Display insertion:</span>''' ===
Make sure the FPC of the OLED is inserted in the correct direction, with the metal contacts facing the connector contacts; reversing it may leave the display dark or damage it.

=== '''<span style="color: rgb(52, 176, 176);">2.Supply voltage:</span>''' ===
The shield is powered from the 3V3 pin of the main board; do not connect it to a 5V power pin, as this exceeds the OLED operating voltage.

=== '''<span style="color: rgb(52, 176, 176);">3. I2C address:</span>''' ===
When several I2C devices share the bus and their addresses conflict, change the OLED address with the onboard address-selection jumper.

=== '''<span style="color: rgb(52, 176, 176);">4.Signal quality:</span>''' ===
Use pull-up resistors on the I2C bus, which most boards already include, and keep wiring as short as possible to avoid interference.

=== '''<span style="color: rgb(52, 176, 176);">5.ESD and handling:</span>''' ===
Disconnect power from the main board before inserting or removing the shield, to prevent damage from hot-plugging.

{{ProductInfo
|title=1.54 inch 4-color E-paper mini photo board
|model=1.54 inch Photo Board(4C)
|status=Published
|module=ESP32
|image1=1.54 800-600-1-1.jpg
|image2=1.54 800-600-2.jpg
|intro=Photo, ESP32, JD79660, SPI
|highlights==== <span style="color: rgb(52, 176, 176);">1. Product Overview</span> ===
The 1.54" BWRY Mini Photo Album is a low-power frame built around the ESP32-C3 Super Mini controller and a 1.54" BWRY four-color e-paper display (driver IC: JD79660). It needs no internet or mobile app; just connect to the hotspot it broadcasts and open 192.168.4.1 in any browser to upload photos, browse the album and configure the slideshow. The device has no physical buttons or TF card slot, so all interaction is done in the browser;photos are stored in the on-board LittleFS file system and survive a power loss. The screen supports black / white / red / yellow four-color display; combined with the browser-side Floyd-Steinberg dithering, it renders color photos in fine detail as a four-color e-paper image.

=== <span style="color: rgb(52, 176, 176);">2. Key Features</span> ===
 1.54" BWRY four-color e-paper (200 × 200,2bpp, 10,000 bytes per frame).

 WiFi AP direct mode: SSID = ePaperAlbum, password 88888888,IP 192.168.4.1.

 Four-color dithering is done in the browser (no server involved); each image uses only ~10 KB of data.

 LittleFS stores photos; NVS saves the current display and slideshow settings.

 Supports gallery list, single-image switching, single/all deletion, and slideshow auto-play.

 Supports EN / RU bilingual Web UI (English / Russian Web).

 HTTP server starts before the boot refresh and keeps responding throughout it, so it isaccessible as soon as you join the hotspot.

=== <span style="color: rgb(52, 176, 176);">3. Use Cases</span> ===
 Compact desktop photo frame: plug in and use, with no dependence on a router or cloud service.

 Gift / ornament: converts photos of family and friends into a four-color e-paper style display.

 Embedded / IoT learning reference: a complete ESP32 + WebServer + LittleFS practice.

|faq==== <span style="color: rgb(52, 176, 176);">Q: Cannot Connect / Can't Find the WiFi</span> ===
 Make sure the device has been powered on for over 5 seconds (the boot refresh takes
about 12 ~ 15 seconds, and the hotspot has already begun broadcasting).

 Pull down to refresh the WiFi list on your phone to see whether ePaperAlbum can be found.

 If the hotspot disappears and reappears after a few minutes, this is normal (the device keeps it alive with an internal heartbeat).

 In an extreme case: unplug the power, wait 10 seconds, then power back on; the device restarts the AP automatically.

=== <span style="color: rgb(52, 176, 176);">Q: Screen Doesn't Change After Upload</span> ===
 First make sure the Web page status shows Sent and saved!, otherwise the upload did not succeed.

 Make sure the uploaded file size is exactly 10,000 bytes (after dithering the browser shows "Preview ready"; it sends a fixed length).

 If it stays on "Sending (refresh ~15s)..." for over 30 seconds, try re-plugging the USB.

=== <span style="color: rgb(52, 176, 176);">Q: Switch / Delete Does Not Respond</span> ===
 The browser retries automatically 3 times (every 1.5 seconds); it usually recovers within 5 seconds.

 If there is no response for a long time, the AP may be temporarily unreachable

=== <span style="color: rgb(52, 176, 176);">Q: Ghosting / Garbled Screen</span> ===
 Occasional brief ghosting between different images is a normal physical property of epaper and isnot a fault.

 If it has not recovered within 1 minute or the ghosting is severe, power the device off and on to reset.

=== <span style="color: rgb(52, 176, 176);">Q: Upload Failure (HTTP 400 / 500)</span> ===
 HTTP 400 size mismatch — the uploaded byte count is not 10,000; do not upload manually outside the browser.

 HTTP 500 — LittleFS is out of space; delete some photos first.

|hardware==== <span style="color: rgb(52, 176, 176);">1.1 Connect Power</span> ===
Use a standard USB-C data cable to connect the board to a computer or charger. On power-up the screen shows the 4-color hint image.

=== <span style="color: rgb(52, 176, 176);">1.2 Connect to the Board</span> ===
The board starts Wi-Fi in AP mode by default:

 SSID: ePaperDisplay

 Password: 88888888

After connecting a phone or computer to this hotspot, open the browser at <nowiki>http://192.168.4.1</nowiki> to enter the configuration page.

=== <span style="color: rgb(52, 176, 176);">1.3 Switch to STA Mode</span> ===
To make the board join your home router directly, fill in the SSID and password under the Settings card of the Web UI and save. The board reboots and joins the router in STA mode. Open the browser at the IP it obtained from the router to access it on your local network (recommended for advanced users).

=== <span style="color: rgb(52, 176, 176);">1.4 Upload Your First Photo</span> ===
(1). Open <nowiki>http://192.168.4.1</nowiki> (AP mode) or the board's LAN IP.

(2). In the Upload card click Choose File and pick a JPG / PNG image from your computer (recommended aspect ratio ≈ 4:3).

(3). The browser quantizes the image locally into a 400×300 4-color image (black / white / red / yellow) and shows a live preview.

(4). Click Upload; once upload finishes, the screen refreshes within ~21 seconds.

|faq==== <span style="color: rgb(52, 176, 176);">Q1:Screen shows nothing after flashing?</span> ===
Check that the FPC 24P cable is firmly seated and oriented correctly (typically metal side up); make sure the supply is stable (recommend a 5 V / 1 A or better USB-C source).

=== <span style="color: rgb(52, 176, 176);">Q2:Cannot find the USB-SERIAL CH340 port?</span> ===
Try a different data cable (some cheap cables only charge); install the CH340 driver manually under Windows; hold BOOT while powering on to force the ESP32 into download mode.

=== <span style="color: rgb(52, 176, 176);">Q3:Web page won't open (192.168.4.1 no response)?</span> ===
Confirm the phone / computer has joined the board's AP hotspot (SSID: ePaperDisplay).Some phones conflict with mobile data — temporarily disable mobile data, or wait a few seconds after connecting.

=== <span style="color: rgb(52, 176, 176);">Q4:Screen doesn't update after upload?</span> ===
A full E-Paper refresh takes ~21 s — that's normal. If nothing changes after 30 s, press RST to reboot.

(1). Open <nowiki>http://192.168.4.1</nowiki> (AP mode) or the board's LAN IP.

(2). In the Upload card click Choose File and pick a JPG / PNG image from your computer (recommended aspect ratio ≈ 4:3).

(3). The browser quantizes the image locally into a 400×300 4-color image (black / white / red / yellow) and shows a live preview.

(4). Click Upload; once upload finishes, the screen refreshes within ~21 seconds.

|faq==== <span style="color: rgb(52, 176, 176);">Q1:Screen shows nothing after flashing?</span> ===
Check that the FPC 24P cable is firmly seated and oriented correctly (typically metal side up); make sure the supply is stable (recommend a 5 V / 1 A or better USB-C source).

=== <span style="color: rgb(52, 176, 176);">Q2:Cannot find the USB-SERIAL CH340 port?</span> ===
Try a different data cable (some cheap cables only charge); install the CH340 driver manually under Windows; hold BOOT while powering on to force the ESP32 into download mode.

=== <span style="color: rgb(52, 176, 176);">Q3:Web page won't open (192.168.4.1 no response)?</span> ===
Confirm the phone / computer has joined the board's AP hotspot (SSID: ePaperDisplay).Some phones conflict with mobile data — temporarily disable mobile data, or wait a few seconds after connecting.

=== <span style="color: rgb(52, 176, 176);">Q4:Screen doesn't update after upload?</span> ===
A full E-Paper refresh takes ~21 s — that's normal. If nothing changes after 30 s, press RST to reboot.

|intro=Photo, ESP32, JD79660, SPI
|highlights==== <span style="color: rgb(52, 176, 176);">1. Product Overview</span> ===
The 1.54" BWRY Mini Photo Album is a low-power frame built around the ESP32-C3 Super Mini controller and a 1.54" BWRY four-color e-paper display (driver IC: JD79660). It needs no internet or mobile app; just connect to the hotspot it broadcasts and open 192.168.4.1 in any browser to upload photos, browse the album and configure the slideshow. The device has no physical buttons or TF card slot, so all interaction is done in the browser;photos are stored in the on-board LittleFS file system and survive a power loss. The screen supports black / white / red / yellow four-color display; combined with the browser-side Floyd-Steinberg dithering, it renders color photos in fine detail as a four-color e-paper image.

=== <span style="color: rgb(52, 176, 176);">2. Key Features</span> ===
 1.54" BWRY four-color e-paper (200 × 200,2bpp, 10,000 bytes per frame).

 WiFi AP direct mode: SSID = ePaperAlbum, password 88888888,IP 192.168.4.1.

 Four-color dithering is done in the browser (no server involved); each image uses only ~10 KB of data.

 LittleFS stores photos; NVS saves the current display and slideshow settings.

 Supports gallery list, single-image switching, single/all deletion, and slideshow auto-play.

 Supports EN / RU bilingual Web UI (English / Russian Web).

 HTTP server starts before the boot refresh and keeps responding throughout it, so it isaccessible as soon as you join the hotspot.

=== <span style="color: rgb(52, 176, 176);">3. Use Cases</span> ===
 Compact desktop photo frame: plug in and use, with no dependence on a router or cloud service.

 Gift / ornament: converts photos of family and friends into a four-color e-paper style display.

 Embedded / IoT learning reference: a complete ESP32 + WebServer + LittleFS practice.

|faq==== <span style="color: rgb(52, 176, 176);">Q: Cannot Connect / Can't Find the WiFi</span> ===
 Make sure the device has been powered on for over 5 seconds (the boot refresh takes
about 12 ~ 15 seconds, and the hotspot has already begun broadcasting).

 Pull down to refresh the WiFi list on your phone to see whether ePaperAlbum can be found.

 If the hotspot disappears and reappears after a few minutes, this is normal (the device keeps it alive with an internal heartbeat).

 In an extreme case: unplug the power, wait 10 seconds, then power back on; the device restarts the AP automatically.

=== <span style="color: rgb(52, 176, 176);">Q: Screen Doesn't Change After Upload</span> ===
 First make sure the Web page status shows Sent and saved!, otherwise the upload did not succeed.

 Make sure the uploaded file size is exactly 10,000 bytes (after dithering the browser shows "Preview ready"; it sends a fixed length).

 If it stays on "Sending (refresh ~15s)..." for over 30 seconds, try re-plugging the USB.

=== <span style="color: rgb(52, 176, 176);">Q: Switch / Delete Does Not Respond</span> ===
 The browser retries automatically 3 times (every 1.5 seconds); it usually recovers within 5 seconds.

 If there is no response for a long time, the AP may be temporarily unreachable

=== <span style="color: rgb(52, 176, 176);">Q: Ghosting / Garbled Screen</span> ===
 Occasional brief ghosting between different images is a normal physical property of epaper and isnot a fault.

 If it has not recovered within 1 minute or the ghosting is severe, power the device off and on to reset.

=== <span style="color: rgb(52, 176, 176);">Q: Upload Failure (HTTP 400 / 500)</span> ===
 HTTP 400 size mismatch — the uploaded byte count is not 10,000; do not upload manually outside the browser.

 HTTP 500 — LittleFS is out of space; delete some photos first.

=== '''<span style="color: rgb(52, 176, 176);">1. First Use and Wi-Fi Setup</span>''' ===
On power-up the device enters AP+STA concurrent mode: it starts the configuration hotspot DeskClock-XXXXXX and at the same time tries to connect to the last saved home Wi-Fi.

=== <span style="color: rgb(52, 176, 176);">1.1 '''Setting up Wi-Fi with a phone'''</span> ===
1. Open Wi-Fi settings on your phone and join the hotspot named DeskClock-XXXXXX; the password is fixed at 88888888.

2. If the phone reports that the hotspot has no internet, stay connected anyway; open <nowiki>http://192.168.4.1/</nowiki> in a browser (some phones pop the page up automatically).

3. After the page loads, choose or scan for a 2.4 GHz Wi-Fi network, enter its password and tap “Connect & continue”.

4. Once connected, the device immediately saves the verified credentials; continue configuring the time zone, alarm and weather city.

5. Tap “Save & restart” — all settings are written to Flash with read-back verification, and the device restarts automatically in about 2 seconds.

'''Note:''' The setup hotspot is available from power-on and never closes when the home Wi-Fi connects; its password is fixed at 88888888. When uploading a sketch, set Erase Flash in the Arduino IDE to “Only Sketch”, otherwise the saved Wi-Fi passwords will be erased.

=== '''<span style="color: rgb(52, 176, 176);">1.2 Development environment</span>''' ===
To modify or extend the firmware, select NodeMCU 1.0 (ESP-12E Module) in the Arduino IDE, set CPU Frequency to 160 MHz, set Erase Flash to Only Sketch, and install ESP8266 Core 3.0.1 together with the U8g2 library. The NeoPixel driver and the single-file ArduinoJson library are already bundled.

The device has not connected to an internet-enabled Wi-Fi or NTP is blocked; check that the router allows access to ntp.aliyun.com and pool.ntp.org.

=== <span style="color: rgb(52, 176, 176);">Q5:Weather does not update</span> ===
Make sure Wi-Fi is online and time sync has completed; the first weather request starts only after 60 seconds of stable connection; TLS errors can be found in the serial log.

=== <span style="color: rgb(52, 176, 176);">Q6:The alarm does not ring</span> ===
Check that the alarm is enabled and the time is set correctly; in weekdays-only mode it does not trigger on Saturday or Sunday.
