Align the E-paper 24P Shield pin headers with the matching sockets of the Arduino mainboard and, after confirming the orientation, press straight down.

			2. According to the selected e-paper screen, choose P2 jumper value 2.2 Ω or 0.47 Ω.

			3. Insert the e-paper's FPC 24P flat cable with its metal contacts facing up into the P1 slot, then press the connector latch firmly closed.

			4. Supply power via USB or an external source to the Arduino mainboard; the screen automatically enters the refresh-standby state.

-|highlights=* SPI interface saves MCU pins.
+|highlights=1.OLED 30P Shield is a display expansion board (Shield) from OLIGHKER that complies with the Arduino interface standard. It carries an onboard FPC 30P connector for directly attaching OLED displays with an FPC 30P interface, and works with any main board that supports the standard Arduino interface.
-* Supports partial refresh and common graphics drawing workflows.
-* Interface, parameters, and FAQ are all maintainable via backend.

-: Check reset, chip select, data/command pins, and initialization model.
+A1: First check the FFC ribbon orientation — the gold fingers must face up when inserted into the FPC connector; a reversed ribbon will keep the display from lighting up. Also make sure the locking cap is pressed down firmly. If the ribbon is fine, the most likely cause is an I2C address mismatch: the address differs between displays (commonly 0x78). Try a different address in your sketch, and check whether SDA/SCL are swapped.
-; What if the image has noise?
-: Lower the SPI clock and shorten the connection wires.

It follows the Arduino UNO board layout and pin-header arrangement,integrates a Micro-USB serial chip and a 5V/1A switching power supply, and lets you write and upload programs directly with the Arduino IDE — a cost-effective choice for getting started with IoT development.
	* Suitable for driver verification, ~~teaching~~, and prototyping.
	* Page does not correspond to any specific brand or commercial model.		2.The board ships with its hardware and software resources fully open, allowing secondary development. You can use it directly as a Wi-Fi-enabled Arduino board, or build on it by trimming the low-level firmware and expanding peripheral interfaces. It suits IoT education, smart-home prototyping, and wireless data acquisition scenarios.

	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.		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).
