Introduction
The A8266-096-Clock is a 0.96-inch OLED network desktop clock built around the ESP8266. It retrieves the time automatically from an NTP server over Wi-Fi, supports world time zones and daylight saving time, and can show the current weather, a 3-day forecast, device information and alarm reminders on the OLED. The unit is powered through USB-C and provides a built-in web configuration page, so no extra app is required - a phone or a computer is enough to complete network provisioning and parameter setup.

FAQ
Q1:OLED stays dark
Check the USB-C power supply; check in the serial log whether the I2C scan found 0x3C.
Q2:Cannot connect to Wi-Fi
Confirm that the network is 2.4 GHz and the password is correct; retry closer to the router.
Q3:Time shows waiting for synchronisation
Make sure the network allows ntp.aliyun.com / pool.ntp.org
Q4:Weather shows WEATHER DATA ERR
Check the network; the device retries automatically later
