Starter ESPHome config
Built from the pinout above. Keys and the Wi-Fi password come from secrets.yaml in ESPHome. Check the pins against your hardware revision before flashing: one model can ship with different boards.

How to flash
- Most devices are flashed over UART: a 3.3 V USB-TTL adapter to RX, TX, GND and 3V3, holding GPIO0 to ground at power-on (ESP8266/ESP32). Mains power disconnected.
- Beken (BK72xx) and Realtek chips are flashed with ltchiptool, or with cloudcutter without opening the case if the firmware allows it.
- Details and board photos: the device page in the ESPHome database.
