  • One AD inputs.
  • Micro USB inputs.
  • One programmable LED (D0).
  • Integrated 18650 battery charging and discharging system.
  • One switch controls whether the 18650 battery is powered or not.
  • OLED's SDA and SCL connect to the D1 pin and the D2 pin respectively.
  • The five buttons are controlled by FLATH, RSET, D5, D6, and D7 respectively.
  • The 5 Digital pins can configure the write/read/interrupt/pwm/I2C/one-wire supported separately.
  • Operation and NodeMCU consistent, adding a programmable LED, you can use GPIO16 to control, display 8266 running status and other functions. Integrated OLED and five button, more convenient for development.
  • The design concept originates from the open source project NodeMCU, and the development board integrates 18650 charging and discharging systems with charging and discharging protection. At the same time, a OLED and five directional buttons are integrated to facilitate the development.

It would be very helpful to know what the model of the display is. I have been trying to set up one of these in ESPHome using the ssd1306 module but it's not working. I'm not sure if that is what this is using.

Change pins SSD1306Wire display(0x3c, SDA, SCL); to SSD1306Wire display(0x3c, SCL, SDA); That board have some mistakes.

For example: if You move joystick Right it will Reset. 8-)
