Here is a third ESP32 packaged board so as to enable easy presence detection and retrieve Xiaomi sensors data.
Added to that you get a small IR emitter, a buzzer, an integrated battery and several buttons:
- 5V DC power supply
- USB Type-C
- 4 MByte Flash + 520K RAM
- 9-Axis IMU MPU9250(only gray type)
- Red LED
- IR transmitter
- 1 Buttons, OLED(1.3 inch), 1 Reset
- 2.4G Antenna: Proant 440
- 80 mAh Lipo Battery
- Extendable Socket
- Grove Port
- Wearable & Wall mounted
The board is available on platformio.ini file with BLE & IR gateway and Button reading.
Currently the buzzer and the OLED are not used in this implementation, if someone wants to play with that and submit a Pull Request, I think there is some fun to have with this new board!
