For more information and to get started with the board, see the following page: TTGO T- Beam.

The T-Beam can also be use with the SoftRF software: SoftRF ESP32

To program the board with the Arduino IDE select the 'ESP32 Dev Module' in the board manager.

*Note : The pins on the board are directly connected to the ESP32 chip and are therefore only suitable for 3.3V signals.
