The TTGO T-Beam from LilyGO is a microcontroller based on an ESP32 including a built-in SX1276 LoRa chip and a NEO-6M GPS module. The USB to serial converter makes it easy to program, even as an Arduino. The board has a micro USB connection with which it can be programmed and/or powered (the micro USB cable is not included).
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.
