The T-Beam from LilyGO is a microcontroller based on an ESP32 including a built-in LoRa chip and a GNSS 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 (micro USB cable not included).
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.
