LilyGO TTGO T-Beam - LoRa 433MHz - NEO-M8N GPS - ESP32

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

In addition, the T-Beam can also be used 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.
