LilyGO TTGO T-Beam - LoRa 868MHz - NEO-M8N GPS - ESP32

The TTGO T-Beam from LilyGO is a microcontroller based on an ESP32 including a built-in SX1276 LoRa chip and a NEO-M8N GPS module. The CP2104 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) .

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.

Note: It may be that a shorter version of the LoRa antenna is included. This will have little or no effect on the range of the module.
