LilyGO TTGO T-Call ESP32 - with SIM800C
The TTGO T-Call from LilyGO is a microcontroller based on an ESP32 in combination with an SIM800C GSM GPRS module. The USB to serial converter makes it easy to program, even as an Arduino. The board has a USB-C connection with which it can be programmed and/or powered (the USB-C cable is not included).
See the following page to get started with the board: TTGO-T-Call-ESP32
To program the board with the Arduino IDE select the 'ESP32 Wrover 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.
