This is a TTGO TCall & SIM800C-DS V02 ESP32 WIFI Bluetooth Nano Card Slot SIM800C Development Board. The Module is a custom ESP32 based development board with an onboard 2G/GPRS Module SIM800C. The new board combines ESP32 WiFi & Bluetooth WiSoC with SIMCom SIM800C GPRS module, and also happens to rely on a USB-C port for power and programming instead of the more common micro USB port on this type of hardware.
