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.
There’s limited information about the board, and basically, all we got is this Github repo with a link to an Arduino sample, a library to control Seeduino GPRS, as well as datasheets and AT commands set for SIM800. Checking out Seeeduino GPRS Wiki may help getting started with the TTGO T-Call board.
- The wireless module is integrated with ESPRESSIF-ESP32 240MHz Xtensa dual-core 32-bit LX6 microprocessor.
- It needs a power supply of 5V/1A and has a Type C port.
- It features 802.11 b/g/n wifi protocol and Bluetooth v4.2BR/EDR and BLE standard protocol.
- The wireless communication module supports cloud server development and SDK for user firmware development.
