Description

TTGO T-call is a modified ESP32 (ESP-WROVER-B 8MB PSRAM) development board with an integrated SIM800L 2G/GPRS module. The USB Type C pluggable board includes an integrated LiPo Battery Charging Circuit & Connector and is an excellent solution for developing IoT applications. Aside from Wi-Fi and Bluetooth, you may use GSM/GPRS technology to communicate with this development board, and you can connect it to the internet using your SIM card data plan. This is ideal for IoT applications without access to a local router. The TTGO T-call kit comprises header pins, a battery connector, and an external PCB antenna that may be connected to your board.
