You are looking at an unsoldered TTGO T-Call ESP32 SIM800L module with SIM antenna and SIM card support. This module serves as a wireless communication module, allowing any microcontroller to connect to your WiFi network using the ESP V1.4 ESP32 Serial WIFI Wireless Transceiver Module. The ESP32 module is a self-contained SOC with an integrated TCP/IP protocol stack.
With its GPIOs, this module can easily be paired with sensors and other application-specific devices, requiring minimal development and runtime loading thanks to its powerful onboard processing and storage capabilities.
The TTGO T-Call combines an ESP32 development board with a SIM800L GSM/GPRS module. This combination enables wireless connectivity using the ESP32's WiFi and Bluetooth capabilities, alongside the SIMCom SIM800L GPRS module. Notably, the board features a USB-C port instead of the more common micro USB port for power and programming.
Let's consider a scenario where you aim to build a remote IoT data monitoring system. One of the initial challenges is establishing a reliable internet connection for your device. Whether you need to receive alerts when someone enters your room or remotely water your plants, the ESP32 with SIM800L GSM/GPRS Module can prove highly valuable. Its compact size and versatility make the SIM800L an ideal choice for various IoT projects.
The ESP32-based wireless communication module is best for IoT applications because it consists of a USB Type C pluggable board that has an onboard LiPo Battery Charging Circuit & Connector.
