TTGO T-Call ESP32 SIM800L Module

 The TTGO T-Call V1.4 ESP32 SIM800L is a brand-new ESP32 development board with a SIM800L GSM/GPRS module. The new board combines an ESP32 WiFi & Bluetooth WiSoC with a SIMCom SIM800L GPRS module, and it also uses a USB-C port for power and programming rather than the more common micro-USB port on this type of hardware.

It can also function as a stand-alone board with integrated battery charging that supports up to 500mA. Apart from Wi-Fi and Bluetooth, you can communicate with this ESP32 board via SMS or phone calls, and connect it to the internet via your SIM card data plan. This is ideal for IoT projects without access to a nearby router.

 

What is the use of the TTGO T-Call ESP32 SIM800L module?

Assume you are attempting to build a remote IoT data monitoring system. The first challenge will be determining how to effectively connect your device to the internet. The internet is a constant source of frustration, whether you want to be notified when someone enters your room or water your plants from afar. In such cases, the esp32 with SIM800L GSM/GPRS Module could be quite useful. The SIM800L is a very small GSM/GPRS module that can be included in a variety of IoT projects due to its small size and adaptability.

What are a GSM and GPS module?

GSM is an abbreviation for Global System for Mobile Communication. A GSM/GPRS module is used to connect a microcontroller (or a microprocessor) to a GSM / GPRS network. GPS is an abbreviation for Global Positioning System. A GPS module receiver tracks multiple satellites and solves equations to determine the receiver's precise position and deviation from true time.
