Product details
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.
