This design uses GD32F350 as the main control. The SIM800 module uses a punctual atomic module. The ATK-SIM800C module is equipped with SIMCOM's industrial-grade quad-band GSM/GPRS module: SIM800C. The working frequency band is quad-band: 850/900/1800/1900MHz. The ATK-SIM800C module supports RS232 serial port and LVTTL serial port, and has hardware flow control. It supports an ultra-wide operating range of 5V~24V, making this module very convenient to connect to your products, thereby providing your products with voice, SMS, MMS, Bluetooth and GPRS data transmission functions. Send instructions through the remote server to control the LED of the GD32 development board to turn off and on.
The STEVAL-STMODLTE expansion board adds LTE connectivity to evaluation boards hosting the STMod+ expansion connector. It embeds an LTE cellular modem and an eSIM with a worldwide coverage.
