M5Stack SIM800L Module
DESCRIPTION
The M5Stack SIM800L Module is a module with small SIM800L GSM/GPRS module. You can program it after connected to any series of M5Stack Core through Blockly, Arduino or MicroPython.
SIM800L is a complete Quad-band GSM/GPRS solution. SIM800L moudle could be connected with M5Stack Core via a serial port named USART2. Absolutely, you also can change the serial port number with jumper by your own.
