## DESCRIPTION
|
2018-10-10 19:00:03 +08:00
|
|
|
|
|
|
|
|
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.
