Description:
SIM800L module can support 4-band GSM/GPRS, and the working frequency bands are GSM850, EGSM900, DCS1800 and PCS1900MHz.
The size of the module is only 17.815.82.4 mm, which can almost meet the requirements of space size in all user applications.
The physical interface between the module and the user is 88Pin LGA pad, which provides all the hardware interfaces of the module.
Up to 50 keys can be supported. All the way full function serial port.
One USB interface can simulate one serial port, which is convenient for users to debug and download software
Two audio interfaces, including microphone input and receiver output.
Programmable general purpose input/output interface (GPIO).
All-way SIM card interface
Support FM function
Pwm function pin
