SIM800L Overview
SIM800L is a quad-band GSM/GPRS module, that works on frequencies GSM850MHz, EGSM900MHz,
DCS1800MHz and PCS1900MHz. SIM800L features GPRS multi-slot class 12/ class 10 (optional) and supports
the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.
With a tiny configuration of 17.8*15.8*2.4mm, SIM800L can meet almost all the space requirements in
customer applications, such as smart phone, PDA and other mobile devices.
SIM800L is a LGA package with 88 pads, and provides all hardware interfaces between the module and
customer’s boards.
Support 5*5*2 keypads
One full modem serial port, customer can configure two serial ports
One USB, the USB interfaces can debug, download software
