1. SIM900L Description
1.1 Summarize
Designed for global market, SIM900L is a quad-band GSM/GPRS module that works on frequencies GSM
850MHz, EGSM 900MHz, DCS 1800MHz and PCS 1900MHz. SIM900L features GPRS multi-slot class 10/
class 8 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.
With a tiny configuration of 24*24*3mm, SIM900L can meet almost all the space requirements in user
applications, such as M2M, smart phone, PDA and other mobile devices.
SIM900L has 68 SMT pads, and provides all hardware interfaces between the module and customers’ boards.
z Serial port and debug port can help user easily develop user’s applications.
z Audio channel which includes a microphone input and a receiver output.
z Programmable general purpose input and output.
z The keypad and SPI display interfaces will give users the flexibility to develop customized applications.
SIM900L is designed with power saving technique so that the current consumption is as low as 1.0mA in sleep
mode.
SIM900L integrates TCP/IP protocol and extended TCP/IP AT commands which are very useful for data transfer
applications.
