Product Overview

This is an Arduino Shield for SM5100 quad-band GSM/GPRS module. The module is included.

Due to the large current of the GPRS module, a wall adaptor is recommended: http://store.linksprite.com/wall-adapter-power-supply-12vdc-1a/

USA providers are all on 850/1900Mhz and pratically all the rest of the world uses 900/1800Mhz.


The shield must be powered by a wall adapter with 12V, 1A.

Hardware Jumpers Explain:

  • J1 and J2 are used to choose how RX/TX of SM5100B is going to connected to Arduino.
  • RX/TX is the RX/TX of SM5100B module.
  • MTX/MRX is the TX/RX of Atmega328.
  • D3 and D2 are the I/O of Atmega328 if soft serial is used.
