Quad-band GPRS/GSM Shield for Arduino UNO (SM5100B-D Module)

Quad-band GPRS/GSM Shield for Arduino UNO (SM5100B-D Module)



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

Two jumpers can be used to select if the SM5100 module is talking to soft serial port, serial port of arduino, or USB.

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.
Connect RX to MRX, and remove atmega328, so USB port of arduino can be used to directly to talk to SM5100B.

Connect RX to MTX,  and keep atmega328, so SM5100B can talk to the MCU.
