(1/1)

Hi! I want to share with you my last design. It's a breakout board for the SIM900 GSM module. Fits in a 50x50 mm board, and has an IO connector with many of the signals you need to control it. Also, as the board is designed to work with a battery, it also includes all the necessary components to charge and manage it. The internal power supply is 3.0V, so external controller must be work at this voltage. Here's the complete board info: http://www.jechavarria.com/2013/09/30/sim900-breakout-board/
