Description
Powering module for c-uGSMandd-u3G systems which also provides conversion of logical signals. On the board is a place for soldering the DC connector (sold seperately). The system accepts the supply voltage from5 V to 16 V. The output voltage is 4 V with the voltage of 600 mA(temporary up to 2 A). Board sizes are35 x 21 mm.
Pins
The pins were divided to a part connected to the main microcontroller and to the part connected to the GSM module.
