GPIOx10 MIC (ME-00044-1A)

ABOUT
The Magzor GPIO MIC provides you with 10 mixed signal inputs/outputs (analog and digital) for communication with all devices in your project. The board has 10 3-pin stacks that can be used for digital input and output, of which 6 can also be used for analog input and 5 can be used for analog output. Connecting devices is easy using the GPIO MIC's right angle 0.1 inch-pitch headers.

Power
The board accepts 3.3 V input and source power at 3.3 V to any the attached devices. The GPIO MIC pairs very nicely with the Power Shield MIC for power supply and I2C communication.

Connectors
The board has 10 3-pin right angle headers for connecting devices and two standard MIC stacking headers for power and I2C communication as well as a 3-pin right angle header for programming the microcontroller.
