U3 IO Shield for ODROID-U3 (Hardkernel)

U3 IO Shield is the board that can be plugged on the neat of ODROID-U3 via tiny 8 pin IO connector. You can have 36 IO ports of GPIO/PWM/ADC.
The shape and dimension are exactly same as ODROID-U3. It comes with 12pcs of PCB spacers for easier and solid stacking assembly.

The IO Shield board is designed as versatile, general-purpose data acquisition and control module and provides a direct connection to ODROID-U3 IO connector. We added lots of basic but essential goodies. First up, there is a big prototyping area, so you can wire up DIP chips, sensors, and the like. Along the edges of the proto area, all the GPIO/ADC/PWM and power pins are broken out to 0.1" stips so you can easily connect to them. There are also two 3-pin headers for small servo motors connection. 

If your ODROID-U3 PCB is rev 0.5, you can access the HW SPI of Exynos-4412 CPU.
We added a SPI Flash memory SST25WF020A on the new U3 IO Shield Rev 0.3.

Finally, we added a 10-pin connector of I2C/GPIO for further expansion.
