From the project

1.4

History: V1.4 Add the auto reset circuit. V1.3 Improve the Mic and speaker circuit. Replace HLF-W12 to HLF-W15. Add the PWM and Power function in FPC. Fix the RJ45 LED bug. Fix some stablity issues. V1.2 First release.

Core EVB is a customized evaluation board for ITEAD Core AW204x, which pinouts the functional pins of AW204x to the corresponding physical interface such as USB ports, SD card slot Ethernet port etc. Moreover, Core EVB provides a 40 pins interface that is compatible with RPI B+, which will help developers utilize the existing Add-on more easily.
