Overview
Core EVB is the evaluation board customized for ITEAD CORE AW204x. It leads the functional pins of core A20 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 resources to make a better project. The common development boards in the market only provide Line-in/Line-out interface so that they can’t drive loudspeaker directly. However, we add level 1 power amplifier circuit on the board’s back, which drives 4ohm and 8ohm headset with ease.
The dimension of Core EVB is designed according to the aluminum box size of IBOX, thus, this development board can be embedded into IBOX aluminum box.
