Core EVB is the evaluation board customized for ITEAD [[Core AW204x|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.'''
