− | Core EVB is a customized evaluation board for ITEAD [[Core AW204x|CORE AW204x]], which pinout 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.
| + | |
− | | + | |
− | Common A20 development boards in the market only provide Line-in/Line-out interface so that they can't drive a loudspeaker directly. However, we add power amplifier so that it can drive 4ohm or 8ohm speaker easily.
| + | |
− | | + | |
− | The dimension of Core EVB is designed according to an aluminum box, thus, this development board can be embedded into [[IBOX]].
