Small Size – the board follows the Feather Board specification from Adafruit, enabling compatibility with other boards in this standard. This also keeps the board very small (22.86 x 50.8 mm or 0.9 x 2.0 in) and low-cost.
Includes DDR3 memory – while this board is tiny, it includes 1G bit of DDR3L memory on board – very useful for a wide variety of applications.
USB interface to the FPGA – The micro usb connector is wired directly into the FPGA. Just as a microprocessor can emulate UART or SPI using standard I/O pins the FPGA can do the same for USB. A pre-loaded DFU bootloader is included – no external programming hardware is required.
