DE0-Nano Development and Education Board • FPGA-017

The DE0-Nano board introduces a compact-sized FPGA development platform suited for prototyping circuit designs such as robots and “portable” projects. The board is designed to be used in the simplest possible implementation targeting the Cyclone IV device up to 22,320 LEs.

The DE0-Nano has a collection of interfaces including two external GPIO headers to extend designs beyond the DE0-Nano board, on-board memory devices including SDRAM and EEPROM for larger data storage and frame buffering, as well as general user peripheral with LEDs and push-buttons.

The advantages of the DE0-Nano board include its size and weight, as well as its ability to be reconfigured without carrying superfluous hardware, setting itself apart from other general purpose development boards. In addition, for mobile designs where portable power is crucial, the DE0-Nano provides designers with three power scheme options including a USB mini-AB port, 2-pin external power header and two DC 5V pins.
