The Spartan Edge Accelerator Board (SEA Board in short) is a lightweight FPGA development board, it is based on the Xilinx Spartan-7 chip and follows the Arduino shield form factor. Hence, you can use it as an Arduino shield to driver an LCD and a camera or as a stand-alone FPGA development board. Besides, with the help of on-board ESP32 chip, the SEA board also enables your Arduino with WiFi and Bluetooth function.

Spartan-7 is the newest and most cost-effective FPGA chip among Xilinx’s FPGA family, offers the best in class performance per watt. On top of that, we provide the full FPGA APIs for Arduino, which means Arduino users are able to use the FPGA function without knowing anything about FPGA. This board will broaden Arduino’s capability in many ways like simple image processing and computer vision application, signal encryption and decryption, and signal sampling and processing.

FPGA Specifications

Attention

The SEA shield's IO voltage is 5V, and the FPGA's IO voltage is 3.3V, so we made a voltage divider to make the IOs voltage compatible. The 3.3V IO voltage of the SAM D21 series will be less than 3.3V after voltage division, which is not enough to drive the FPGA's IO. Therefore, at present, the SEA development board only supports the 5V IO Arduino board, such as Arduino UNO and Seeeduino V4.2.
