Alchitry Au FPGA Development Board (Xilinx Artix 7)

The Alchitry Au is a powerful FPGA development board featuring the Xilinx Artix 7 XC7A35T-1C with over 33,000 logic cells and 256MB of DDR3 RAM. This SparkFun version adds a Qwiic connector for easy I2C sensor and actuator integration alongside the full FPGA capability.

The board provides 102 I/O pins at 3.3V logic (20 switchable to 1.8V), nine differential analog inputs, and a 100MHz on-board clock that can be manipulated internally by the FPGA. A USB-C connector handles both configuration and power, with a USB-to-serial interface for data transfer. All Alchitry boards support the Lucid HDL language, include a built-in component library, and feature a debugger.
