Alchitry Au+ FPGA Development Board (Xilinx Artix 7)

The Alchitry Au+ is the upgraded version of the Alchitry Au, featuring the more powerful Xilinx Artix 7 XC7A100T FPGA with over 100,000 logic cells — nearly 3× the capacity of the standard Au. It also includes 256MB of DDR3 RAM, a Qwiic connector for I2C integration, and all the same expandability via Element boards.

With significantly more configurable logic blocks, logic elements, and total RAM bits, the Au+ is designed for projects that outgrow typical FPGA starting points. It supports the Lucid HDL language, includes a built-in component library, and features a debugger for streamlined development.
