This repo collates my projects with the Alchitry AU FPGA
- Alchitry PCB Template : KiCad template for the FPGA board, provided by Alchitry
- I/O Shield with HDMI : I/O shield with a variety of peripherals including an LED matrix and HDMI. Uses original Alchitry connectors - Play Shield : Shield designed to work like a controller with two sets of directional arrow keys, 7-segment displays, LED array and HDMI.
The following is a list of boards I designed with a 1mm pitch connector instead of the original connectors that Alchitry uses: - Connector Adaptor : Adaptor board to convert the 0.5mm standard mezzanine connectors to 1mm pitch connectors -…
