I am actively working on this project. I have completed the hardware designs for the first prototype, including 3D models, schematics, and PCB design. These will all be listed below. My next step is to manufacture the PCB at home using a photoresist film. I will etch the copper board using a HCL and Peroxide solution.
Here is my schematic drawn using circuit-diagram.org.
The ESP32-S3 only has four RMT TX ports, so I cannot output data to each of the six addressable LED panels simultaneously, I have chosen to connect three contiguous displays each to their own port, so these three displays will be the most responsive, and will be used for anything where low latency is critical. The other 3 displays will be daisy chained to the remaining port.
I needed to redraw the circuit in Autodesk Fusion to create my PCB, and I reduced the number of total buttons, along with making them all individually readable.
Here is a PCB preview of my design from fusion’s CAM preview.
