iomixer hats

I've published the project pages for my IOMixer HAT boards.
Project links:

• IOMixer HAT for STM32F103RCT6 Generic Board: https://oshwlab.com/devfisher/project_cojnqego
  
• IOMixer HAT for STM32F103RCT6 FK103M2 Board: https://oshwlab.com/devfisher/project_lxiegdql
  

These adapter boards let you use inexpensive STM32 development boards with the IOMixer ecosystem while remaining compatible with the IOMixer Configurator.

The goal of this project is to provide an alternative hardware platform for IOMixer using available STM32 development boards. The boards are designed for DIY assembly using commonly available through-hole components. The project pages include full details, including assembly information and design files.

I also have a small number of extra PCBs that I'd be happy to send to anyone in the USA who is interested in building one. They will be available on a first-come, first-served basis, so if you'd like one, send me a DM.

One thing to be aware of: a small hardware modification is required to support the IOMixer bootloader button. It's a simple change, and I'll explain what's required if you contact me about a board.

I'd love to hear any feedback or suggestions!

Looks good Devin. That's a lot of docs you wrote too, thanks!
The firmware for an 8MHz board is currently under the 'xperimental' folder, ie. https://iomixer.com/releases/firmware/xperimental/
Might need to organize the build targets a bit more at some point.
