We've been busy with running the IndieGoGo campaign, but we've also been cooking up some new Open Source goodness we are announcing today!
We've created two low-cost HAT modules with small ARM MCUs on board as a great way to do smaller projects or ones integrated with a Pi.
After getting feedback from people, it looked like many folks were drawn to the larger controller system, but the other part we got a lot of interest on was the Raspberry Pi compatibility. We wanted to do a new design that hosted either an Arduino or Raspberry Pi more directly, and the opportunity to do a Pi HAT was the best option.
Originally, the idea was to create an adapter the the Pi that was compatible with our Controller modules. But after digging into the design some, the idea of creating a combined Controller Connector board made more sense. This allowed us to use a smaller and less expensive MCU, and it resulted in a design that is similar to an Arduino Uno, but with more IO, faster MCU, and plays nicely with a Pi.
You can find a full write-up on the design process at the Hackaday Project Log which documents the full process and will have a summary of what you need to do to create your own HAT. We've also made a KiCAD Template for the Raspberry Pi HAT to help start giving back into the community that created the excellent tools we use for development. The design files are already up on our github project repo. We've ordered the boards and will be testing them by next week with production happening by July or earlier.
