The MUB - An ultra-compact, modular processing unit
What is it?
A tiny, modular, all-in-one processing board. On it's own, it can't do much. But this board can be integrated into just about any other board. All of the mcu pins and power lines are accessible through the low-profile connectors, providing the maximum mcu potential for any project.
So what makes this better than an Arduino/Blue Pill/Feather?
Well, a few reasons...
- Super compact 32mm x 23mm size
- Powerful Cortex M4 120MHz mcu
- Access to EVERY SINGLE PIN (41 total GPIO)
- Super tiny and low profile board-board connectors
- Onboard 5v and 3v3 regulators (Supports up to 32V input)
- $10 BOM cost at qty 1, $7 at qty 10
- Broken out programming header for easy access
Cool, I want one!
Great! Then build it yourself :) I hope to sell these boards once the global chip shortage resolves itself, but for now you are on your own!
The gerber files to order the board are found in this repo. Order at your own risk.
A probably up-to-date BOM can be found here
A custom package for kicad exists in the libraries folder, so you can easily integrate the mounting footprint into your own board and simply connect a MUB in the slot.
Godspeed.

Questions
How big is the KiCad Schematic PCB?
It measures 32 × 23 mm and has 4 copper layers, 1.6 mm thick.
What parts does the KiCad Schematic use?
43 parts, built around the ATSAMD51J19A-MU, AP2112K-3.3, 10118194-0001LF and CGRTS4004-HF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the KiCad Schematic KiCad files?
From the DDeGonge/MultiUseBoard repository on GitHub, at the commit this page was made from: the board is MUB_pcb/KiCad Schematic.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the KiCad Schematic design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
