Since there where rumors that we might get a MicroMod compatible T4 I read a bit into this platform and like it very much since it would make integrating Teensies in custom boards much nicer.
So, I spent the rainy weekend designing a quick and hacky board (hopefully) compatible to the Teensy 3.2. https://github.com/luni64/MicroMod_3.2
After decades of using EAGLE this is my first real KiCad board. So, forgive me if the data in the repo are not as they should be. Still don't fully understand how the library system is supposed to work.
I was able to do the layout on a 2 layer board. However, I wasn't able to do it with the usual 6/6mil rules but needed go down to 5/5mil which, unfortunately is a bit more expensive.
Schematic: View attachment schematic.zip
Features:
The connector would allow for much more signals but since this is just a quick experiment I did't spend additional hours in routing those.
Here a few links to general micromod info

Features:
- 8bit bus: PTD0 - PTD7 (D2, D14, D7, D8, D6, D20, D21, D5)
- Differential AD (A10, A11 / A12, A3) (however, only very primitive reference voltage generation)
- Serial1, Serial2 (D0, D1, / D9/D10)
- CAN (D3, D4)
- SPI (D11, D12, D13, D15)
- LED on D16
- SWD_DIO, SWD_CK (JTAG) (bootloader chip can be disabled by a solder bridge)
