## PSU Baseboard / Bus Head
This is a circuit & mount for a small desktop DC PSU and embedded system bus-head. Documentation is sparse.
This is a circuit & mount for a small power supply and embedded system bus-head for the [uart-clocked bus](https://gitlab.cba.mit.edu/jakeread/ucbus-notes).

![schem](log/2020-08-03_schematic.png)
## TODO
- add CAD for PSU mount here,
- add image
- revision circuit for:
- solder jumpers default shut for 5v usb-to-bus
- clear LED indication of 24v presence, 5v presence on bus

I use this board mostly as the 'coordinator' for modular motion systems, firmware is [here](firmware) and uses platform.io to run, see [this guide](https://mtm.cba.mit.edu/2021/2021-10_microcontroller-primer/fab-platformio/) to build and load code.
