This is a page to keep track of our PCB revisions, document design changes, and receive feedback.
Revision 1
PCB design decisions
- All components on top of board except clik-mate connectors and debug LEDs (also TVS diode and 3 decoupling caps)
- Board dimension target is 5 cm x 5 cm (not of vital importance)
- Mounting holes (M4) on each corner
- Mezzanine connector will be close to the center of the board
- 2-Layer PCB with 1oz copper
Revision 2
Design Changes
- Replace mezzanine connector with 0.8mm pitch equivalent to increase lifespan
- Remove extra regulator circuit
- Fix all footprints to match the Hardware Style Guide (WIP)
- Replace board info silkscreen as directed in the Hardware Style Guide (WIP) (TBD)
- Replace connectors? (TBD)
- Combine SWD and UART headers (we may be able to hack the programmers to also be UART to USB adapters) or replace them with prototyping headers
