@User: Not yet. It's not particularly urgent; just needs to be done in the next month or so. If you have a wish list for the PCB, let @User know.

Maybe we can use this thread to build a wish list

Yes, the design will be done in KiCad and put in the caravel github repository.

I'd like to be able to measure the power draw for each rail if possible

I have a design-idea for the measurement of the power-draw of each rail: You put male headers and jumpers on the board next to the connector where that rail is used. Normally the jumper is on and just lets you use the rail normally. When you want to measure the power-draw of a rail, you take the jumper off and connect an ampere-meter to the header instead of the jumper. That way you can also easily add probes for oscilloscopes, or use the whole board as a breakout board for the connector when needed, or insert a relais so that power supply for a device could be automated. Might not be applicable for high-speed signals or for very dense boards.

This is the one I was thinking of before https://github.com/samlittlewood/caravel_carrier

I'm all for breakouts and flexibility, but I would also prefer being able to measure the current using automated methods accessible via a SPI bus that could be accessed via the pico32 or an external controller
