design more robust debug probe

Open Sheepy3 opened this issue 11 months ago • 3 comments

@V205Arduino designed a debug shim for the sprig, which works excellently to breakout the UART for connecting an official pi pico debug probe. https://www.raspberrypi.com/products/debug-probe/

as its schematic is open source, it should be possible to recreate the debug probe directly on the shim. Instead of exposing the UART port through a connector, it can be directly wired to the UART pins exposed on the original shim. the schematic can be found here: https://datasheets.raspberrypi.com/debug/raspberry-pi-debug-probe-schematics.pdf?_gl=1zdfq3y_gaMTk5NTE0NjkxOS4xNzA5OTI1MjU0_ga_22FD70LWDS*MTcxMTExNzQ3OS43LjEuMTcxMTExNzUyNy4wLjAuMA..

Another improvement to be made is the reset button on the shim. it would be ideal to find a bigger button, as the original is a little too small.

Another requirement is that the project, whatever software its designed in, be setup to export pick and place and BOM files, to make pre-assembled ordering possible.

I'll try to do this later, will probably be done in a few weeks I think

Sorry, no progress, I could either attempt to start working again on this in two months(I won’t have access to a laptop/desktop until then), or close this issue as stale.
