In testing the programming jig, it turns out that the MIC2005A isn't sufficient for powering the board (I feared it might not be, but I already had one in stock and soldered onto a breakout board).
We need to find a different solution for high-side switching the 5V line (from 3V3 logic) to replace it.

Have wired the new power switch up, and it seems to work okay. However, once I'd programmed the board it dropped into a crash/reset loop rather than coming up cleanly. Powering it up outside the jig it seemed fine.
Wonder if there's maybe not enough power from the power supply. It'd be good to try with a beefier PSU, or trying a cap on the 5V line nearer to the board
