Needs Python bindings, and also some further testing since I noticed it appeared to brown-out when I enabled the LEDs and I'm unsure if that's a wider issue or if I'm just using a flaky prototype breakout.

Seems to work with LEDs on using Pico Explorer, though even at 12.5mA they're pretty bright. Worth looking into some more.
