• WOHO!

    It's running Espruino and flashing some LEDs :D

    Summary of mistakes:

    1. Forgot to route NRST....
    2. Made a silly mistake with one of the decoupling caps (such that I had VDD and GND shorted...
    3. Missed fine print in USB datasheet about the footprint being from bottom not top so it is mirrored. I fixed it by soldering the connector on vertically (which effectively mirrors the pinout)

    New revision will be ordered before the end of the week, correcting all this.
    I've learned a lot so far! Debugging, fine pitch soldering, and SMD reflow and rework. Phew
