guhh i would really have liked if this grove connector wasn't on this side of the board, probably going to remove it and solder straight to pads
the height (and the added width if i was using a grove cable) would make designing a case around it awkward
jeez! i thought i'd received a dead pico2w (didn't test it before installing the shim, mea culpa) but no! you need to press the power button on the shim even without a battery and plugged into usb, then the pico works as intended!
