DRV2605 (I2C) and Neopixels conflict on MDBT42Q Module

Thanks - yes, that's a good point! We could make that LRCK pin configurable - however I guess most people won't even be aware of that as a possibility so ideally we'd make it so by default it affects as few people as possible.

Are you using the bare module, or the breakout board?

On the breakout, D12/D13 aren't broken out, so if you're not using those either it'd be easy to me to tweak the firmware to use one of those? If you want to do your own build it's just a matter of changing this line: https://github.com/espruino/Espruino/blob/master/boards/MDBT42Q.py#L48

from:

     'DEFINES+=-DNEOPIXEL_SCK_PIN=23',

to

     'DEFINES += -DNEOPIXEL_SCK_PIN=23 -DNEOPIXEL_LRCK_PIN=12',

(or similar)
