[x] double-check resistors and capacitors - can I do with fewer unique values? [x] double check sd card keep-out areas with datasheet [x] swap sda/scl i2c test points [x] Do we even need any pullup/down resistors?? can't the esp32 do this internally? (update: it can) [x] i2c Pins need reassigned so they match what is on the dev boards, which use 17/18 for the OLED display. Or we somehow also squeeze an OLED into the dev boards. Or maybe replace the OLED entirely with just some LEDs to indicate sensor state?
R2: [ ] some kind of power consumption measuring chip? INA233? [ ] protection diodes on usb lines? [ ] pull-down resistor before LED strip?
