shares diagram on trying to 3wb bootloading, using Teensy and level shifter breadboard
@David Burnett asks for code that will exercise the GPIOs
@Kristofer PISTER what test code has @Tengfei Chang built?
@Austin Patel shares his test code: https://github.com/austinapatel/scum-test-code/blob/austin/scm_v3c/AllGPIOToggle.bin (include all-GPIO toggle, 2mA current)
@Alex Moreno suggests monitoring current draw of the board
@Alex Moreno indicates need to leave
VDDD connected during optical calibration
@Fil Maksimovic indicates we don’t have a 3wb calibration, asked Mark whether could work on that using nRF.
