VCC=0V on DC Stepper Motor FeatherWing.2927

by ada_cw on Fri Sep 13, 2019 2:04 am

Hi,

I supplied 5V to the DC Stepper Motor FeatherWing 2927 board. However, the VCC output is 0V. The green LED on the board is on.

I looked at the schematics at https://github.com/adafruit/Adafruit-DC ... erWing-PCB. How is the input 5V converted to VCC 3.3V?

Thanks,

ada_cw

It is not. The external power input is for motors only. The 3.3v logic power comes from the Feather 3.3v pin when you stack it on your Feather.
