RPi Zero W i2C pinout for featherwing 4 digit 7 segment disp

Post by casspencer »

I reviewed the tutorials posted on adafruit, but was not able to figure out the pinout on the featherwing (which pins on pi zero connect to which pins on the featherwing). For reference, I have the following featherwing backpack connected to the accompanying 4 digit 7-segment LED, here: https://learn.adafruit.com/adafruit-7-s ... gs/pinouts. It is unclear from the picture which port on the featherwing is ground, 3v, sda, and scl.
i2c is enabled and installed on the RPi zero w as well as all associated packages required per the instructions.
output:

sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

Any help/recommendations appreciated.

The FeatherWing's pinout is the same as the Feather it would plug into.

The I2C pins are on the side with 12 pins, at the end farthest from a Feather's USB jack. The 3v and GND pins are on the side with 16 pins, and the end closest to the USB jack.
