On off shim pins

Does the On/Off Shim actually use all 12 pins that it gets soldered to?

In other words, if I were to not attach it directly to the Pi, and not use headers (so I’m soldering individual wires between the shim and the Pi), do I need to do all 12 wires?


The pinout is here https://pinout.xyz/pinout/onoff_shim# Looks like it only uses 4 pins.
A link to the pinout is usually on the product page. Looks like they forgot it this time though, https://shop.pimoroni.com/products/onoff-shim I don’t see it.

Thanks, I saw this page and this is actually what caused my confusion. Maybe I’m reading it wrong, but it looks like it’s using 6 of the 12 pins to me… 3v3, 5v, two ground pins, and two GPIO pins… is that right?


Correction, 5 pins (I think). BCM 17 isn’t covered by the 12 pins on the PCB

Yes 6 pins, I missed the two grounds when I first took a quick look at it.
BCM 17 would be covered if you install it correctly

Oh duh, that’s right. I forgot how to count yesterday I guess. Ok thanks, gonna try running just the 6.
