@yezzer Right, so the lipo shim sits over the Pico (on the specific pins) but the GPIO pins are just through - and not connected to any lines on the lipo, so you're good to use them sandwiched together.
It's the LED ring that you'll need to solder with wires (it maps to a Pi but not a Pico, so you'll need to find these manually - INT goes to, in this case, GPIO4 on the Pico - but guessing you might be able to change in software).
