This part should do what you want with a few problesm. Pcb view has been suppressed as not useful (the cpu board pcb will appear in pcb.) You can drag the appropriate CPU board in to breadboard and it will mostly connect like this:

Here the CPU board is a pin off from the female connectors, move the cpu board one pin left and it will connect

like this (note all the connections go green indicating a connection.)

In schematic if you move the cpu board schematic correctly it will mostly connect (it will be at a random position to start and needs to be moved!)

It mostly connects, except for a few of the grounds (as only one connection to a net is allowed to a bussed net in schematic) which leaves no connection on AGND and several nets not routed in the status bar, but this is as good as it gets AFAIK.

Thank you very much for your help!
Do you have an idea how to connect a capacitor in parallel to the battery contacts?
on the board, the battery clamp solder bumps are in the middle of the upper and lower end of the board on the side, where th pi pico is placed in.
Best, Kai

In a word no :slight_smile: , also no idea why you would want to place a capacitor across the battery. The battery is essentially a capacitor, there doesn’t appear to be a reason to put a capacitor across it. A capacitor may affect how the charging circuit works and therefore be dangerous as well. LIPO batteries are dangerous devices and best left alone by and large.
