I haven’t been using a Picoprobe for a while because I needed to rebuild mine and issues with the code’s dependencies and a lack of updates from the Raspberry Pi Foundation meant I haven’t been able to get it to work properly. But I did spot this doohickey: a PCB you can solder a Pico and a header. It’s a much neater way to assemble a Picoprobe than breadboard and jumper wires.
