I added a trackpoint to a corne-cherry (crkbd) keyboard for ergonomic pointing bliss!

Super nice!

How much did you pay for the trackpoint and shipping? It's great to hear that you can just email Sprintek!

Nice that the RP2040 doesn't require a reset circuit! I just finished a handwired with a ATMega32U4 ProMicro where I needed to remove a resistor to clear the D5 pin for USART. That was quite a painful process overall. This seems significantly easier!

    Thanks! I paid $28.55 per SK8707 module + shipping (around $22 to Norway).

    Ok, I gæs it'd be about the same shipping to Denmark. Compared to sourcing from ThinkPad keyboards, I find it very appealing to not have to risk popping the pin pads of the pcb when desoldering the keyboard ribbon cable. I've caused a few casualties.

    Edit: Ah, I see you had to undsolder a ribbon cable from the controller board, too.

    You don't have to desolder the ribbon cable. You could use some sort of ribbon cable connector, if you have one available. But I found it more practical to only have the wires I needed. And desoldering the ribbon cable was fairly straightforward.
