    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.
