I’m handwiring a left side 3x5 Corne using the Helios RP2040 to be used for gaming. Can the 5 row wires can be wired anywhere, I want to go #20, 22, 26, 27, & 28? That then gets defined in the firmware. Which also needs to be in a “uf2” format? What’s the easiest way to get started with the firmware for this MCU?

    Since it’s for an existing keyboard, ie the corne, it’s very likely that QMK (the most common firmware) already have the columns and rows defined. Look at the firmware for the Corne and follow how it’s set up and solder to those pins in that order. That’s a lot easier than the opposite.
