Same reason i went with rp2040 this time instead of Arduino pro micros, the rp2040 zero costs less than £1.80 where Arduino costs £7 now.
I got the connector from AliExpress a box of them was around £1.70 so dirt cheapo, free delivery too if you spend more than £8 from the choice select stores, easy to do when buying the rp2040 zeros too.
Case i made myself on tinkercad, 11th revision works for me although i can see areas where it could be improved but does the job fine. I will put case up on thingyverse so others can benefit from it or even make it better.
My old cab uses 2 arduio pro micros with daemonbite firmware.
Rp2040 is much more cheaper alternative and more customisable.
