2.54, 2.8 and 3.0 :-(

I really hate the hole in the side of the puck for the usb connector. And it’s time for a new layout Puck 2.0 so how to charge and program the boards. (yes after the first time programming is OTA). Pogo pins on the top seems the answer. Behold (chorus of angels) 4 pin magnetic pogo pin connectors !!! yes ! The nice usb cable on (yes not high speed usb c, but it will work) has a pin pitch of 2.45mm (that’s tenth of an inch 0.1”), AliExpress has ones with a 2.8mm pitch and no cable, and Digikey has those and 3.0mm. pitch. Time for more coffee, sigh.
