Finishes on Norbaforces vary. They were designed for USB mini cables so it is possible a USB-C cable end may not fit depending a finish (I want to say this happened in 2 out of 8 cases). For those cases a very light filing of the USB opening using a hobby file can enlarge the opening just enough for the cable. To get an idea of how compatible a case is take the existing daughterboard out and see if a USB-C cable end will fit in. (It will be tight but if it fits and there is a little wiggle room your should be all set)
Thanks to @insolentpotato for driving this project which took a few different variations to get it just right. @techbeezin for testing and @Cipulot for advice and listening to a lot of back and forth.
QMK firmware is recommended - Enter DFU mode without having access to the physical rest switch with command keycode enable. (Although, there is a known issue of this port regarding not registering the board after computer reboot.)
Not sure if anyone is working on that port/registration issue, however would be happy to see something like that if someone else takes up the reins. For now +1 to the Cipulot R1 pcb for onboard programmability.
