For all models of the Norbaforce (also works with the Norbauer Data Pad).
Features USB-C port, ESD protection, over voltage protection, CC1 & CC2 resistors to work with USB-C to C cables.
Finishes on Norbaforces vary greatly. They were designed for USB mini cables so it is possible a USB-C cable end may not fit depending a finish. In those cases a very light filing of the USB opening using a hobby file can enlarge the opening just enough for the cable.
(Note there is one PCB that can have a connector for Realforce 1 OR Realforce 2 models)

Note if the capacitor or resistors are out of stock they can be replaced with 0805 sized component with similar specs.
Details
Tested a sample cable using manufactured PH crimped wires in an EH cable housing end (LCSC: C161661) to make a PH to EH cable without manually crimping. Worked without issues after 350 connection cycles. Potential could use R2 daughterboard connector can be used for both R2 and R1 boards.
