HP Prime to usb-c mod help - OnyxVortex - 09-30-2023 03:05 AM
Hello, I have been using the prime for a while but have wanted to change the port to type c. I tried to find general information about micro b to usb c mods that preserve data but I couldn't figure it out. Would anyone here know of any such mod. Also, is there any way to send data to the calculator without usb, if I go the charging only route? Thanks.

You could get similar benefits using a magnetic USB Micro-B data cable and leaving the business end plugged into the calculator.

It's not a trivial task and you'll need to know how to solder. The easiest solution might be to leave the micro b port for data transfer then make a cutout for a USB c port somewhere else and just use it for charging.

I’ve found that many aren’t familiar with these things, so I’ll attach some photos I took of one --- in case that might help comprehension for some following this thread.

Note that the HP Prime's port is recessed, so you'd want to keep that in mind when shopping for such a cable / insert combo. (At least that was a concern of mine.)
Another atypical micro-usb cable I purchased around the same time was one with a symmetrical plug (180° rotational symmetry at the plug end).

Also part of the reason I am interested in usb c is interoperability, which such a system would not give without purchase of many cables and adapters.(09-30-2023 09:56 PM)ijabbott Wrote: … a magnetic USB Micro-B data cable and leaving the business end plugged into the calculator.
