content: Hello everyone, new arrival here.I have a pair of walkie-talkies Motorolla T82 Extreme which I like, but they use MicroUSB port for charging. I want to make those Type C chargeable (just to have less variety of cables at the charging station).When I disassembled one of them, it apper there might be enough space for the new PCB with the Type C connector and the schematic might be rather simple (USB C connector, a pair of resistor for data lines, a few capacitors before and after power filter, plus a few extra 5K1 resistors for CC pins):However, at the stage of recreating dimentions, I encountered the other issue. The regular Type C connector has a mounting holes that overlaps with the mositioning holes of the PCB in a casing:Particularly, the round one to the bottom-right corner of USB coneector is M2 screw with a rather large head. Than I recalled the Adafruit compact USB C Socket Breakout board (Adafruit 5180, a.k.a. JRC-B008) or a simmilar JRC-223, but I can't identify the partnumber of the used USB connector so I could find the dimentional drawing and make a KiCAD footprint for that.Could someone either:- help to identify the part-number and help to get the dimentional/mechanical drawings of such USB type C connector?- suggest the part-number of similar connector that is sourseable (by the hobbyist, not a company) from the suplier/retailer and the mechanical drawing can be found for it?Perhaps, some water-proof USB Type C edge connector?Thanks!

content: The water and dust protection is ensured by a separate cap for the chaging port (to be more precise, the sealing plug in the casing). There is no sealing ring on the microUSB itself, and there are some gaps around it too.Perhaps, the water-proof edge Type C connectors are also existing.

That EB-500-5005 is indeed looking like a connector on a different breakout board:I also found something simmilar, but with 16 pin (might be a bit easier to solder) on aliexpress:Hoewever, no dimentinal drawing are attached. Do you know any part-number like that?

content: Fair point. Just wanted to make like easier later at point of manual soldering.P.S. On a second thought, it looks like they are using some sort of vertical connector instead of edge one.P.P.S. So far I found these options that might work.

content: Good Morning Araneus0390, have you given any thought to 'Micro to type C' adapter, like these?https://www.amazon.com/Adapter-3-Pack-Converter-Compatible-Samsung/dp/B0997PQ2QB/ref=asc_df_B0997PQ2QB?tag=bngsmtphsnus-20&linkCode=df0&hvadid=80608063550952&hvnetw=s&hvqmt=e&hvbmt=be&hvdev=c&hvlocint=&hvlocphy=104684&hvtargid=pla-4584207592011756&th=1
