To be brief I am in the process of modding my Vita to add a USB Type-C port instead of the microUSB mods that I have seen. Technically speaking on paper there should be no problem with this as Type-C is backwards compatible. You simply just need to wire only VBUS, D+, D-, and GND and you wouldn't use CC1/CC2. However, I've hit a snag in my process, it may be possible that I've damaged a fuse on the board?. I'll try and break all my problems down into key points:
- What gauge wire is used for this and what is a good supplier that ships/sells it to the US? I only have 30 AWG on hand (one is a solid wire, other is threaded) neither of mine seem to be thin enough to get a proper solder. I managed to read somewhere that 36 AWG is used, but Amazon only goes up to 36 AWG and I can't find and 36AWG that is is both solid wire and coated.
- Do I really need pull-up/pull-down resistors on CC1/CC2 pins of my Type-C connectors? I have two Type-C breakout boards. One features the 5.1K ohms resistors already in place. It also has a nice pinout already in line for easier/quicker solderin. The other breakout board has none and is significantly thinner/easier to place. So far I have only used the one with resistors for safe testing.
- Is it possible to have stripped the pads on the microchip/alternate solder points used for D+/D- on the Vita motherboard? I could not get anything to stick while soldering and recently ordered a smaller microscope that will be here in a day or two in order to verify. I eventually opted to solder directly to the multi-use/charging port pins and it was much easier. On that note...
- My Vita no longer charges even using the normal port after soldering. It still turns on and everything else appears to work, but I'll have to go back with my microscope to check for possible bridging as I think that may be the issue? I am also concerned that it is a possibility the fuse labeled "SB" was damaged where you connect V+/VBus to. If so what is the actual module name so I can desolder and replace it?
I know this is a lot of questions to process, but please help where possible, any help is appreciated.
The USB-C breakout boards being used:
- No pull-down resistors
- With pull-down/up resistors
