PS3/PC PCB for cheap dudes like me?

Haha. I have a PCB I use here and there for hacks, it’s not common GND (it’s two different potentials and it’s common VCC even!), but it’s $5 and PS3 compatible (minus a home button so usual caveats apply).

Did you have any problems with down on joystick. When I press down it cuts the pcb out for a sec or 2 . Everything else work fine. Is there something I’m doing wrong or is there something I didn’t do. Need help

Do you mean the whole pcb cuts out, or just the down direction? Your lever’s down switch may be being worn out if it’s the latter. You could jump the connection between down and ground with wire to check.

There’s the Xin-mo and Juyao encoders, some of them are 2P and some don’t have PS button but there are some that do as well.

Here’s a couple eBay links:
Juyao
Xin-mo 2P
Xin-mo 1P

You can also find them on AliExpress for around $15 or so
