For anyone finding this looking for info, here is some stuff I could figure out:
- That's a knockoff RCMx86 sold by Aliexpress and the like. It has a different pinout.
- It most likely does not support UF2 mode, at least I couldn't get mine into it. The reset pin seems non-functional.
- Based on the diagrams given by the Chinese manufacturer, I don't think it has a USB strap option.

Here is a pinout I found online, supposedly from the manufacturers of this knockoff:

Based on that, it looks like pad A is supposed to be the Joy-Con, and pad B is for Vol +. However, they seem interchangeable based on my experience and various install pics I've seen.

EDIT:
I just realized mine is an EVEN WORSE KNOCKOFF than yours! It doesn't even use a SAMD21 chip! So maybe yours does have UF2 mode. Here is the chip I have in mine that I thought was the same as yours:

I have the same board and the same chip.
I can work out the D+ and D-
But A, B and the 2 points between 3.3v and gnd I can't work out.

Did you work it out in the end?

This is just a replacement for a payload injector like the RCM Loader.
It can only be used for unpatched Switches.
It connects to the USB port and it needs not wires for power.
It is not a mod chip for patched Switches like the OLED or the Lite.

This is a good installation video :

So I have the same chip as well. It seems to work with both A and B for Dat0. But my problem is when I connect that my right joy con doesn't recognize when I slide it on the rail. If I disconnect the wire the right joy con works fine again. Otherwise it all works. Any one else have this problem or anyway to fix it?

Hi, Did you ever solve this issue as I am facing exactly the same thing? Cheers
