Question Quick tread about that XCKDIY microchip

[mastegui]

Hello everyone, I have a quick question. I’m currently designing a custom PCB for this chip and was hoping someone might have more information about it. Specifically, do all the button inputs — such as AU, AD, AR, AL, BU, BD, BR, BL, R1, R2, L1, and L2 — get connected to a button and then to VCC or GND? I want to make sure I don’t make a mistake with the PCB design.


If you have any additional information about this chip — such as preferred voltage input or how to test the signal — I’d really appreciate it. Thanks in advance!

Hello, they connect to VCC

Thanks a lot! It’s still strange that it connects to VCC — every other controller I’ve checked connects to ground. Maybe it’s just how this custom chip was programmed.

Exactly

Thanks a lot for this, it can be helpful for people that buy and use that chip. Super nice
