I approve this submission. My approved PR: 507

[cheyao]

Nice job! Just the VCC of the OLED should be connected to 5V!

#4

[Hash-AK]

so it should be connected to the same power pin than the SK6812?

[Hash-AK]

@cheyao Should be good now!

[return-misaPuding]

the 5V is connected correctly, but i´m pretty sure that this USB connector should be entirely over the board edge:


maybe adjust the edge.cuts around to make the USB part extend?

[Hash-AK]

@return-misaPuding 1) yes I corrected the 5V thing as @cheyao asked. 2) I'm not sure I understand, you mean I should reduce the size of the board so the usb float more?

[return-misaPuding]

yeah, the USB thing should stick out from the board edge, with the main "body" of the xiao flush with the board edge

[Hash-AK]

So like that @return-misaPuding ?

[return-misaPuding]

yeah, that looks like it should work correctly :>
approving with my PR #634
