Hi, I'm fairly certain this is not an issue with this board, but I'm having an issue with some boards I ordered. I'm using a wemos esp32 mini like you are.. confirmed pinouts are the same. I'm having the same issue with everything wired to your board as I was when I was just hooking things up with dupont cables.... which is that everything is red! I can only get VERY faint green and if there's any blue at all it is almost invisible. If I print something in white it basically just displays in red since it's really showing blue or green colors.

At the moment I only have the esp32 and female connector on the bottom attached to the board. it looks like you have other things hooked up.. but I'm not an engineer and don't understand the schematic. I was curious if you'd recommend hooking anything else up for troubleshooting. perhaps c1 c2? or something along those lines?
