Why is it missing one of the 2 PSUs? I have a tradition in my work. Every time I issue a first revision of the board, I have to mix up polarity in some place. This applies even to smallest projects, like this one. Took some effort, but I managed to do it, and one of the PSUs is upside down, causing reverse polarity on the half of the board. ESP32 came prepared though, it shorts power in that case, so no damage was done luckily. As a quick remediation, I re-soldered PSU back-side of the PCB thus fixing the issue. So, it is there, but it is on the back side of the PCB.
