the WLEDnano is a ESP32-S3 mini controller board with USB-C power and flashing. It is around 1 in by 1 in in size.

I'd guess you need a cap on U6

I do.

Where

#

Should be right by chip

It's on the bottom side of the PCB.

Too far

#

And big

#

But may fit left of chip

Good to know. I didn't think it mattered.

It's to mitigate chip noise

I originally had the U4 on the bottom, but moved it to the top so I could use a reflow plate.

But I think there could be some cool uses for this board, like making light up clothes. And it's like the size of a XIAO board. But like the only place you can get the ESP32-S3-MINI-1 is from parts distributors.

there's some nice boards using this mini esp32 - some of them even omit the USB port to make them extra small
