OOPS!: The symbol & footprint currently in use has an error. The M3 does not break out GPIO13... It breaks out GPIO12. (One of these days, I'll get around to correcting that. For now, GPIO13 is actually GPIO12... :( )
This board carries the ESP-M3 module.
The Gerbers (Yup... you can get your own boards pretty quick & cheap)
NOTE: If using PCBWAY for production, the size for these boards needs to be input as 61mm x 36.6. If you use a slightly different (slightly rounder) number, they will charge you a dollar to change it. Just so you know.
W00t! Boards are here!

0.17V on Vcc seems wrong...
Think I'll go ahead and suspect the connector isn't on there quite right. Real bitch to hand solder.
Feeding it 5V directly works just fine...
Just had to add flux & stick the tip of my iron under there to carefully reflow pin 1 of the USB connector.
Notice that I had to take that picture with lots of shade so the LED would show up... :(
(10K at R2 may be a little bit of over-reaction to typical Chinese indicator LEDs...)
In fact, I tried 2K2 on the second board. This is also good...
At this point, the board is fully populated.
Not enough hands to catch the bootup blink of the M3 in the picture, but it did flash.
At this point, tomorrow evenings project is to mount this with a CH340 or CP2102 module to a protoboard & finish testing.
Well... Off by a day, but I built the programming adaptor.
Tho... I suppose it'd be an idea to actually flash something to it & fully prove the point.
So:
esptool.py erase_flash
Followed by:
esptool.py write_flash -fs 1MB -fm dout 0x0 tasmota.bin
and...
At this point...
I do believe the appropriate expression is:
YIPPEE!
