The Gerbers (Yup... you can get your own boards pretty quick & cheap)
(Still working on this page... Been a long week...)
W00t! Boards are here!
(Front).jpg)
(Back).jpg)
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...)
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.
