Revision as of 22:22, 15 October 2020
This is the one that started it all...
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)
This is gonna be a little bit fiddly...
Here's the first attempt at the truly fiddly bits...
Shall we see if it lives?
Nope :(
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.
Semi-w00t... Feeding it 5V directly works just fine...
Full-w00t... Just had to add flux & stick the tip of my iron under there to carefully reflow pin 1 of the USB connector.
It IS, in fact to do SMT work with normal gear...
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...)
Much better. 4K7 it is...
Ready for the next test.
At this point, the board is fully populated.
It's Alive!!!
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.
