Wow that was fast . Its about 4.5 by 4.5 and for the short run it 3 for 180. Know its expensive but had to try. Have a simpler design that just breaks out the top pins that was about 3 for 50. Parts are the cheapest probably around 20 - had a lot of pieces laying around. Proabably could be cheaper because like I said I had no idea what I was doing and I added a lot of pin breakouts.
Sounds good. Pictures?
I have good luck with OSHPark who are reasonable with their prices, especially for smaller boards. My guess is digistump (https://pcbs.io/), the prices would be lower. But recently their website showed they were for sale and now it does not. So not sure if it was sold... Their price is sliding from $4-$3 per square inch. Over 20 square inch is $3. so at 16 square inch, my guess is maybe $3.50 per sq inch would be about $56.
Paul mentioned a proper way for debugging, integrated into the Arduino IDE, is on his to-do list. Maybe this will use JTAG as well?
You may know, but the 5V pin is connected to the TPD3S014 power switch and it's off by default.In particular, if I am powered only by USB, I don't want the board to feed the +5v to the Host connector pins.
Recommendation for which Diodes you like using?
Thanks Kurt. Got it redesigned but am going to hold off on shooting the order off. I'll wait and see if there are any other thoughts out there.
Thanks again
Mike
