Minimalist AVR programmer

IMG_5985-1024x682

Philip Peter posted an article describing how he designed his Minimalist AVR programmer:

I always like a challenge, so when I saw [simpleavr]s vusbtiny programmer, I started to wonder how small I could make an AVR programmer. All in all I’m pretty pleased with the result.

The schematic is almost the same as the original one. I only added a LED an resistor to indicate a proper power supply.

    1. Congrats for this small and beautiful design!

      I have one suggestion: could you make the USB cable footprint compatible with an USB A through-hole plug, i.e. a pitch of 2.5/2.0/2.5 mm vs. 3×2.54mm?

      This would not change anything if you solder an USB cable like you do, but it would give you the ability to mount an USB A TH plug on the tiny PCB

      1. Thank you!

        Having the holes match a standard USB A plug is a great idea, and it should be fairly easy to do. I will definitely add that to the next version.
