FASTUSBasp - another AVR programmer (cheapest?)

[ami]

Hello,

This is my first post on eevblog. Glad to join this forum.

 I wanted to create an AVR programmer but with real USB hardware to avoid connection issues which I had with USBasp before.
This uses cheap blue pill (stm32f103c8t6) board.

It exposes usb to serial interface (USB-CDC) as well which could be useful to debug AVR microcontrollers.
