-Hi there,

After the article published last week about HACK we decided to add in some features, some of which were suggested in the comments, like:

1. another GND pin, so to have ground on both sides of the breakout
2. correct controlled-ish impedance USB traces (Atmel suggests that since traces length in this applications is not significant, impedance for USB traces is not critical anyway)
3. Cortex Debug connector on top side, to easily flash the bootloader (without having to fiddle with the Atmel ICE "squid" connector)

Moreover, while talking with Anool we thought that we could try to shrink the layout at its limits, and voilà! You can now find HACK/small branch on Github, where you will find a PDIP-28 Wide (0.6 " spacing) version of HACK!

Stay tuned for news.

Cheers,

Mick
