Nice work!
Greetings to Slovakia from Ukraine! Wink

I have two questions:
- Will this shield be backward compatible with Arduino Uno?
- And what is needed to adopt the shield/rig board to bitfury's chip?

Thanks!

Very very very unlikely: the DUE has an ARM-A3 and communicates at 3.3v compared to the 328's 5v!

ARM-A3:
A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock. (for more information look int type page).
CPU Clock at 84Mhz.
96 KBytes of SRAM.
512 KBytes of Flash memory for code.
a DMA controller, that can relieve the CPU from doing memory intensive tasks.

Whereas an Uno has a 16Mhz 8bit CPU with 16KB of ram.

Loving the work btw, hope you get some bitfury chips! At 0.5w/ghash they look great.

Thanks for the answer!

Bitfury is out of testing chips right now. There's a big boom about this small hulk.
I saw them in my hands, but since I am not a skilled engineer, there were no use for me to take them alone.
But since the project for Arduino is kind of niche market and I like the idea, I will do my best to have the chips, when they will be available.

P.S. You mean, UNO is too weak to serve as a tunnel from ASIC-rig to Host (PC)?
