Got my PCB made this week. Anyone else working on a reference build? Would love to compare notes  Smiley



I'm in 1 chip testing now.

It works with my Raspberry pi.

nice job!
could you show assembled board? both sides? would be interesting to see your cooling solution.

I taked picture before sending command to A1.
(It can't be running without heat-sink.)

I attached 55mm fan(with heat-sink assembly) to the bottom of PCB and attached to 50mm Heat-sink top side of asic( using 3M cooling pad. )

I consider Peltier cooling for this summer.

And where would you find 12x12 mm peltier ? Though 15x15 mm exists... Beware of condensation !
