Production heatsink is 83x100x40mm.
Board dimensions:
https://www.dropbox.com/s/gkuayv84tr63x70/BitBurnerXX_rev3.pdfI could provide a iges/step files of the assembled board if that helps.
Todays status: Found a nasty bug that produced the flood of nonce errors.
And I fried one part of that chip that i planned to replace tomorrow. - just another reason to change it.
But it meant that i could only run it with one chain today.
It was pretty stable though, about 2% HW errors.
But with the replacement chip that should hopefully go down to 0%.
And then I can pull the trigger on the website and the PCB Orders.
