First prototype PCBs arrive
8 Channel PCBs arrived yesterday from China. Parts are behind schedule so I am in a holding pattern. A few days I suspect. I’ve written the Bluetooth firmware though, so that part is tight. I will be doing prototyping this weekend I suspect and should have an idea how close I got on the first go around.
The photos below show both boards separate and stacked. The board on the right uses very heavy copper and I will likely double it again after thorough testing.
