Price update:

1,99 BTC / board

Same price as your first boards but 2 months later. Did u even improve all the quality issues like USB ports popping off the board?

The first boards we shipped had this problem, we fixed it for the rest of the deliveries.

If you order a tower of boards, there might be some boards with this problem among them. This is however no issue because the data is passed through the CAN-BUS.

Think about your prices and then tell again that low qual is a no issue.
