I received the boards today. The quality looks pretty good. I have just one suggestion for the next rev: apply a conformal coating to the front/backside of the boards. The conformal coating would prevent any corrosion from poor air quality. Given the types of environments where the boards operate, I would imagine the air quality isn't very close to ideal.
Overall, it looks like a good product. I'll be putting the board through its paces over the next week.
