Yep. Same here but dramatically lower quantities. Was told basically we'd have to pay for a partner's support. Not that I'm expecting better from Arduino, but the community makes up for it. You Google "dragonwing stackoverflow" and there are 604 results, but even the first few aren't remotely relevant. "Atmega328p stackoverflow" is over 14k and relevant. Arduino is 52 million. It's a nonstarter
