Excelent quality.
Engineer
I'm so happy with how this turned out my first self-designed flight controller, fully assembled by PCBWay, and the quality is incredible! Every component was placed accurately and soldered cleanly, no defects, no rework needed. I powered it up and tested it thoroughly, and everything works perfectly right out of the box. PCBWay sponsored this project, and their assembly service made it possible for a hobbyist like me to bring a real, functioning board to life without needing my own soldering setup. I'm from Sri Lanka, and I highly recommend PCBWay's assembly service to anyone here — fast, reliable, and genuinely great quality. Thank you, PCBWay! 🚀
