At WCH, we enjoy creating opportunities to learn by doing. 🛠️
We recently hosted the Super-Speed USB 3.0 & 100W PD Hub Innovation Challenge.
Participants redesigned a USB hub PCB, tested real performance, and pushed for smarter, more compact designs.
A great example of collaboration and hands-on innovation. 🤝
