💡 Why ochin?

ochin_cm4v2 was created by a hardware designer passionate about compact embedded systems.
It was born from real-world needs in the OpenHD drone community — for a carrier board that was smaller, tougher, and more power-friendly than standard options.

If you need a CM4 baseboard for mobile platforms, low-latency video, or embedded integrations — this is for you.
