Introducing C1 MICRO USB camera

Tiny and lightweight camera system based on original C1 was in development for a while. It was challenging to squeeze all components even to 6 layer PCB with tight tolerances. After a few design iterations finally, C1 MICRO M12 camera is released and pre-orders are open.

Key features

  • Lightweight and small. Camera weight without a lens is only 12.6g
  • Modular design to fit various lenses
  • Shrouded 5 pin connector to save space and for easier integration
  • Aluminum case for efficient heat management
  • Low 80-200ms latency video transmission
  • Onboard h.264 / MJPEG / YUYV video compression
  • Unique serial numbers for easier identification in multi-camera setup

What is different from original C1

C1 MICRO platform was built for tight integrations where space and payload capacity is limited. It can be kitted with M12, CS and D14 mounts for different lenses. Connectivity was updated with space-saving WR-WTB 1.00mm male vertical shrouded header instead of Micro USB.

Lens mount options

C1 MICRO PCBA is designed to fit standard M12 lens housings with 20mm spacing between screws. Kurokesu lens housings are precision CNC machined and have registration features so after assembly optical axes align with tight tolerances. Also will be available for CS and D14 lenses.


C1 MICRO offers USB 2.0 interface over small 1.0mm pitch connector. The signal layout is mapped in the diagram below.
