Control N1 (CN1) Autopilot Module – World’s Smallest High-Performance Flight Controller - R0024

Control N1 is the world’s smallest, lightest, and most versatile high-performance autopilot module. Weighing just 2.38 g and measuring 17.6 × 28.15 mm, it delivers ArduPilot and PX4 compatibility in an unbelievably compact footprint.

Powered by an STM32H743 processor with advanced sensor fusion, the CN1 brings commercial-grade flight control to even the most space- and weight-constrained UAV and robotics platforms.

Built on over 10 years of flight controller design and development experience.
