3DR Docs N1

Meet Control N1: the world's smallest, lightest, and most versatile Autopilot Module. At just 17.6×28mm and 2.3g, this tiny powerhouse brings full ArduPilot and PX4 flight control to even the most space and weight constrained designs.

Key Features

• Ultra-Compact & Feather-Light - Barely bigger than a stamp—17.6×28mm and under 2.5g, the CN1 integrates into small UAVs, ROVs, UUVs, and custom robotics platforms without compromise.
• High-Performance Core - Powered by an STM32H7 MCU, it delivers the processing horsepower needed for stabilized flight, advanced mission planning, and real-time sensor fusion—and leaves over 50% of its compute capacity reserved for future enhancements and custom applications.
• Single-Sided design - We've engineered the entire autopilot onto a single-sided PCB—minimizing board area and complexity for effortless manufacturing, faster turnarounds, and lower cost. Simplicity increases robustness ("the best part is no part"), reducing potential failure points and boosting reliability.
• Flexible and Future-Proof Board-to-Board Interface - Designed with the future in mind, our board footprint –similar to a Raspberry Pi CM5 connector type – exposes spare signal pins so you can create future custom controller boards, not just carrier boards—in other words, you can reuse all your existing carrier/main boards and progressively upgrade them at your own pace.
• Real-World Sensor Selection - We didn't pick components on paper alone. Through extensive industry connections and in-field testing, we hand-select only the very best sensors. Expect performance so ahead of the curve that competitors will continue to follow our lead.
• Affordable, US-Made Excellence - Proudly designed and manufactured in the USA, the CN1 undercuts bulkier, heavier-and more expensive- competitors while delivering premium flight-control features—and we don‘t cut corners where people can't see, we only use legit passive and active component brands like Murata, STMicro, Texas Instruments, NXP, and more.
• Open-Source Ecosystem - As our core tradition, we offer full compatibility with ArduPilot and PX4 communities means instant access to mature firmware, mission-planning tools, and global support.
