3DR Cuby Carrier Board 1 for Control N1 (CN1)
by 3DR

The 3DR Carrier Board 1 for Control N1 (CN1), affectionately codenamed "Cuby" (Model R0026), is a compact, square form-factor expansion platform designed to unleash the full structural and computational capabilities of the micro-scale Control N1 autopilot. Leveraging over a decade of continuous avionics design, the Cuby is uniquely engineered for space-conscious, grid-based, or clustered installations where structural consistency, uniform surface mounting, and tight footprint management take priority over longitudinal length. Its square geometry provides a highly predictable hardware block that integrates flawlessly into standardized enclosure panels, multi-unit server arrays, central industrial control boxes, and multirotor drone frames.

The Cuby serves as a robust plug-and-play intermediary, translating the ultra-dense board-to-board micro interconnect on the Control N1 into heavily isolated, industry-standard peripheral breakouts. It features comprehensive onboard connectivity including 12 native JST-GH locking connector ports covering dual GPS inputs, telemetry radios, dual independent CAN lines optimized for DroneCAN, external SPI, and dual I2C channels. A built-in USB-C interface ensures seamless ground station interaction and diagnostic log retrieval. Power management is simplified down to a single 5V line that cleanly delivers power to the main processor and secondary external sensors alike, while its unpopulated pad system breakouts support up to 12 bi-directional PWM actuator channels for custom multi-servo configurations.
