3DR Reference Design Carrier Board for Control Zero H7 OEM G
by 3DR

The 3DR Reference Design Carrier Board is the definitive full-featured development and evaluation platform engineered specifically for the Control Zero H7 OEM (Revision G) autopilot. While ultra-narrow variants compromise on peripheral breakouts to fit tight spaces, this reference board serves as the unrestricted blueprint for enterprise hardware integration. It translates the high-density micro-interconnect array of the Control Zero core into a highly accessible layout, giving aerospace engineers, autonomous vehicle developers, and commercial sUAS manufacturers uncompromised access to every hardware serial port, bus, and signal line available on the H7 processor.

The architecture prioritizes robust, industrial-grade connectivity by utilizing locking, standardized JST-GH connector ports across all primary peripheral stations. The board comes fully equipped with dedicated ports for primary and auxiliary telemetry radios, master GPS modules, I2C sensor expansion buses, and dual independent CAN channels configured for seamless plug-and-play DroneCAN networks. Additionally, a comprehensive array of through-hole pin headers supports expansive PWM actuator and ESC outputs for complex multirotor, fixed-wing, and robotic configurations. Complete with onboard voltage regulation protection, a dedicated safety switch interface, and a direct USB debugging port, this carrier board provides the foundational ecosystem required to safely prototype, validate, and deploy mission-critical autonomous systems.
