7-Nano V2 Controller Description

Compact Size | High-Integration Design

7‑Nano V2 features a highly integrated laminated design, about the size of a coin, and weighing only 33.8g. Its compact structure allows it to fit easily into space‑constrained platforms such as FPV drones or micro coaxial helicopters. Despite its small size, it offers a rich set of functional interfaces with side‑exit wiring for easy installation, meeting most expansion needs.

Powerful Core | H7 High-Speed Processor

Powered by the STM32H753 high‑speed processor, it supports secure boot and secure firmware updates. With a 480 MHz double‑precision floating‑point unit and 2MB Flash memory, it is compatible with PX4 and ArduPilot drivers and features such as IMU temperature learning, non‑GPS navigation, FFT filtering algorithms, and LUA scripts, providing ample room for future development and new drivers.

Reliability Foundation | Dual-Redundant IMU Design

Equipped with dual industrial‑grade IMUs in a redundant configuration, it supports automatic failover, ensuring stable operation even if a single sensor malfunctions. This effectively enhances device reliability and fault tolerance, delivering smoother performance and safer flights.

Improved Interference Rejection | New Electronic Compass

Equipped with a new electronic compass, it delivers a dynamic magnetic field range of up to +50 Gs, providing significantly enhanced anti‑interference compatibility. Integrated temperature offset compensation ensures accurate positioning even in complex environments.
