7-Nano V2 Controller Description:
Compact Size | High-Integration Design
CUAV 7-Nano V2 features a highly integrated laminated design, about the size of a coin, and weighing only 33g. Its compact structure allows it to fit easily into space-constrained platforms such as FPV drones or microcoaxial 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 I H7 High-Speed Processor
Powered by the STM32H753 high-speed processor, it supports secureboot and secure firmware updates. With a 480 MHz double-precision floating-point unit and 2MB Flash memory, it is compatible with PX4and 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 singlesensor malfunctions. This effectively enhances device reliability and faulttolerance, 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.
Enhanced Precision I OCXO Clock
The 7-Nano V2 sensor is equipped with a high-precision temperature control crystal oscillator clock, which significantly reduces ODR error and improves output stability, enhancing system sensitivity and synchronization.
Multi-Mode Adaptability Flexible PWM Output Switching
Supports software-switchable 5V / 3.3V PWM output. The 3.3V PWM offers better peripheral compatibility, while 5V PWM effectively reduces signal distortion and attenuation caused by line loss and interference, ensuring smooth operation of motors, servos, and other actuators for improved flight stability and safety.
Al Computing Support 100M Ethernet Interface
Integrates an Ethernet PHY interface for connecting on-board computers,optical gimbals, data links and more. It provides high real-timeperformance and large bandwidth for intelligent Al applications such asdrone swarming, visual navigation and tracking.
7-Nano PDB Included Wide-Voltage High-Current Input
7-Nano PDB power distribution board integrates voltage/current sensing and power distribution. It supports input voltages up to 70V (3-16S), current sensing up to 60A, and six power distribution outputs. Factory-precalibrated, it delivers accurate voltage and current readings without user calibration.
Ecosystem Compatibility Supports ArduPilot & PX4 Firmware
Compatible with ArduPilot and PX4 firmware, supporting a wide range of unmanned systems, including multirotors, fixed-wing aircraft, VTOL, unmanned ground vehicles, unmanned surface vessels, and underwater vehicles.
