Product overview
The CUAV 7-Nano V2 Intelligent Controller provides flight-control hardware for compact unmanned platforms, with ArduPilot and PX4 firmware compatibility. Its laminated construction measures 30.5 x 25.5 x 31.8 mm and weighs 33g, making it suited to installations with limited internal space, including FPV platforms and micro coaxial helicopters. Side-exit wiring supports installation around the compact housing. Processing comes from an STM32H753 Arm Cortex-M7 running at 480 MHz with 2Mb Flash, alongside support for secure boot and secure firmware updates.
The sensing architecture combines dual industrial-grade IMUs with automatic failover, an IIS2MDCTR electronic compass and BMP581/ICP-20100 barometer specifications. The compass offers a dynamic magnetic field range up to ±50 Gs and integrated temperature offset compensation, while the sensor clock uses a temperature-controlled crystal oscillator. Integration options include software-selectable 5V / 3.3V PWM signals and a 100M Ethernet PHY interface for on-board computers, optical gimbals and data links. Supported software features include IMU temperature learning, non-GPS navigation, FFT filtering and LUA scripts.
The supplied configuration includes a 7-Nano V2 PDB combining power distribution with factory-precalibrated voltage and current sensing. This board accepts input up to 70V (3-16S), senses current up to 60A and provides six power distribution outputs. These PDB ratings are separate from the controller's 4.5 ~ 5.5 V operating supply, 4.75 ~ 5.25 V USB supply and 0 ~ 10v servo voltage specification. Installation must also accommodate the specified -20 ~ 85 °C operating temperature and 5 ~ 95 % non-condensing humidity range.
