# Overview
The NW Blue PROH757 is a professional grade autopilot that is equipped with the robust processing power of the CubePilot Orange+ through the use of the CubeNode™. With automotive grade components and the proven industry track record of CubePilot, the NW Blue PROH757 autopilot is tiny but mighty and ready to take on the most critical of missions.
As a compact, high-performance flight control platform the NW Blue PROH757 was designed for professional UAV systems, Mission systems, and research applications. The autopilot is built around the STM32H7 series processor and integrates a complete set of sensors, high-speed interfaces, and power management features required for modern autonomous flight systems. The architecture was designed for compatibility with leading open autopilot ecosystems including [ArduPilot](https://ardupilot.org/), [PX4](https://px4.io/), [Betaflight](https://www.betaflight.com/), and [INAV](https://github.com/iNavFlight/inav).
The autopilot integrates a precision IMU subsystem, magnetometer, barometer, and high-speed data interfaces while maintaining a compact 36 × 36 mm footprint suitable for both aerial robotics and embedded navigation systems. The autopilot includes onboard microSD logging, USB-C connectivity for configuration / firmware updates, and CAN bus connectivity for DroneCAN devices.
Robust electrical design practices were incorporated throughout the PROH757 autopilot. External signal lines are protected with low-capacitance ESD diode arrays, and series impedance control is applied to high-speed and externally exposed signals. Power rails include local filtering and monitoring circuits for system voltage, 5V rail, 10V rail, and 3.3V supply, enabling firmware-level health monitoring of the power system.
The six-layer PCB stack-up was optimized for signal integrity and EMI performance. Dedicated ground and power planes provide low-impedance return paths and stable sensor operation, while switching power circuitry is isolated from sensitive analog and digital subsystems.
The NW Blue PROH757 Autopilot, *powered by CubePilot,* is intended for integration into professional UAV platforms, robotics systems, mission systems, and advanced flight control research where reliability, expandability, and compatibility with established flight control firmware are required.
