The Cube Yellow F7 Chip-Single Module (Discontinued)

The Cube Yellow F7 is a new Pixhawk flight controller modules in the Cubepilot ecosystem designed for hobby users, commercial system integrators and UAS manufacturers. The Cube Yellow has stronger performance, faster, more secure, built-in triple redundant sensor, temperature control shock absorption IUM.

The Cube Yellow flight controller is a remote controller based on the Arm STM32F7 series SOC. Sitting directly between the Cube Black (Pixhawk 2.1) and Cube Orange, but this model offers better performance and newer sensors over the Cube Black while retaining F series SOC compatibility.

The new generation of more powerful STM32F7 (F7 chip) processor, stronger performance, faster, more secure, built-in triple redundant sensor, temperature control shock absorption IUM.

With the help of flight software, The Cube Yellow is a open source flight controller in Hex Cube flight controller series which can completely fly for any remotely controlled aircraft, quadcopter, helicopter or multi-rotor vehicle and become a more professional uav platform.

Just like the other models the Cube Yellow is part of a wide ecosystem of autopilot modules and carrier boards.

All the Cube models are compatible with all of the carriers which allows users to choose an off the shelf carrier board design that best suits their needs. System designers are able to integrate the Cube directly into their designs via published carrier board specifications.

It is a very efficient Pixhawk flight controller for PX4 users. This product is made in Taiwan.

The Cube Yellow Features

Faster F7 SOC with 512KB ram
Upgraded triple redundant IMU sensors for extra redundancy
2 sets of IMU are vibration-isolated mechanically, reducing the effect of frame vibration to state estimation
IMUs are temperature-controlled by onboard heating resistors, allowing optimum working temperature of IMUs
The entire flight management unit(FMU) and inertial management unit(IMU) are housed in a relatively small form factor (a cube).
Fully Cubepilot carrier board compatible, all inputs and outputs go through a 80-pin DF17 connector, allowing a plug-in solution for manufacturers of commercial systems. Manufacturers can design their own carrier boards to suit their specific needs now and in the future.
