Pixracer Pro

Background/History of the Product:

4 years after the original Pixracer was designed and proven, we recognized the need to bring the design to the forefront of open-source flight controllers. With the Pixracer Pro, we maintained everything that the community loved about the original Pixracer (R15) and improved every deficiency that was known. The resulting fight controller is destined to become the new go-to flight controller for developers and a rock solid foundation for commercial and industrial systems.

Extra Features

Pixracer Pro has a built-in buzzer.


3D Model

Dshot capability

All motor/servo outputs are Dshot and PWM capable. However, mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs. The output groups that must be the same (PWM rate or Dshot, when configured as a normal servo/motor output) are: 1/2/3/4, 5/6, and 7/8.
