Description

Four 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 known deficiencies. 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.

About IO coprocessors

Historically, microcontrollers mounted on Autopilots didn't have enough resources to handle the requirements that industry was demanding. Usually, the features needed to keep up with the trends, pushed manufacturers to add IO coprocessors to increase the number of available timers to generate and decode PWM signals and additional IO Pins. The coprocessor in these hardware architectures is usually connected via a single serial port, reducing the amount of data available in time and introducing more points of failure. However, later generations of hardware have increased IO pin density, timers and reduced size factor, among other enhancements. Additionally, a special benefit also stands out for our design principles, and it is the higher amount and more sophisticated DMAs that work really well with peripherals, transferring high amounts of data and decreasing CPU usage. Besides, we are transitioning from a single MCU architecture to more distributed systems thanks to DroneCAN and Ethernet connectivity (coming soon).
