About pixracer pro

Hello Guys. I will buy myself a PixRacer Pro. But I’m not sure if I have the right ESC’s. Can I use Dshot1200 BL_Heli32 Escs with PX4? Thanks for your help.

There’s initial experimental board support for the pixracer pro, but it needs thorough testing/review. https://github.com/PX4/PX4-Autopilot/tree/master/boards/mro/pixracerpro

As for DShot, I’d probably start at DSHOT150 or DSHOT300 which are already more than fast enough for typical loop rates.

What do you mean by Typical loop rates? Can you explain it more please. Thanks. @dagar

DSHOT300 is 300,000 bits/second and each ESC command is 16 bits (11 bits throttle + CRC + telem request). 300,000 / 16 = 18.75 kHz ~= 53.3 microseconds/command. Even at a loop rate of 4 kHz (IMU_GYRO_RATEMAX 4000) which is 250 microseconds per iteration, DSHOT300 is plenty fast enough.
