DShot1200 ESC Protocol

What is DShot1200? DShot1200 is an ESC protocol similar to DShot 600, but twice as fast with lower delay. There are some benefits in using DShot1200, and special hardware is required to run it.

To learn about what DShot is please see this guide.

Just like DShot150, DShot300 and DShot600, the number “1200” in DShot1200 signifies the bit-rate in kilobits per second. So in theory DShot1200 is 2 times faster than DShot600.

DShot1200 would be faster than Multishot too. Multishot has a varying signal length between 5us to 25us depends on throttle level, while DShot1200 has a constant, fixed signal length of about 13uS. Unless you fly really slow with Multishot with low throttle, it’s more likely that the delay would be between 15us to 25us (50% to 100% throttle).

Advantages of DShot1200

Comparing to Analog ESC protocols like Oneshot and Multishot, the same benefits of DShot applies to DShot1200:

  • Higher resolution and more accurate and reliable data
  • Data error rejection
  • Now with the advantage of even higher speed with DShot1200, there are more reasons to change over to digital ESC protocol now from analog

Comparing to other DShot protocol, DShot1200 is simply faster. And faster is always better if the system is capable of running it :)

What ESC/FC can run DShot1200

DShot1200 has been implemented and tested in KISS FC and ESC’s. And we are hoping it will be available for Betaflight and BLHeli in the near future too.

Any ESC that is already struggling with DShot600 will not be able to run DShot1200. I think the latest 32-bit ESC’s with STMF0 processors and BLHeli_32 firmware should support DShot1200 when they are out.

    How fast/what is the update freq. of value sent from RC transmitter through RC receiver to Flight Control board? Assumimng some fast serial protocol like FrSky SBUS.

    If DShot1200 has update freq of 83kHz what is max. update freq. in Betaflight with best/fastest FC in these times?
