# Alternative Protocols
In the drone community the standard pwm has become too slow and therefore it has been adapted. It was mostly the update rate which was too slow

## Overview
A good overview page can also be found [here](https://oscarliang.com/esc-firmware-protocols/).

|ESC Protocol|Signal Width|Lowest Update Rate|
|---|---|---|
|**PWM**|1000-2000us|0.5KHz|
|**OneShot125**|125-250us|4KHz|
|**OneShot42**|42-84us|11.9KHz|
|**MultiShot**|5-25us|40KHz|
|**DShot150**|106.7us|9.4KHz|
|**DShot300**|53.3us|18.8KHz|
|**DShot600**|26.7us|37.5KHz|
|**DShot1200**|13.3us|75.2KHz|
|**DShot2400**|6.7us|149.3KHz|
