Digital ESC firmware for controlling brushless motors in multirotors.

> Based on [BLHeli_S](https://github.com/bitdump/BLHeli) revision 16.7

Bluejay aims to be an open source successor to BLHeli_S adding several improvements to ESCs with Busy Bee MCUs.

## Current Features

- Digital signal protocol: DShot 150, 300 and 600

- Bidirectional DShot: RPM telemetry

- Selectable PWM frequency: 24, 48 and 96 kHz

- PWM dithering: 11-bit effective throttle resolution

- Power configuration: Startup power and RPM protection

- High performance: Low commutation interference

- Smoother throttle to pwm conversion

- User configurable startup tunes :musical_note:

- Numerous optimizations and bug fixes

See the project [changelog](CHANGELOG.md) for a list of changes.

## Flashing ESCs

Bluejay firmware can be flashed to BLHeli_S compatible ESCs and configured using the following configurator tools:

- [ESC Configurator](https://esc-configurator.com/) (PWA)

- [Bluejay Configurator](https://github.com/mathiasvr/bluejay-configurator/releases) (Standalone)

You can also do it manually by downloading the [release binaries](https://github.com/mathiasvr/bluejay/wiki/Release-binaries).
