Digital ESC firmware for controlling brushless motors in multirotors.
Based on BLHeli_S revision 16.7
Bluejay aims to be an open source successor to BLHeli_S adding several improvements to ESCs with Busy Bee MCUs.
- 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 🎵
- Numerous optimizations and bug fixes
See the project changelog for a list of changes.
Bluejay firmware can be flashed to BLHeli_S compatible ESCs and configured using the following configurator tools:
- ESC Configurator (PWA)
- Bluejay Configurator (Standalone)
You can also do it manually by downloading the release binaries.
See the wiki for documentation.
