Digital ESC firmware for controlling brushless motors in multirotors.

Based onBLHeli_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 projectchangelog 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 therelease binaries.

See thewiki for documentation.
