BLHeli is open-source firmware for sensorless brushless motor electronic speed controllers (ESCs), written in assembly for Atmel and Silabs 8-bit MCUs, with BLHeli_S and BLHeli_32 variants. It is flashed onto ESC boards used primarily in multirotor and helicopter applications.
Use cases
- flash firmware onto brushless ESC boards for drones
- configure ESC settings like throttle response for multirotors
- control brushless motors in RC helicopters and planes
- customize motor speed controller behavior for FPV quadcopters
When to choose
- you need open-source ESC firmware for 8-bit Atmel or Silabs ESC hardware
- you want smooth, configurable throttle response for multirotor motors
- you want to flash and tune ESCs using BLHeliSuite
When to avoid
- you need open-source firmware for 32-bit ARM ESCs, since BLHeli_32 is closed source
- you need sensor-based (sensored) motor control
- your ESC hardware is not supported by BLHeli or BLHeli_S
