Betaflight is the world's leading multi-rotor flight control software. The FPV drone racing and freestyle community choose Betaflight for its performance, precision, cutting-edge features, reliability and hardware support.

You can use Betaflight to complete firmware upgrade and debugging tests before takeoff (receiver, map transfer, motor, GPS, LED and other functions).

Betaflight supports most manufacturers: STM32F411, STM32F405, STM32F722, STM32H725, STM32H735, STM32H743, AT32F435.

Firmware is the backbone of any ESC; it's the software that breathes life into these components, determining the range of settings you can tweak.

Each ESC firmware is only compatible with certain hardware.

Both are designed for ESC with 8-bit processors and are interchangeable. However, Bluejay is generally favoured for its superior performance, robust feature set and consistent updates.

BLHeli_S: An improved version of the base BLHeli code. Has motor PWM that is synchronous to the MCU master clock (generated by hardware), making the motor silent. Supports very high motor speeds.

Bluejay: BLHeli_S-based firmware capable of bi-directional DShot — a great choice if you want to run RPM filtering on your rig. Aims to clean up and simplify the original BLHeli_S source code.

BLHeli_32 and AM32 are designed for ESC with 32-bit processors, unlocking possibilities that 8-bit predecessors couldn't handle.

Features include ESC Telemetry, customizable startup tones, and support for higher PWM frequencies.

All BLHeli_32 MCUs (F0, F3, F4, G0 etc) support the "ByRPM" feature with Rev32.9 code, and support "any" PWM frequency range (determined by the hardware manufacturer).

If you have a regular setup, just install and go fly. Or configure/update by connecting to your ESCs through the Flight Controller using BLHeliSuite and a USB cable.
