1 ![Important Notice: Support for STM32F1 based flight controllers has been dropped in Betaflight release 3.3. This includes NAZE, CC3D (original) and CJMCU like flight controllers](https://raw.githubusercontent.com/wiki/betaflight/betaflight/images/betaflight/stm32f1_support_notice.png)

6 Betaflight is flight controller software (firmware) used to fly multi-rotor craft and fixed wing craft.
8 This fork differs from Baseflight and Cleanflight in that it focuses on flight performance, leading-edge feature additions, and wide target support.
14 | 22 July 2018 | Start of feature freeze / Release Candidate window for Betaflight 3.5 |
15 | 05 August 2018 | Planned [release](https://github.com/betaflight/betaflight/milestone/21) date for Betaflight 3.5 |
16 | 01 January 2019 | Planned [release](https://github.com/betaflight/betaflight/milestone/20) date for Betaflight 4.0 |
20 Betaflight has the following features:
22 * Multi-color RGB LED strip support (each LED can be a different color using variable length WS2811 Addressable RGB strips - use for Orientation Indicators, Low Battery Warning, Flight Mode Status, Initialization Troubleshooting, etc)
23 * DShot (150, 300, 600 and 1200), Multishot, and Oneshot (125 and 42) motor protocol support
24 * Blackbox flight recorder logging (to onboard flash or external microSD card where equipped)
25 * Support for targets that use the STM32 F7, F4, F3 and F1 processors
26 * PWM, PPM, and Serial (SBus, SumH, SumD, Spektrum 1024/2048, XBus, etc) RX connection with failsafe detection
27 * Multiple telemetry protocols (CSRF, FrSky, HoTT smart-port, MSP, etc)
28 * RSSI via ADC - Uses ADC to read PWM RSSI signals, tested with FrSky D4R-II, X8R, X4R-SB, & XSR
29 * OSD support & configuration without needing third-party OSD software/firmware/comm devices
30 * OLED Displays - Display information on: Battery voltage/current/mAh, profile, rate profile, mode, version, sensors, etc
31 * In-flight manual PID tuning and rate adjustment
32 * Rate profiles and in-flight selection of them
33 * Configurable serial ports for Serial RX, Telemetry, ESC telemetry, MSP, GPS, OSD, Sonar, etc - Use most devices on any port, softserial included
34 * VTX support for Unify Pro and IRC Tramp
35 * and MUCH, MUCH more.

41 ## IRC Support and Developers Channel
43 There's a dedicated Slack chat channel here:
45 https://slack.betaflight.com/
47 Etiquette: Don't ask to ask and please wait around long enough for a reply - sometimes people are out flying, asleep or at work and can't answer immediately.
51 To configure Betaflight you should use the Betaflight-configurator GUI tool (Windows/OSX/Linux) that can be found here:
53 https://chrome.google.com/webstore/detail/betaflight-configurator/kdaghagfopacdngbohiknlhcocjccjao
55 The source for it is here:

61 Contributions are welcome and encouraged. You can contribute in many ways:
63 * Documentation updates and corrections.
64 * How-To guides - received help? Help others!
65 * Bug reporting & fixes.
66 * New feature ideas & suggestions.
68 The best place to start is the IRC channel on gitter (see above), drop in, say hi. Next place is the github issue tracker:
70 https://github.com/betaflight/betaflight/issues
71 https://github.com/betaflight/betaflight-configurator/issues
73 Before creating new issues please check to see if there is an existing one, search first otherwise you waste peoples time when they could be coding instead!
77 Please refer to the development section in the `docs/development` folder.
79 TravisCI is used to run automatic builds
