Betaflight is flight controller software (firmware) used to fly multi-rotor craft and fixed wing craft.
This fork differs from Baseflight and Cleanflight in that it focuses on flight performance, leading-edge feature additions, and wide target support.
As you might have learned from the Betaflight GitHub page, our next release will be 4.0. Betaflight 4.0 will be the culmination of years of work that started in 2016 with the introduction of remappable resources, and it will drastically change the way how Betaflight is built and distributed. To you as the user, not much in how you download and install the Betaflight firmware will change, but you will get some noticeable improvements:
we’ll have to spend less time on maintaining and releasing the firmware, meaning that we’ll have more time to work on new and exciting features;
manufacturers will have an easy way to release custom configurations for all of their boards and ready-to-fly (including RX setup and tuning) craft based on original Betaflight firmware - you will no longer be stuck on using old firmware, or recreating your configuration from scratch;
the tinkerers amongst you will be able to share Betaflight firmware with your home built improvements amongst your friends without having to build and distribute separate targets for everybody’s board.
(These changes are planned for F4 and F7, F3’s flash space limitations mean we won’t be able to fit all of this in.)
We are almost there with the implementation of these changes, but since they are quite complex, and getting ‘almost there’ doesn’t buy us much, we have decided that we need to take more time to complete them, make sure the way users can use the firmware still works as expected, and properly test the new firmware. For this reason we have decided to postpone the planned release date for Betaflight to 01 April 2019. We will keep doing monthly releases of Betaflight 3.5 with bugfixes and new / updated targets in the meantime.
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)
DShot (150, 300, 600 and 1200), Multishot, and Oneshot (125 and 42) motor protocol support
Blackbox flight recorder logging (to onboard flash or external microSD card where equipped)
Support for targets that use the STM32 F7, F4 and F3 processors
PWM, PPM, and Serial (SBus, SumH, SumD, Spektrum 1024/2048, XBus, etc) RX connection with failsafe detection
