ITEM NAME:F4 Betaflight F4 Pro V3 RC Brushless Flight Controller Board Built-in OSD Product Description Description: F4 Betaflight F4 Pro V3 RC Brushless Flight Controller Board Built-in OSD Smart Audio Integrated FC for FPV Racing Drone RC Accessories Dshot Support Description: Following in the footsteps of Omnibus F3 Pro, Omnibus F4 Pro V3 could become the standard for measuring all other flight controllers. With F4 processor, onboard Betaflight OSD, MicroSD black box, 5V3A SBEC, video filter, you can pass through emitter and tear it up at once! As programming leaps forward, you can now connect to VTX that supports Smartaudio, for example, use our Omnibus SmartAudio connector to connect TBS Unity Pro 5G8 HV or TBS Unity Pro 5G8 HV-Race Edition to the J10 connector and make VTX dynamic changes through Betaflight OSD. The Omnibus flight controller started with various community projects, and the result was an accumulation of views from the RCgroups forum. Having said that, it's not surprising that they have all the features the FPV community looks for in a top-notch F4 MCU. With support for SmartAudio V2, it feels like every option has been added that can be added without compromising the life of the multi-functional FC. Feature: STM32 F405 MCU. Dshot support. Drag and drop OSD through Betaflight Configurator. Smartaudio V2 support - adjust your PID and configure the Omnibus FC from the transmitter. MPU6000 6 axis SPI gyroscope and accelerometer.
