Item name: F4 V3 PLUS Flight Controller Firmware: OMNIBUSF4SD Size: 36x36mm Mounting holes: 30.5x30.5mm STM32 F405 MCU Dshot support Drag and Drop OSD configured via Betaflight BMI270 6 axis SPI gyro & accelerometer SBUS / PPM AND Spketrum DSMX ports MicroSD card blackbox Baro (BMP280) 5v3a 9V3A BEC On-board video filters (only 5V to VTX and camera) Boasting a F4 processor, on-board Betaflight OSD, MicroSD Black Box, 5v3a sbec, video filter, you'll be tuning pids with your transmitter and Tear it to the track in no time! Note: 1. The F4 V3S Plus Flight Controller only support Betaflight software, and we do not suggest to adjust the parameters. 2. There are two kinds of flight controller board, we will ship it at random. F4 Pro V2 Description: This is the all new F4 Pro, based on the design of the popular F3 pro. However this main advantage of this board is that is uses the more powerful STM F4 processor for even faster loop times. It has all the other things you love from the Omnibus F3 pro including an OSD module, SD card reader, low noise IC268G IMU connected via SPI, a current and voltage sensor etc.. The V2 Pro version now includes a built in BEC , so you can power this board directly from your flight battery (up to 4s) Specification: SPI Gyro IC268G On-Board OSD (controllered by Betaflight, FC over SPI bus) MicroSD Blackbox Baro (BMP280) (default is closed,need to open in configuration,if not know how to open, contact with us) F4 Processor (F405) 5v3a SBEC Built-in Current Sensor On-Board Video Filter (only can supply 5V to VTX and Camera) USING PPM If you have trouble geting the FC to recognise your PPM receiver, here is what you need to do. You need to enable RX_serial in the GUI and turn UART3 on. Save and reboot the flight controller. Then re-selecting RX_PPM again on the GUY and the FC now communicates with your PPM receiver Package included: 1 * Omnibus F4 V3 plus Flight Controller new F4 V3. LC image filter
