F4 Brushed Flight Controller (Frsky Rx + OSD)

  • Sale
  • Regular price $64.99 AUD
  • IN STOCK!


At this time the F4 flight controller is only available with a FrSky integrated receiver.

BetaFPV's F4 brushed Flight Controller heralds in a new era in FPV whoop technology. STM32F411 100MHz high performance MCU, 30A lower resistance MOSFETs, native SPI FrSky receiver, Native Betaflight OSD and reverse polarity protection. 

High-performance ST Microelectronics ARM Cortex-M4 core F411 100MHz CPU (safely overclocked to 120MHz). 

30A continuous drain current MOSFET. Lower to 8.5mΩ inner resistance value (4.5V). It has a noticeable power improvement in low battery voltage status or with 8x20/8.5x20 motors.

TX1 is available for VTX control (Smart Audio).

  • Six-Axis: MPU6000
  • ESC: All FETs are rated at 30A maximum. Supports 6x15mm/7x20mm/8x20mm/8.5x20mm etc motors.
  • Size: 26mm x 26mm, fully compatible with the Inductrix quad frame and mounting pattern
  • Firmware version: Betaflight MATEKF411RX 3.4.0
  • OSD: Built-in BetaFlight OSD (STM32 controls OSD chip over SPI in DMA mode)
  • Receiver: SPI Frsky D8 protocol (FrSky_D), Frsky D16 (FrSky_X) if flashed to Betaflight 3.4.1
  • Power Cable: 55mm, with JST-PH 2.0 connector, AKA PowerWhoop connector
  • Weight: 3.7g 

      BETAFLIGHT OSD

      Betaflight OSD (on screen display) is integrated in BETAFPV F4 brushed flight controllers that shows important flight data on your FPV feed, such as battery voltage, current draw and much more. You can even use it as a menu to change your quad’s PID, rates, filters and other settings. 

      There is a video in and out on the fc itself, labeled CAM and VTX as show below. There should be a video in and out on the AIO camera.

       

      STATUS LED

      There are 3 LEDs on the bottom of the board to indicate the status, including Receiver LED ( Green), FC Status LED ( Red ) and FC Power LED ( Blue ).

      SPI Frsky Receiver

      In Betaflight Configuration, it should be set as FRSKY_D receiver (aka Frsky D8 mode) or FRSKY_X receiver (aka Frsky D16 mode) in SPI RX mode.

      Only use Frsky D16 mode in Betaflight 3.4.1 and up.

      BINDING PROCEDURE

      • Power on the board, either by connecting the battery or USB power. Then the green receiver LED start to flash.
      • The second step, click the bind button for 3s. Then the green receiver LED will be solid on. This means that the receiver is in bind mode and you could start to bind your radio transmitter.

       

      ASSEMBLY

      The mounting pattern of this board is compatible with all the Tiny Whoop airframes, like the original stock Blade Inductrix frame or the Beta75 75mm frame. For other frames like Eachine E010 or E011, a little bit modify is need.
