BETAFPV F4 brushed FC board bring a new era in FPV whoop technology. STM32F411 100MHz high performance MCU, 30A lower resistance MOSFETs, SPI Frsky Rx, Build-in Betaflight OSD and polar reversed protection. All of these is backed by the same reliability and warranty of all BETAFPV FC boards.
High-performance ST Microelectronics ARM Cortex-M4 core F411 100MHz CPU (safely overclocked to 120MHz). Okay, i am the second highest performance whoop board in the world.
30A continuous drain current MOSFET. Lower to 8.5m? 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. You could change VTX settings such as channel and output power in your Betaflight OSD or using your Taranis LUA Script. Here is the diagram when using the TBS Unify PRO Nano 5.8G VTX.
Polarity reversed connection protection. Battery polar reversed connected. Bomb. This issue will never happens.
Key Features
- The world's first compatible BetaFlight OSD, FrSky Rx, BetaFlight firmware, born for acro flight controller for the Micro Whoop or Blade Inductrix quadcopter.
- Fully programmable through Betaflight, using the onboard USB port, tune all the parameters, PID's, and rates to your perfect settings
- Designed to work with current Tiny Whoop or Blade Inductrix setups
- Built in SPI Frsky D16 protocol native receiver, compatible with almost ALL Frsky radios(e.g. Taranis X9D/X9D Plus/X7) or Frsky compatible transmitter module
- The flight controller board comes pre-flashed with Betaflight firmware, and pre-soldered 55mm power cable pigtail with JST-PH 2.0 connector, AKA PowerWhoop connector.

Update of the F4 Brushed Flight Controller (Frsky Rx + OSD)
Since the firmware is the latest Betaflight 3.4.1, SPI Frsky D16 connection works well in this F4 flight controller.
The position of the BOOT pad on the latest F4 Brushed Flight Controller is changed to near the BIND button.
Tech Note: this product uses a built in SPI type receiver and will NOT bind to newer FrSky ACCESS transmitters or those running the latest ACCST 2.0 firmware. It can ONLY bind to FrSky branded transmitters running ACCST 1.0 firmware. It will also bind to Jumper/Radiomaster transmitters capable of transmitting in D16 mode.
