F4 Brushed Flight Controller (SPI FUTABA RX + OSD)

Here is a review video made by Mr ShutterBug. (The FC that Mr Shutterbug reviews is the original version, the position of the BOOT pad is different from the latest version) A smooth and thrilled flying in the forest and detailed explanation of F4 brushed fc. 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 8.5mΩ 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. You could change VTX settings such as channel and output po
