Optimized Title: BETAFPV Serial ELRS F4 2-3S AIO Flight Controller for 2-3S HD Digital Quadcopter

The F4 2-3S 20A AIO Brushless Flight Controller is a versatile and feature-rich unit designed for HD VTX applications. It boasts a dual BEC solution, offering 9V@2A for the DJI O3 and 5V@3A for external devices, ensuring a stable power supply and preventing screen blackouts during high-throttle maneuvers.

One of the standout features of this flight controller is the inclusion of a new DJI O3 6-pin PMU, which allows for easy installation without the need for soldering, reducing assembly complexity. The redesigned solder pad layout ensures larger, more secure pads for reliable soldering, while the relocated USB port at the rear facilitates computer tuning, making it a newbie-friendly option.

The power range of 2-3S provides increased thrust and improved control, thanks to the 20A ESC featuring a single NMOS for continuous current capability. The upgraded onboard receiver allows selective power cutoff, saving power, and offers additional UART TX3 and RX3 ports for connecting external devices.

Under the hood, the F4 2-3S 20A AIO Brushless Flight Controller is equipped with an STM32F405RGT6 chip, an integrated Serial ELRS 2.4G receiver, 16MB of black box storage, a barometer, a current meter, and three complete serial ports. It supports SBUS, GPS, HD VTX, and various other external equipment, making it a versatile choice for a wide range of applications.

The package includes the flight controller, M210 machine screws, M210 nylon screws, M2 nuts, shock-absorbing balls, JST1.25mm angle and straight sockets, a SH1.0 4-pin adapter cable, a Type-C to SH1.0 adapter, an XT30 power cord, a filter capacitor, and VTX connector wires.

In summary, the F4 2-3S 20A AIO Brushless Flight Controller is a feature-packed and user-friendly option for HD VTX applications, offering a robust and reliable solution with a range of connectivity options and power management capabilities.
