F4 2-3S 20A AIO FC V1 is specifically designed for HD VTX, utilizing 2-3S batteries for enhancing the flight experience.

It features a dual BEC solution that delivers stable power outputs of 9V@2A for DJI O3 and 5V@3A for external devices.

With a 20A ESC, it enables agile flight and increases dynamic. And connector for DJI O3 HD VTX and USB port for easy installation

and maintenance. Ideal for HD VTX whoop enthusiasts, offering a heightened level of professionalism and convenience with this FC option.

Bullet Points

• Designed for HD VTX, it features a dual 9V@2A for DJI O3 and 5V@3A for external device BEC solution

• to prevent screen blackout on the DJI O3 due to low voltage during throttle increase.

• It includes a new DJI O3 6-pin PMU for easy installation without soldering, reducing assembly complexity. Newbie friendly.

• The power range of 2-3S provides increased thrust and improved control with a 20A ESC featuring a single NMOS for continuous current capability.

• The upgraded onboard receiver allows selective power cutoff for saving power and offers additional UART TX3 and RX3 ports for connecting the external device.

• Redesigned solder pad layout ensures larger, more secure pads for easy and reliable soldering, while the relocated USB port at the rear facilitates computer tuning.

• It features an STM32F405RGT6 chip, Integrate Serial ELRS 2.4G receiver, 16M black box, barometer, current meter,

• reserve 3 complete serial ports and a standard SBUS, support GPS, HD VTX, external receiver, and other equipment.

Comparison

We upgraded the FC from F4 1S 12A AIO FC V3 to F4 2-3S 20A AIO FC V1. The upgraded FC features an ESC with a

pulse overcurrent capacity of 25A, ensuring stable operation of the flight controller even in the event of motor stalling.

The addition of a 9V 2A BEC power supply ensures the stable operation of the DJI O3 HD VTX when the battery voltage is low.

It also includes a DJI O3 6-pin PMU allowing for connection to HD VTX without soldering.

It integrates features such as a 16MB black box, with support for GPS, external receivers, and other devices.

The redesigned solder pad layout and USB connector make installation and maintenance easier and more convenient.

Note: If you use the F4 2-3S 20A AIO FC V1, the serial port of the SBUS receiver is UART5 while F4 1S 12A AIO Brushless FC V3 is UART6.

F4 2-3S 20A AIO FC V1 also has extended the USB port to the end for easier parameter adjustment and wiring.

And a new DJI O3 6-pin PMU has been added for convenient installation and maintenance.
