BetaFPV F722 V2 2-6S AIO Whoop/Toothpick Flight Controller (w/ 35A 32Bit 4in1 ESC) - ICM42688

F722 2-6S AIO 35A FC is a very reliable FC that is made to meet your advanced FPV needs. Comes with an F722 chip and a BLHeli_32 ESC, this board provides a better performance capability and higher calculation speed, which brings pilots a more stable and smoother flight. What's more, F722 AIO FC has specially added a 6-pin connector for DJI Digital VTX, just plug & play, less solder work needed, super easy to install. It can handle 35A continuous current (40A burst), supports the 2-6S lipo battery.

Features

• Built-in STM32F722RET6 CPU, F722 FC is more powerful than F4. It features a fast processing speed and stable performance, providing reliable and smooth flight for 4"-5" drones.
• F722 AIO 35A FC has specially added a 6-pin connector for HD Digital VTX, just plug & play, less solder work needed, perfect for the pilots who enjoy the HD Digital VTX system.
• 6 full UARTs are available on this board. With plenty of UARTS, Pilots could have more options for external parts like VTX, GPS, Receiver, and other components.
• It can handle 35A continuous current (40A burst), supports the 2-6S lipo battery, and gives the drone a more robust flight performance.
• With the 6S battery and this F722 35A AIO FC, the drone will break through the limit of the power of the toothpick drone, exploring more possibilities in 4-5'' drones.
• The new BLHeli_32 ESC version is built-in a 16MB flash memory chip dedicated to Blackbox logging, which is an extremely powerful tool for tuning and troubleshooting an FPV drone. It has a faster processing speed and up to 128k PWM frequency, providing a more stable and smoother flight for pilots.

BLHeli_32 ESC Firmware

The F722 35A AIO FC has two boards with different ESC versions for choice. The V2 board uses AT32F421G8U7 MCU, a 32-bit  ESC chip, with BLHeli_32 ESC firmware. This firmware supports up to 128k PWM frequency, featuring faster processing speed and unlocking more functions for the flight.

Know More About ICM42688 Gyro

The F722 FC ICM42688 version has the same solder pad and layout as BMI270 except for the gyro chip. Besides, you can also find the difference in Betaflight settings.

The ICM42688 gyro supports 8.00 kHz gyro update frequency compared with the BMI270 gyro which supports 3.20 kHz. When using a 6S battery, the ICM42688 gyro has a good performance.

The degree between ICM42688 and BMI270 gyro is different. When configuring F722 FC ICM42688 version, the gyro degree should be set to CW270°.

Diagram for F722 35A AIO FC

The below picture is the top front of the F722 35A AIO Brushless FC. (Both V1 and V2 boards have the same solder pad and connector ports.)

The below picture is the bottom front of the F722 35A AIO Brushless FC. (Both V1 and V2 boards have the same solder pad and connector ports.)

There are 2 LEDs on the bottom of the board to indicate the status, including the FC LED (Blue) and FC Power LED (Red). The LED status for V1 and V2 boards are the same.

How to Connect the External RX&VTX

To connect the external RX&VTX, please refer to the below diagram. F722 35A AIO V1 and V2 boards have the same soldering pad and connecting ports.
