BETAFPV F722 35A V2 AIO ICM42688 F722 Flight Controller 35A BLHeli_S 4in1 ESC 2-6S 26X26mm for FPV Freestyle Toothpick Drones

 

F722 35A AIO Brushless Flight Controller is very reliable to meet your advanced FPV needs. Comes with an F722 chip this board provides a great performance capability and high processing speed, which brings pilots a stable and smooth flight. Featuring a 6-pin plug&play port, it can directly connect HD Digital VTX with NO soldering work. With the support of up to 6S input voltage, this FC pushes FPV racer to the max. 

Bullet Point

  • 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.

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°.
