20*20mm HAKRC F7220 40A 2-6S Flight Controller AIO BL_32 w/ 5V/3A 10V 2.5A BEC for FPV Racing RC Drone Precise details: Features: 1. PCB adopts high-end 8-layer 2oZ thickened copper skin, which has stronger overcurrent capability and good heat dissipation. 2. MOS adopts imported 40V high current resistance MOS, long life with strong load capacity. 3. Adopt industrial grade LDO, high temperature resistance. 4. Using high-quality Japanese Murata capacitors, strong filtering performance Size: 40*30mm (20mm-20mm mounting hole) Packing size: ø64*64*35mm Product net weight: 10g Package weight: 44g Flight controller parameters: CPU:STM32F722RET6 IMU:ICM42688 OSD:AT7456E Barometer: integrated Black box: 16M BEC:5V/3A BEC:10V/2.5A Uart : 5 LED: Adjustable LED light Sensor: Built-in current sensor Firmware version: HAKRCF722D Receiver: Frsky/Futaba/Flysky/TBS Crossfire/DSMX: DSM2 receiver Ø ESC parameters: Firmware version: HAKRC_AT4G_Multi_32_9.Hex Protocol support: PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, Dshot600 Input voltage: 2S-6S Lipo MOS Model: 7140 PWM:24-128K Continuous current: 40A Peak current: 45A Note:After upgrading the firmware of hakrc f4126aio,the sensor direction needs to be changed 1.Connect FC to BF and select “configuration” page. 2.In the “flight control and sensor direction” column on the right side of the configuration page, change the first gyroscope to cw 90 3.on the setup page. Calibrate the flight control accelerometer and reset the z-axis and test whether the flight control roll, pitch and yaw are consistent with the BF feedback direction. 4.please check and make safety preparations before takeoff in an open or relatively safe place to test the flight feasibility.
