FC firmware FLASH and Settings FC firmware FLASH 1.Long Press BOOT buttons，connect USB，The system automatically install the driver 2.open betaflight configurator，enter DFU mode Zadig software downloaded to a computer, it is a run file 3.
4.Click the Options, select List All Devices after the diagram below 5.Click Replace Driver At this point automatically to computer load driver.Now open betaflight tuning software, automatic loading good drive, betaflight software will display in the joint the diagram below： 6.
7.Don't open the Settings 8.click “Load Firmware[Local]” Select the firmware “betaflight_3.1.*-3.2-*_OMNIBUSF4.hex”（The firmware version according to the actual situation） 9.click “Flash Firmware”，progress bar “Programming:SUCCESSFUL” Finish! 10.
F4 Flight control parameter Settings 1、FC horizontal ，The acceleration of calibration 2、2.4G sbus receiver:open UART1 RX, IRC TRAMP is UART3 TX, ESC telemetry is UART6 RX, then click “save and reboot”(Each set needs to be saved) Note: click save after will jump to the startup screen, reconnect! 3.
4.Open the voltage current detection 5.Open the ESC_SENSOR, osd, article LED lights set (choose) as required After set up parameters on this page, save the Settings. 6.
7.the OSD Settings, according to the need to choose, drag the OSD schematic diagram of the parameters can be adjusted. 8.LED Strip configuration, set according to need So far, flight control basic setup to finish.
Using The OSD The XJB Micro F4 includes Betaflight OSD, which displays information like battery voltage and mAh consumed while you fly. In addition, the Betaflight OSD can be used to configure the quadcopter, making in-field adjustments and tuning more convenient. MODE2 MODE1 The graphics above show the stick command to bring up the OSD menu. The stick command is: throttle centered, yaw left, pitch forward. The exact stick command therefore depends on which mode your transmitter sticks are in.
When a parameter can be modified, the parameter’s current value will be shown on the right-hand side of the screen. In this case, roll left/right will adjust the parameter up and down. The screen to the right shows the current vTX settings. From here, you can change the frequency band, channel, and power level of the video transmitter. After making the changes, move the cursor to “Set” and press roll-right to confirm the settings.
