XRotor Nano F4 Flight Controller w/ OSD

SKU: 31001001
$48.00 $31.99

Name: F4 Nano Flight Controller

  • Size: 27*27mm • Mounting Holes: 20*20mm
  • Firmware Version: OMNIBUSF4SD • BEC: 5V@1A • BB+, BB-: pins for connecting the “positive/+” & “negative/-” of the external buzzer.
  • LED-Strip: the FC outputs “control signals” to control the WS2812B LED strip. (Note: for the FCs with firmware from version 3.17, you need to key in “resource led_strip a8” first and then save on the CLI of the Betaflight software and then press the “Enter” button on the keyboard if you want to use the LED function.)
  • VBAT+: battery voltage output port. • Video-IN/OUT: video input/output port of the onboard OSD microchip


  • STM32 F405 MCU allows the FC to run the PID looptime and gyro with higher frequency.
  • SPI Sensor MPU6000 includes an accelerometer and a gyro.
  • Onboard OSD microchip which supports the DMA mode allows users to adjust its parameters via the Betaflight software. (Note: the OSD is controlled by the F4 MCU.)
  • The FC which supports Betaflight firmware & allows parameter adjustment via Betaflight software is more applicable to FPV race.
  • TF-card which can record and save more flight/black box data allows users to adjust the setup of their aircraft easily.
  • Compatible with various receivers like SBUS, SUMH, SUMD, SPEKTRUM1024/2048, XBUS, PPM and etc.
  • LED strip signal output port allows users to adjust the color & flash mode of the LED strip via the FC.
  • Volt/Amp monitoring port allows users to check the battery voltage ( VBAT+ port ) and current ( CRT port ) (extra current meter is needed).
  • Buzzer output port allows users to connect external buzzer(s) to the FC for warning or informing the flight status of the aircraft.
  • Micro USB port allows users to connect the FC to a PC to flash firmware and adjust parameters.

We strongly recommend reading through this user manual before use. Because we have no control over the use, installation, or maintenance of this product, no liability may be assumed for any damage or losses resulting from the use of the product. We do not assume responsibility for any losses caused by unauthorized modifications to our product. Besides, we have the right to modify our product design, appearance, features and usage requirements without notification. We, HOBBYWING, are only responsible for our product cost and nothing else as result of using our product. 

  • Read through this user manual before use.
  • Ensure all wires and connections are well insulated before connecting the unit to related devices, as short circuit will damage it.
  • Please ensure to solder all the wires & connectors well if necessary and not get soldering tin on any electronic components. We won’t be responsible for any damage resulting from soldering and installation.
  • Never use the joint pins beyond the ones included in the product box to fix or connect the FC (Flight Controller), ESC and image-transferring board, because the heights from pins to sockets between image-transferring board and FC, FC and ESC board are regulated/fixed. If the joint pins are too short, then they will cause the PCBs to deform; if they are too long, then they will affect the connection between pins and sockets and cause damage to relevant devices. We won’t be responsible for the damage or losses resulting from users’ carelessness.
  • Never fly the aircraft near crowd, we won’t assume any losses resulting from the crash of the aircraft.
  • Never use this unit near heat, moisture, strong acid or alkali and under other environmental conditions that bad for electronic components.
  • The unit is ready-to-use (it’s flashed with firmware before leaving the factory), we won’t be liable for any damage resulting from firmware flashing which is carried out by users.
  • The FC firmware is an open-source program, users can search relevant technical information on the internet and we won’t provide any technical support beyond the FC hardware.
