F405V4 Flight Controller Original Factory Firmware Description

Original Factory Firmware Change Notice:

The original factory firmware of the F405v4 flight controller has changed. The original factory firmware version was betaflight 4.4.2, and after the change, the F405v4 original firmware version is now betaflight 4.4.3. 

The original factory firmware may cause issues when reading black box files (this is a problem specific to the original factory firmware, but the online version of betaflight 4.4.2 is normal).

Therefore, if you find that the original factory firmware is betaflight 4.4.2, please reflash the firmware of the flight controller.

Original Factory Firmware Functionality Description:

Due to the "cloud build" feature introduced in version 4.4 and above, the firmware can only include a limited set of functions.

The original factory firmware for the F405v4 flight controller (betaflight 4.4.3) already included most commonly used functions (you can refer to the image below for specific information).

If you have other specific functionality requirements that are not included or if you want to use a different firmware version, you can refer to the article below to flash the firmware onto the flight controller.
