Is Pixhawk 2.4.8 fully supported by px4?

Hello,

This is not entirely clear to me from what I read on the internet.
Is the px4 firmware mainly build for the Pixhawk 4 (as the name says) or is the Pixhawk 2.4.8 fully supported too?

Thanks and regards

pixhawk 2.4.8 its fully supported by PX4.
there are two versions… px4fmuv2 and px4fmuv3.
If your board its equipped with the stm32f427vit6 rev3 your board will be flashes with px4fmuv3.
Pixhawk 4 released by holybro its px4fmuv5
