Hi. We are working on a rov. We have Raspberry pi 4b and pixhawk 1 2.4.8. We want to use Ardusub and we tried to use Ardusub’s image but it did’nt work because it says it is for raspberry 3 but as i said we are using raspberry 4b. Is there a way to use the image?

Hi @erkamtb, welcome to the forum 🙂

Our old Companion Software was only designed to work with Raspberry Pi 3B, and is no longer being maintained. If you need to use a Raspberry Pi 4B it is strongly recommended to use [BlueOS](https://docs.bluerobotics.com/ardusub-zola/software/onboard/) instead.
