Looking to use a spare RPi3.

I run a radioD-Star hot-spot on a RPi3 and I therefore have capabilities to take an image file and burn it on mSD card. Is a similar image file available for WD? My spare RPi3 seems a good option to save me heating my study with a 180w PC running 24/7.

you can download consolewd for the raspberry pi onto that (using the default raspberry pi OS)

Thanks Brian

What size mSD card will suffice. I am starting from scratch.

4gb
you burn /install the raspberrian OS first onto the sd card and get that all runnning

then you put consolewd onto a usb stick and install it that way
