Which card to use
I typically ship 32 gig microSD cards with Dexter these days.
Where to get the base image
http://www.rulecity.com/browsetmp/dexterpi-v5.img.7z You may need to right-click to download this on some browsers.
You will need to decompress with 7zip ( https://www.7-zip.org/ ) so that you have a file that ends in ".img" .
How to write the new image
I recommend https://www.balena.io/etcher/
How to use the SD card once you have written an image to it
- Make sure Dexter's USB drive is inserted into Dexter's Raspberry Pi.
- Insert newly imaged SD card into Dexter's Raspberry Pi.
- Power on. If all goes well, the SD card will setup itself using data from the USB drive and you will be up and running in a few minutes. Dexter's video output will show a progress bar.
