Model C Disk Image
Building your own Model C ROV from scratch? Download the disk image (disk image = your submarine's custom operating system) on this page to obtain all the onboard software your Raspberry Pi needs to function as an ROV controller! Once the disk image is on downloaded to your computer, you'll want to flash it by to a micro SD card (16 GB or greater). RaspberryPi.org wrote a great tutorial on how to do this here, or you can just watch the 40 second video below.
When you're following their directions, make sure that under the "CHOOSE OS" menu, you go to "Use custom" and select the Model C Disk Image you downloaded from this page.
