WARNING: Regarding the Raspberry Pi shortage

The V-Core 3 requires a Raspberry Pi if you wish to use RatOS. However, due to the worldwide semiconductor shortage, availability of these can vary on a day-to-day basis. The store pages for the V-Core 3 kits now include a customizable option allowing purchase of a Raspberry Pi if required, and if they are currently in stock.

If the Raspberry Pi you wish to purchase is not currently in stock, the Raspberry Pi Locator website can be of great assistance in sourcing one in your country.
