This article presents the main functionalities of an autonomous device named S.A.N.D.R.O., powered by solar energy and featuring minimalist computational technology based on the Raspberry Pi. This device was originally conceived to enable the continuity of distance education in regions devoid of connectivity, such as many riverside localities in the Amazon. It became central in equipping schools with the purpose of remotely providing educational resources in crisis situations, as occurred in the year 2020 with the COVID-19 pandemic. These resources can be accessed through smartphones or kiosks, given that they fully replicate the modus operandi of the Internet, offering users a familiar experience despite the lack of actual internet connectivity. Beyond these adverse periods, one of the possible uses for the artifact is to enhance the ecotourism experience in the region, thereby contributing to transforming it into a Smart Tourist Destination. By adopting an innovative approach that reduces costs for consumers, the device can also be classified as a form of frugal innovation. This classification stems from its minimalist design and cost-effective technology, making advanced services accessible to communities and tourists in remote areas without requiring significant financial investment.
