Modern drones are highly complex for various uses such as inspection, surveillance, surveying, or logistics. During flight and in control and communication, a large amount of data is generated, including image material, sensor information, or navigation data, which sometimes need to be stored and processed in real-time. Swissbit offers storage media, such as SD cards, that securely store your data and protect them from unauthorized access.
These cards can be used in all drone types and classes, from hobby drones to industrial drones.

Securing system integrity is a key application of our Security Level 2 microSD cards. We have implemented an open-source example compatible with various Raspberry Pi models, making it truly plug-and-play retrofit security. This example serves as a reference for a variety of embedded Linux systems. Built on uBoot, it offers the flexibility to be adapted for numerous platforms, and we provide the full source code to facilitate customization for your unique requirements.
