Mender supports secure and robust OTA updates of Debian-based Operating System images such as Raspberry Pi OS. The Debian family of OS are highly functional and provide a range of options for running embedded devices in an IoT project. Debian is often seen as a good starting point when setting up a proof of concept in an IoT project as it is relatively easy to set up and configure and there is a tremendous amount of community support available. A Raspberry Pi 3 or 4 based on Raspberry Pi OS is a common choice for an IoT proof of concept. Yocto is a more streamlined custom Linux distribution requiring less system resources but a higher level of knowledge and practice. Mender supports OTA updates for both Debian and Yocto.
