Kallisto® is (currently) a PCB (printed circuit board) – based IoT sensor platform, which is available in three variants (sensor assemblies) (see product sheet). This ARM Cortex-M4 based platform is currently available for customers and is being further developed to include a “Stamp” module. The Stamp Module is a single-sided board, which can be easily integrated into other systems.
Ganymed® is the much more powerful platform based on a self-developed RISC-V core in a 3D SiP. 3D means that there is another wiring and assembly level on the SiP (see picture in the product sheet).
