Summary

The ISIS On Board computer (iOBC) is a flight-proven, high-performance processing unit based around an ARM9 processor with a speed of 400 MHz, making it one of the most capable on-board computers for CubeSats, currently available on the market within the same price range. Its pluggable daughter board offers additional flexibility and customizability by providing a wide range of extra interfaces for payloads, sensors or actuators in a compact form factor.
