Overview

CubeComputer is a general purpose on-board computer for nanosatellites. The OBC is built around an ARM Cortex-M3 MCU which delivers high performance at very low power. CubeComputer is fully compatible with the CubeSat standard and can thus be integrated with a wide variety of other CubeSat components. The module is radiation tolerant and is protected against SEUs and SEL’s through sophisticated error detection and correction techniques.
