Proton400k™ Version Comparison
Two versions of the Proton400k™ are available to better meet the demanding, specific needs of satellite missions. The Proton400k-L™ is a low power version of the PowerPC-based Proton400k™. Both versions are radiation hardened to withstand the harsh space environment.
Below is a short comparison of the Proton400k™ and Proton400k-L™ PowerPC-based processor boards for space. For full specifications, view the Proton400k™ datasheet and Proton400k-L™ datasheet. For a full specificication comparison, view the complete Proton400k™ short form.
