The watchdog circuit is built using radiation hard components, but aside from maybe light shielding on the micro SDCards we'll be flying the modules as-is. The goal is to characterize them in that environment and determine failure rates to see if it's reasonable to then build a fault-tolerant system (using voting, as you suggest) later on.
