In this paper, we introduce a newly developed general-purpose IoT module and describe its functions and characteristics. The module is reprogrammable and equipped with adequate types of I/O ports, which contributes to its high versatility. In addition, it is expected to perform high endurability in strong radiation environment and therefore the module is ready for spacecraft application. Finally, the modules are applied to a broadcast-type autonomous distributed heater control system and the new modules are confirmed to be applicable to this system.
