STM 400J features an energy harvesting interface for the implementation of self-powered products. The minimal standby power consumption makes it especially suitable for energy harvesting wireless solutions such as bidirectional temperature sensors, sensors in building services and innovative actuators. STM 400J can be powered by a solar cell, available in two sizes – ECS 300 and ECS 310. The module is programmable with custom firmware created with Dolphin V4 API. Standard product source code is available for your use.
