Product Details

Demonstration circuit 2321A is a low power wireless sensor node development platform equipped with an E-ink display for user feedback. The system is capable of monitoring and managing its available energy, logging information from sensors and sharing this data over a wireless network.

The board is designed to connect to the DC2344A or DC2509A energy harvesting demonstration boards which output a regulated power supply as well as status information from energy harvesting ICs and their backup batteries. Two coulomb counters on the DC2321A allow the processor to monitor the energy output of these batteries which will vary depending on the amount of energy which can be harvested from the system’s surroundings.

A DC2274A-A SmartMesh Manager must be used in order to evaluate the networking features of the DC2321A.

Product Details

Demonstration Circuit 2048A is a nanopower buckboost DC/DC with energy harvesting battery life extender featuring the LTC3330. The LTC3330 integrates a high voltage energy harvesting power supply plus a DC/DC converter powered by a primary cell battery to create a single output supply for alternative energy applications. The energy harvesting power supply, consisting of an integrated low-loss full-wave bridge with a high voltage buck converter, harvests energy from piezoelectric, solar or magnetic sources. The primary cell input powers a buck-boost converter capable of operating down to 1.8V at its input. Either DC/DC converter can deliver energy to a single output.
