Description
The nPZero Stamp is a module including all necessary circuitry and components required to implement the nPZero IC in your design. This Stamp combines ultra-low power consumption with autonomous operation, making it perfect for devices where sleep mode power consumption is critical.
The Stamp can autonomously power up sensor peripherals, read data, and wake up the system as needed. It manages the system without an active MCU host by taking over the controller role, powering down the host, and autonomously handling power-up, configuration, and reading of peripheral data from up to 4 sensors. When required, it will power up the host and return control based on user-defined rules.
This allows the host to remain off for longer periods while the system continues to detect and respond to events, conserving energy. It significantly reduces power consumption compared to other options, both in active and sleep modes when managing peripherals.
