What is the nPZero Stamp

Nanopower | nPZero power-saving IC

The nPZero G1S Stamp is a compact 15×15 mm module designed to simplify evaluation and integration of the nPZero power-saving IC. It enables developers to test the IC directly on a PCB or breadboard without requiring a complex prototype setup.

The nPZero Stamp module includes the minimum circuitry and components needed to run a system with the nPZero power-saving IC. It allows connection to a host MCU and up to four peripherals, making it suitable for most IoT systems.

Its small footprint and straightforward pin access make it ideal for rapid prototyping, validation, and firmware development involving power control.

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 prototypes and proof-of-concept where sleep mode power consumption is critical.

The nPZero Stamp can be connected via jumpers or soldered directly onto a custom PCB, lowering the efforts of a successful prototype to the absolute minimum.

The onboard nPZero IC 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.
