    harvestKIT

    Endless Battery Life

    The harvestKIT™ is a versatile energy harvesting reference design platform that extends battery life by drawing energy from the environment or eliminates the need for batteries entirely by incorporating super capacitors and other energy storage elements.

    harvestKIT Highlights

    01

    SPOT Advantage

    At the core of harvestKIT is the Apollo3 Blue SoC, which utilizes Ambiq’s patented subthreshold power optimized technology (SPOT®) to deliver high energy efficiency and processing power for endpoint devices.

    02

    Intelligence Edge Device

    Significant compute cycles and on-chip memory capacity are available to run AI, ML, and Deep Learning algorithms that process the sensor data on-device.

    03

    BLE Connectivity

    The integrated Bluetooth® Low Energy (BLE) 5 radio relays data to host providing superior RF throughput and leaving plenty of resources available for user applications.

    04

    Versatility and Customization

    The kit supports a wide range of modules through its four mikroBUS™ sockets, allowing for easy expansion and customization.

    Applications

    Ambiq’s harvestKIT was targeted to improve the energy efficiency in smart home/buildings, remote monitoring, video game controllers, wearables, asset trackers, factory automation and more.
