harvestKIT Highlights

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.

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.

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.

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.

AMA3BHARV1 Energy Harvesting Reference Design

Ambiq's AMA3BHARV1 low-power optimized flexible platform for use with the evaluation and development of energy harvesting applications. harvestKIT ships bundled with microBUS Click modules from Nexperia, TDK, and Bosch.

harvestBOARD™ AMA3BHARV2 Energy Harvesting Reference Design

Ambiq's AMA3BHARV2 is the base board from AMA3BHARV1 that ships without Click board™ modules as shown. Build a custom kit by adding your own mikroBUS Click modules. This is also a great eval board for the latest QFN version of the Apollo3 Blue SOC (external debugger required) and/or as a reference design for power control of any MCU using an Artasie Real-Time Clock.
