The SparkFun Edge Development Board is designed to disconnect artificial intelligence capabilities -- such as voice or image recognition -- from the cloud. The idea of performing these computations in a decentralized location (or "edge") is how the board gets its name, but the Ambiq Apollo3 microcontroller is how the Edge gets its power. The Apollo3 is an ultra-low power microcontroller that features an Arm Cortex-M4 core running at 48 MHz but uses only 6 microamps per megahertz. Such a high computational to electrical power ratio can enable machine learning features even in battery powered IoT devices.
