1.Overview
The SparkFun Artemis is a Cortex-M4F based BLE module using the Apollo3 micrcontroller from Ambiq. The
Artemis is capable of running machine learning algorithms with the low current consumption of 6 μA/MHz at
3.3V. The Artemis has an integrated 2.4GHz antenna and incorporates all the necessary circuitry to implement
a low power BLE enabled microcontroller.
