SparkFun Artemis Module - BLE 5.0 module with Apollo3 microcontroller

Description

SparkFun Artemis is a BLE module based on the Cortex-M4F core, using the Ambiq Apollo3 microcontroller. Artemis is able to support machine learning algorithms at a low power consumption of 6 μA/MHz with a 3.3 V power supply. The module has an integrated 2.4 GHz antenna. Numerous peripheral circuits have been made available on the pins, including UART, I2C, SPI, I2S interfaces and ADC inputs.

Artemis has support in the Arduino IDE, which greatly facilitates the start of work with the module. Artemis also has an advanced HAL layer (hardware abstraction layer) that allows users to make the most of modern Cortex-M4F architecture.
