●Description

The SparkFun Artemis Development Kit is the latest board to be released around the SparkFun Artemis Module and it allows access to more software development features than previous Artemis based boards. This Kit includes the SparkFun Artemis DK board as well as the accessories (Himax camera & USB-C cable) needed to get started right away. Recommended software used to program the Artemis DK are the Arduino IDE, Arm(R) Mbed(TM) OS (Studio and CLI), and AmbiqSDK. An updated USB interface (MKL26Z128VFM4 Arm(R) Cortex(R)-M0+ MCU, from NXP) allows the Artemis Dev Kit to act as:

• Mass Storage Device (MSD): Used to provide drag and drop programming to the Artemis Module.
• Human Interface Device (HID): Used for the debugging interface to the Artemis Module.
• Communication Port (COM): Used to provide a serial communication UART between the Artemis and the USB connection (PC).

The Artemis Module provides a Cortex(R)-M4F with BLE 5.0 running at 48MHz with an available 96MHz turbo mode and power as low as 6uA per MHz (less than 5mW). The SparkFun Artemis Module is fully FCC/IC/CE certified with 1M flash and 384k RAM you'll have plenty of room for your code. The flexibility of the Artemis module starts with our Arduino core. You can program and use the Artemis module just like you would an Uno or any other Arduino. Additional functionality stems from the ability of the Artemis Dev kit to run RTOS such as the Arm Mbed OS, or the AmbiqSDK.

Attached to the "Qwiic" I²C bus, we've added a LIS2DH12TR MEMS accelerometer (for things like gesture recogntion), a digital MEMS microphone, and an edge camera connector for the Himax CMOS imaging camera to experiment with always-on voice commands, and image recognition with TensorFlow and machine learning. All of the Artemis Development Kit pins are broken out to 0.1" spaced female headers (i.e. connectors). There are also two rows of breakout pins with 0.1" pitch spacing for headers; and a 0.08" pitch spacing to clip on IC-hooks, used by most logic analyzers. Additionally the Silk on the back of the Artemis DK acts as a chart to show pins by functionality (peripherals, ADC, PWM, UART0, & UART1) and act as an aid while developing software. The board is powered & programmed via USB-C, and includes a Qwiic connector to make I²C easy and is fully compatible with SparkFun's Arduino core to be programmed under the Arduino IDE.
