This board was inspired by the Adafruit feather series of boards and it is compatible with many of their peripheral wings. A complete getting-started guide is available at (ARM’s ) site with the.

The board also includes the MAX14690 wearable PMIC to provide power conversion and battery management. The form factor is a 23 x 52 mm (0.9 in. by 2.0 in.) dual row header footprint that is compatible with breadboards and off-the shelf peripheral expansion boards.

On board is a variety of peripherals including a dual-mode Bluetooth module, micro SD card connector, 6-axis accelerometer/gyro, RGB indicator LED, and pushbutton. This provides a power-optimized flexible platform for quick proof-of-concepts and early software development to enhance time to market.

Maxim suggests applications in areas such as; fitness monitors, portable medical devices, sensor hubs, sports watches and wearable medical patches. A list of features across the on-board chip set is on the following page.
