Building your own wearable device is going to be much easier when you have MetaWear Coin to rely on. It is a coin-cell powered Bluetooth sensor with a SDK, allowing you to develop connected wearable devices. Whether you want to read temperature data, log motion info, or adjust how the MetaWear performs, you are covered.
MetaWear Coin has an ARM core, Bluetooth, a motion sensor, and a temperature sensor. Thanks to its iOS/Android SDKs, you will be able to develop custom solutions to interact with the board and its sensors. Like what you see? You can find out more on Kickstarter.
