MetaWear CPRO is a tiny, coin-cell powered, Bluetooth Low Energy Sensor Platform with an SDK so you can program it wirelessly using your Smartphone.

The CPRO board is based on the nRF51822 SOC from Nordic built around an ARM® Cortex™ M0 CPU and Bluetooth Low Energy.

Built on top of our successful MetaWear C, the CPRO is an ultra-miniature board with even more features, including 10 axis of motion sensing powered by a coin cell.

The CPRO board comes with the following sensors:

BMI160 Accelerometer
BMI160 Gyroscope
BMM150 Magnetometer
BMP280 Pressure
LTR-329ALS Ambient Light
BMP280 Temperature and redundancy thermistor
Additional sensors can be attached via the general purpose I/O pins. There is also an LED and push button switch on the board.

You can download the 3D MCAD model to make your own case or just to check out how small this thing is. The CPRO is just 24mm in diameter and 3 mm in height with the battery. The datasheet is also available here: MetaWearCPSv0.5

The CPRO has on board flash memory (for 15,000 sensor data entries) so you can log sensor data and download it to your phone later.

The battery lasts up to several months on a single CR2032 coin cell.
