MetaWear RG is the sensor platform for fast and easy IMU measurements in fitness, health and gaming applications.

This sensor is ideal for streaming sensor data.

The board comes is a very small rectangular form factor and 6 axis of motion sensing (3-axis accelerometer + 3-axis gyroscope).

Additional sensors can be attached via the general purpose I/O pins. There is an LED and push button switch on the board.

The board is powered by a lithium battery that is USB rechargeable.

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

The on board memory acts as a buffer to optimally stream sensor data directly to your Device (Smartphone, Hub, Tablet or PC).

Sensor data is available:

  • as a CSV file on your Smartphone, Tablet, Computer or BLE Device (using the MetaBase App)
  • as a CSV file in the MetaCloud (using the MetaBase App)
  • as a CSV file on the MetaHub (using the MetaBase App)
  • as a JSON array in your own App code (using our Python/C++/C#/Java/Javascript/Swift APIs)
