WHAT’S INCLUDED:

  • 1x MetaMotionRL board
  • 1x plastic white case (optional)
  • 1x USB rechargeable battery

Great motion and gesture tracking platform that comes with sensor fusion ideal for medical and health applications. This is our motion, health, fitness, and gaming sensor solution. 

ABOUT THE PCB:

MetaMotionR Lite is ideal for logging and streaming sensor data. Record raw sensor data via Bluetooth at up to 800Hz. Stream raw sensor data at up to 100Hz. Download the data and access it as a CSV file on your phone, hub, tablet, computer, server, or as a JSON file using our APIs.

The board comes in a very small rectangular form factor, 8MB of NOR FLASH memory, and sensor fusion with 9 axis of motion sensing (3-axis accelerometer + 3-axis gyroscope + 3-axis magnetometer).

The sensor fusion combines the measurements from 3-axis gyroscope, 3-axis geomagnetic sensor and a 3-axis accelerometer, to provide a robust absolute orientation vector in form of Quaternion or Euler angles. The algorithm fuses the sensor raw data in an intelligent way to improve each sensors output. This includes algorithms for offset calibration of each sensor, monitoring of the calibration status and Kalman filter fusion to provide distortion-free and refined orientation vectors.

There is an LED, GPIOs, and push button switch on the board. The board is powered by a 100mAH lithium-ion 3.7V battery. The board is based on the nRF52 SOC from Nordic built around a ARM® Cortex™ M4F CPU and Bluetooth Low Energy. The off board memory stores the sensor data on the MetaSensor to be retrieved at any time by 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 an array in your own App code (using our Python/C++/Java/Javascript/Swift APIs)
