• portable motion tracking without GPS
  • CortexM4 microcontroller @80MHz from STM32
  • tracked data is saved to a micro SD card
  • realtime data transfer over Bluetooth Low Energy
  • 25h battery runtime


  • specifically designed to work without GPS
  • with energy efficiency in mind
  • provide tracked data for later analysis

layout design

  • the layout design is responsible for the small form-factor and 2-layer PCB
  • round design
  • smart parts placement


  • only the essential components are integrated
  • 9-axis motion sensor
  • very low energy bluetooth module
  • micro SD card slot for saving tracked data
