Better understand activity tracking

OPen source Health activity kit

This open source project intends to allow users to discover activity tracking and how it works. By creating an open platform that counts your steps, and measures your heart rate, we hope to help demystify these technologies and allow users to tweak, change, modify, and create all possible data streams.

We are soliciting testers for our beta hardware !

  • BLE: Using the Simblee 32bit BLE/MCU module allows for awesome features, and is fully Arduino compatible. It enables long battery life, and easy use, including wireless programming
  • IMU: The Bosch BMI160 is the same IMU that is integrated into the Arduino 101 - 6-Axis IMU
  • PPG: Maxim 30101 offers high sensitivity, adjustable LED output power and multiple wavelengths. Designed specifically for wearables, and can capture PPG, and SpO2
  • Breakout: In addition to 3V3, GND, and the Simblee Reset pin, 5 unused pins on the Simblee are broken out including TX and RX.
  • Lights: RGB LED for full color blinky blinks
  • Battery Charging: USB input provides Lipo/Li-ion charging to a battery connected via JST
  • Wrist Strap: Includes velcro wrist strap
  • Protected: The entire PCB is conformally coated to provide protection from moisture and sweat

DESIGN FILES COMING SOON TO GITHUB (Includes code, PCB, and example hacks)
