I used to call my beagle Peanuts my FitBit. We walked together for hundreds of miles. With his passing last week, it is so nice that my nephew gifted me a FitBit One for Christmas.
The more I look at the little device and the data it is constantly communicating to my iPhone, the more admiration I get for all the technology jammed into this little package.
The components from an iFixit teardown include
STMicroelectronics STM32L 151 ARM-based SoC microcontroller
Nordic Semiconductor nRF8001Bluetooth chip
Accelerometer labeled 8304 AE D42 oW
Measurement specialties MS5607-02BA03 altimeter
- Polymer Li-Ion Battery
PCB mounted vibration motor
It also comes with a tiny USB Bluetooth dongle to synch with a laptop for initial set up.
Enough admiration of tiny components. Need to rack up some large metrics that Peanuts would approve.
