Pebble Tracker
Pebble is a battery-powered, cellular-based, multi-sensor development board designed by IoTeX and Nordic Semiconductor, combining tamper-proof hardware and tamper-proof software to generate verifiable data. Built around Nordic Semiconductor’s latest low-power nRF9160 System-in-Package (SiP) and driven by open-source firmware, Pebble Tracker is equipped with GPS support, a variety of rich sensors, NB-IoT/LTE-M connectivity, and advanced security features that make it ideal for sophisticated logistical applications where trust is paramount. In combination with the IoTeX blockchain, its on-board capabilities allow developers to design and build innovative, decentralized IoT solutions that go well beyond conventional asset tracking.

Integrated Sensors
Pebble combines an environmental sensor (temperature, relative humidity, barometric pressure, altitude, and volatile organic compounds - VOCs), a motion sensor (3-axis gyroscope, 3-axis accelerometer), and an ambient light sensor. It's also equipped with cellular network connectivity and integrated GPS supporting precise, long range tracking of asset data using established cellular infrastructure.
