Pebble Tracker from IoTeX

Designed to write sensor readings to a secure blockchain, Pebble Tracker from IoTeX is a secure, battery-operated, multi-sensor, cellular-IoT prototyping platform that uses a tamper-proof secure element to convert real-world phenomenon into verifiable, blockchain-ready data. This new prototyping platform is built around Nordic Semiconductor’s latest low-power nRF9160 System-in-Package (SiP) and is driven by open-source firmware. It is equipped with GPS support, a wide assortment of other sensors, NB-IoT/LTE-M connectivity, and advanced security features that make it ideal for sophisticated logistical applications.

The nRF9160 SiP is an Arm Cortex-M33 processor that runs at 64MHz, 1MB of flash, 256kB of RAM, and support for Arm's TrustZone via the CryptoCell-310 security subsystem. The device includes support for LTE-M and NB-IoT connectivity in 700-2.2GHz bands, and GPS receiver function time-multiplexed with the LTE modem.  Besides, there is an on-board buzzer that offers 85dB/min sound pressure measured at 10cm. Other sensors included are the Bosch BME680 humidity, temperature, pressure, and air quality sensor, ICM-42605 three-axis gyroscope and accelerometer, and an AMSTSL2572 ambient light sensor.
