6-Axis Sub-G LongRang Motion Tracker

---

6-Axis Sub-G LongRang Motion Tracker collects essential information required for Motion Tracker using acceleration, gyro, and temperature sensors and transmits it using Sub-G communication.

This is an example that provides quick testing of various service scenarios that require long-distance communication of 1Km or more.

Key feature and functions

MCU	Description
CC1310	Sub-G SoC

Sensors	Description
LSM6DSL	6 Axis Accelerometer, Gyroscope Sensor
Si7201	Hall Sensor
Si7501	Temperature Sensor
Battery	1/2 AA Battery 1200mAh

It is a motion tracker capable of Sub-G communication.

Sub-G wireless communication is performed using CC1310 SoC

It can be turned on and off using Si7201 hall sensor and magnet.

Use LSM6DSL to collect acceleration and gyro sensor values.

The temperature value is collected using the Si7051 sensor.

It operates for 5 years using a battery.
