The 6-Axis Sub-G LongRang Solar Power Asset Tracker collects key information required for asset tracking such as acceleration, angular velocity, temperature, atmospheric pressure, and GPS location, and charges the battery using solar charging.
This is an example that provides quick testing of various service scenarios that require long-distance communication of 1Km or more.

It is a solar power asset 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.
Collect location information using L70+MAX2659 / GPS+LNA.
Charge the battery using the SPV1050 and solar panels built into the board.
Use LSM6DSL to collect acceleration and gyro sensor values.
MS560702 is used to collect information on temperature, air pressure, and altitude.
It operates for 5 years using a battery.
This program is not suitable for mass production and commercialization as an example program.
