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.
The acceleration values are collected using the KXTJ3 sensor.
It operates for 5 years using a battery.
This program is not suitable for mass production and commercialization as an example program.
B2B customers should contact [email protected].
For B2B customers, we develop firmware optimized for customers' purposes, such as low power, stabilization, and communication with gateways, for free.
