TheColonelYoung/RingOne
3D air mouse based on STM32 - Can be used for controlling CADs and every other manipulation in 3D space. Is based around STM32L452, IMU LSM6DSL (gyroscope and accelerometer) and Bluetooth low power module RN4871.

The INA199EVM is a module made by Texas Instruments with 6 pins. Power Management - Modules ROHS.
PCBKit's library has its KiCad symbol (4ms-ic:INA199, from 4ms) and its footprint (4ms_Package_SOT:SOT-363_SC-70-6, from 4ms), ready for a KiCad board. JLCPCB lists it (part C17349267). 3 open-source boards in 3 repositories on GitHub use it.
