Bosch introduces an economical motion sensor known as BMI323. This motion sensor detects and determines angle & position which are applicable to notebooks & tablets, toys & gadgets, game controllers & smart remote controls.
The BMI323 also features an Accelerometer (A): 16-bit digital resolution,
Gyroscope (G): 16-bit, (A): 16-bit or 0.06 mg/LSB
(G): 16-bit or 0.004 dps/LSB resolution, and A): ± 50 mg
(G): ± 1 °/s Zero offset (typ. over lifetime).
