Acceleration sensor: BMA580
The next-generation accelerometer with unique voice activity detection through bone conduction and advanced power mode features is the new smallest Bosch sensor in history (1.2 x 0.8 x 0.55 mm³.). It is especially designed for compact devices such as hearables requiring the smallest components.
- Smallest size
- Unique speech processing
- Highly flexible
