Product Details

Voyager 4 uses triaxial digital out MEMS sensors including the ADXL382 and ADXL367. The design also includes the MAX32666 BLE and MAX78000 AI microcontrollers. Flexible and PCB area efficient PMIC power devices have been added as load switches for enhanced wireless sensor power savings. A BLE 5.3 Adapter with Antenna is included in every Voyager4 kit. Voyager4 uses BLE which makes it compatible with any PC with a Bluetooth Radio, but to ensure optimal performance and range, using the adapter when communicating with Voyager4 is recommended.

The solution operates in two modes:

Data Collection/Streaming mode – In this mode, the data is sent to the Host PC for AI model development.

Normal Operation/AI mode – In this mode, the anomaly alert is sent to the Host PC and user can decide to gather more ADXL382 data.
