This article will discuss the selection of related products used within the ADI Voyager4 EV-CBM-VOYAGER4-1Z Wireless Vibration Assessment Kit

This kit is a complete low power vibration monitoring platform that allows designers to quickly deploy wireless solutions to devices or test fixtures. It detects abnormal motor behaviors through edge AI algorithms and triggers diagnostic and maintenance requests.

The complete Voyager4 system has accelerometers, AI, power management, transient protection, data integrity, and wireless connectivity ICs (Figure 3). In addition to the ADXL-832 MEMS accelerometer, the ultra-low-power, 14-bit, 100 Hz ADXL367BCCZ-RL7 triaxial MEMS accelerometer is used to wake up the BLE radio from deep sleep mode when a significant vibration or shock event occurs. This wake-up device consumes only 180 nanoamperes (nA), contributing to substantial power savings.

Using two accelerometers may seem redundant, but each has its role. The lower-performance, ultra-low-power ADXL367 provides ongoing monitoring and initiates a wake-up, while the more precise ADXL832 provides high-accuracy, high-speed data.

For signal-path management, the ADG1634BCPZ-REEL7 analog switch - a 4.5 ohm (Ω) four-circuit 2:1 single-pole double-throw (SPDT) CMOS device - is used to route the MEMS’ raw vibration data to either the MAX32666 BLE radio or the MAX78000 AI MCU, with the BLE MCU used to control the switch.

Several other peripherals are also connected to the MAX32666 BLE MCU, including the MAX17262REWL+T LiFePO4/Li-ion fuel gauge IC used to monitor battery current. The MAX32666 can stream the ADXL382 MEMS raw data to the host using either BLE or USB with the Future Technology Devices International (FTDI) FT234XD-R USB-to-basic serial UART interface IC.

On the electrical side, the MAX3207EAUT+T transient voltage suppression (TVS) diode array, with a negligible capacitance of just 2 picofarads (pf), provides ±15 kilovolt (kV) protection per the human-body (HBM) and air-gap models. For data integrity, the DS28C40ATB/VY+T Secure Authenticator delivers a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions.
