5 kHz bandwidth in a 2.5×3 mm LGA
The IIS3DWBTR is a 3-axis digital accelerometer from STMicroelectronics that samples vibration and motion up to 5 kHz — an order of magnitude wider than typical industrial IMUs that top out around 400 Hz. The 14-VFLGA module (2.5×3 mm body, 14-LGA land pattern) keeps the board footprint small enough for handheld tools and embedded condition-monitoring nodes. Output is available over I²C or SPI, so the same BOM position works with a microcontroller that has either bus.
Selectable g-range and on-chip temperature sensor
Four full-scale ranges are selectable: ±2g, ±4g, ±8g, and ±16g. At ±2g the sensitivity is 16393 LSB/g; at ±16g it drops to 2049 LSB/g. For a vibration-analysis application measuring 0.5g peaks at 1 kHz, the ±2g range gives the best resolution — the noise floor on the wide-bandwidth path is low enough that the LSB count matters. That 105°C ceiling covers most industrial enclosures and automotive cabin-mounted modules — the part does not carry an AEC-Q grade, so it is not formally qualified for under-hood or powertrain duty.
