The Adafruit ADXL375 is a high-G triple-axis accelerometer capable of measuring up to ±200g of force. It communicates via I2C or SPI and includes STEMMA QT connectors for solderless I2C connections. An on-board 3.3V regulator and logic-level shifting make it compatible with both 3.3V and 5V microcontrollers.

The ADXL375 shares the same form factor and interface as the ADXL345 and ADXL343, but with a fixed ±200g range instead of selectable lower ranges. Existing library code for the ADXL345/ADXL343 will work with only a scaling adjustment, making migration straightforward.

Key Features

• ±200g Range – Measures extreme acceleration across three axes (X, Y, Z)
• Dual Digital Interface – I2C and SPI supported
• STEMMA QT / Qwiic Connectors – Solderless I2C connection via JST SH connectors
• On-Board Regulator – 3.3V regulator accepts up to 5V input
• Logic-Level Shifting – Works with 3.3V and 5V microcontrollers
• Motion Detection – Built-in shock detection with two configurable interrupt pins
• Mounting Holes – Four 2.5mm (0.1") holes for easy attachment
