{"title":"ADXL343 - Triple-Axis Accelerometer (+-2g/4g/8g/16g) w/ I2C/SPI","handle":"adxl343-triple-axis-accelerometer-2g-4g-8g-16g-w-i2c-spi","url":"/products/adxl343-triple-axis-accelerometer-2g-4g-8g-16g-w-i2c-spi","description":"A versatile triple-axis digital accelerometer breakout featuring the Analog Devices ADXL343. With selectable sensitivity of ±2g, ±4g, ±8g, or ±16g and up to 13-bit resolution, this sensor handles everything from precise tilt measurement to high-speed motion tracking over I2C or SPI.\n\nBuilt-in motion detection features make tap, double-tap, activity, inactivity, and free-fall detection trivial — with two configurable interrupt pins. The ADXL343 is a near drop-in replacement for the popular ADXL345, with code compatibility and improved pricing. Onboard 3.3V regulator and level shifting work with any 3V or 5V microcontroller.\n\nKey Features\n\n\nSelectable Range – ±2g, ±4g, ±8g, or ±16g sensitivity\n\nUp to 13-Bit Resolution – High-precision digital readings\n\nI2C & SPI Interface – Flexible digital communication options\n\nBuilt-in Motion Detection – Tap, double-tap, activity, inactivity, and free-fall\n\n2 Interrupt Pins – Independently configurable for any motion event\n\n3V & 5V Compatible – Onboard regulator and level shifting\n\nADXL345 Code Compatible – Existing ADXL345 code works with minimal changes\n\nArduino & CircuitPython Support – Libraries for microcontrollers and Raspberry Pi\n\n\nIdeal For\n\nTilt and orientation sensing\nTap and gesture detection\nFree-fall and impact detection\nMotion-triggered projects and robotics\n\n\nPackage Contents\n\n1× ADXL343 Triple-Axis Accelerometer Breakout (assembled and tested)\n1× 9-pin header strip\n\n\nResources\n\nArduino Guide (Adafruit Learn)\nCircuitPython & Raspberry Pi Guide (Adafruit Learn)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":7022,"title":"Default Title","sku":"AF-4097","price":11.6,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":2,"option1":"Default Title"}]}
