{"title":"Adafruit MSA311 Triple Axis Accelerometer - STEMMA QT / Qwiic","handle":"adafruit-msa311-triple-axis-accelerometer-stemma-qt-qwiic","url":"/products/adafruit-msa311-triple-axis-accelerometer-stemma-qt-qwiic","description":"The Adafruit MSA311 is a compact, low-cost triple-axis accelerometer with 14-bit resolution and a rich set of built-in motion detection features. Very similar to the MSA301 but with an updated I2C address (0x62 instead of 0x26), it includes tap/double-tap detection, orientation sensing, freefall detection, and configurable data rates from 1 Hz to 500 Hz.\n\nCommunicating over I2C, the MSA311 draws as little as 2 µA in low-power mode — ideal for battery-powered projects. The breakout includes a 3.3 V regulator and level shifting for compatibility with both 3.3 V and 5 V systems, plus STEMMA QT / Qwiic connectors for solderless wiring.\n\nKey Features\n\n\n3-Axis Accelerometer – 14-bit resolution with ±2g/±4g/±8g/±16g selectable range\n\nMotion Detection – Tap, double-tap, orientation, and freefall detection built in\n\nConfigurable Data Rate – 1 Hz to 500 Hz output options\n\nUltra-Low Power – As low as 2 µA in low-power mode (sensor only)\n\nInterrupt Output – Hardware interrupt pin for event-driven sensing\n\nI2C Interface – Fixed address 0x62, with address selection pin for two sensors on one bus\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection (cable not included)\n\n3.3 V and 5 V Compatible – On-board regulator and level shifting\n\nMounting Holes – Four holes for secure attachment\n\n\n\nNote: The MSA311 is very similar to the MSA301 but is not a drop-in replacement. The I2C address has changed from 0x26 to 0x62.\n\n\nIdeal For\n\nMotion and gesture detection\nTilt and orientation sensing\nWearable electronics and activity tracking\nBattery-powered projects requiring low-current accelerometry\n\n\nPackage Contents\n\n1× Adafruit MSA311 Triple Axis Accelerometer Breakout (assembled)\n1× Header strip\n\n\nResources\n\nSTEMMA QT Overview\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3049,"title":"Default Title","sku":"AF-5309","price":9.15,"on_sale":false,"in_stock":true,"available_quantity":89,"option1":"Default Title"}]}
