{"title":"Adafruit Triple-Axis Accelerometer - ±2/4/8g @ 14-bit - MMA8451","handle":"adafruit-triple-axis-accelerometer-2-4-8g-14-bit-mma8451","url":"/products/adafruit-triple-axis-accelerometer-2-4-8g-14-bit-mma8451","description":"The Adafruit MMA8451 is a high-precision triple-axis accelerometer with a built-in 14-bit ADC, offering selectable measurement ranges of ±2g, ±4g, and ±8g. Designed by Freescale (now NXP), this sensor detects motion, tilt, and basic orientation — it can even tell you whether your project is in landscape or portrait mode.\n\nThe breakout board includes a 3.3V low-dropout regulator and I2C level shifting, making it safe for use with both 3.3V and 5V microcontrollers. An address selection pin allows multiple accelerometers to share a single I2C bus.\n\nKey Features\n\n\n14-Bit ADC Resolution – The most precise member of the MMA845x family\n\nSelectable Range – ±2g, ±4g, or ±8g full-scale range\n\n3-Axis Acceleration – Measures acceleration on X, Y, and Z axes\n\nBuilt-in Orientation Detection – Landscape/portrait mode and forward/back tilt detection\n\nI2C Interface – Shareable I2C bus with address selection pin (requires repeated-start I2C support)\n\n3.3V and 5V Compatible – Onboard voltage regulator and level shifting\n\nCompact Breakout – Two 2.5mm mounting holes and 8-pin 0.1\" header included\n\n\nIdeal For\n\nMotion and tilt detection projects\nOrientation sensing (landscape/portrait)\nWearable and portable electronics\nVibration monitoring\nLearning about accelerometers and I2C\n\n\nPackage Contents\n\n1× Adafruit MMA8451 Triple-Axis Accelerometer Breakout (assembled and tested)\n1× 8-pin 0.1\" header strip\n\n\nResources\n\nAdafruit MMA8451 Accelerometer Learning Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13704,"title":"Default Title","sku":"AF-2019","price":15.92,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
