## 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. The 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. Key Features 14-Bit ADC Resolution – The most precise member of the MMA845x family Selectable Range – ±2g, ±4g, or ±8g full-scale range 3-Axis Acceleration – Measures acceleration on X, Y, and Z axes Built-in Orientation Detection – Landscape/portrait mode and forward/back tilt detection I2C Interface – Shareable I2C bus with address selection pin (requires repeated-start I2C support) 3.3V and 5V Compatible – Onboard voltage regulator and level shifting Compact Breakout – Two 2.5mm mounting holes and 8-pin 0.1" header included Ideal For Motion and tilt detection projects Orientation sensing (landscape/portrait) Wearable and portable electronics Vibration monitoring Learning about accelerometers and I2C Package Contents 1× Adafruit MMA8451 Triple-Axis Accelerometer Breakout (assembled and tested) 1× 8-pin 0.1" header strip Resources Adafruit MMA8451 Accelerometer Learning Guide
