The 7Semi BMA400 3-Axis Digital Accelerometer Breakout Board STEMMA QT / Qwiic features the highly precise BMA400 3-axis accelerometer, delivering accurate 3D acceleration measurements with 12-bit digital resolution and 0.001g sensitivity.
Supporting selectable measurement ranges of ±2g, ±4g, ±8g, and ±16g, this ultra-low power sensor can detect tilt, orientation, tap/double-tap, and perform step counting with activity recognition—making it perfect for wearable devices and battery-sensitive applications.
Its Qwiic/STEMMA QT connector allows effortless plug-and-play integration, while dual power support (3.3V/5V) and flexible I2C/SPI interfaces ensure compatibility with a wide range of microcontrollers.
With two configurable interrupt pins and a compact design, this breakout board is ideal for robotics, motion sensing, vibration monitoring, and other STEM projects requiring precise and reliable acceleration data.
