The 7Semi BMA400 Sensor Module is a compact and low-power accelerometer used to measure motion, tilt, and vibration in 3 directions. It is designed for projects where battery life is important, like wearables and IoT devices. The module gives accurate digital output and supports both I2C and SPI communication. With Qwiic connector support, connection becomes very easy without complex wiring. It also supports features like step counting, tap detection, and activity sensing, making it very useful for smart applications.
Features:
• 3-Axis Sensor: Measures movement in X, Y, and Z directions
• Ultra Low Power: Best for battery and wearable devices
+• 12-Bit Resolution: Accurate and stable readings
• Selectable Range: Supports ±2g, ±4g, ±8g, ±16g
• I2C & SPI Interface: Flexible communication options
• Interrupt Pins: Can trigger actions based on motion
• Motion Features: Supports tilt, tap, double tap, and step detection
• Qwiic Connector: Easy plug-and-play connection
• Wide Power Support: Works with 3.3V and 5V
• Compact Design: Easy to integrate into small projects
• Ideal Use: Wearables, fitness tracking, IoT, robotics, motion sensing
