  • The SparkFun Qwiic BMA400 Micro Triple Axis Accelerometer Breakout offers a 3-axis acceleration sensor perfect for ultra-low-power applications.
  • Micro Triple Axis Accelerometer features: Qwiic Micro Sized Board (0.75in x 0.30in / 19.05mm x 7.62mm) Supply voltage range, 1.72 - 3.6V, Ultra-Low current consumption, < 14.5µA at highest performance settings, I2C interface (Qwiic-enabled) I2C addresses, 0x14 (Default), 0x15. Selectable acceleration ranges, ±2/±4/±8/±16g.
  • Also Features: On-chip interrupt features, Auto-low power/auto wakeup, Step counter, Activity recognition (walking, running, standing still) Motion detection, Orientation detection, Tap/double tap. Output data rate range, 12.5 - 800Hz (Normal Mode) 25Hz (Low-Power Mode) 1x Horizontal Qwiic Connection Port
  • Dubbed the first "real" ultra-low power acceleration sensor, the BMA400 is perfect when used in both wearable and smart home applications. Where this sensor shines, however, is its ability to distinguish between critical situations and false signals by avoiding false alarms.
  • The Qwiic system allows for integration into your I2C system with no soldering required. While the Micro size does not allow for a traditional 0.1"-spaced PTH header for communication, the board does route an interrupt and ground pin to a through-hole connection.
