Besides raw acceleration, the chip counts steps, detects taps, orientation and activity changes, and buffers samples in a 1 KB FIFO, so your microcontroller can sleep until an interrupt wakes it.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eYou pick a range of \u003cstrong\u003e±2 g, ±4 g, ±8 g or ±16 g\u003c\/strong\u003e and an output data rate from \u003cstrong\u003e12.5 Hz to 800 Hz\u003c\/strong\u003e in normal mode. The BMA400 draws \u003cstrong\u003e14.5 µA\u003c\/strong\u003e in normal mode at its highest performance setting, \u003cstrong\u003e850 nA\u003c\/strong\u003e in low-power mode at 25 Hz and \u003cstrong\u003e160 nA\u003c\/strong\u003e in sleep mode (datasheet values at 1.8 V and 25 °C).\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThe board talks I2C at address \u003cstrong\u003e0x14\u003c\/strong\u003e, or \u003cstrong\u003e0x15\u003c\/strong\u003e when you change the ADDRESS jumper or pull the ADDRESS pin high. Two Qwiic connectors let you chain it with other boards, and two 4-pin 2.54 mm headers break out GND, 3V3, SDA, SCL, ADDRESS, INT1, INT2 and CSB. The 10 kΩ pull-ups on SDA and SCL can be disconnected with a jumper. Soldered provides an Arduino library and a MicroPython library with examples for readings, motion detection and step counting.\u003c\/p\u003e","brand":"Soldered Electronics","offers":[{"title":"Default Title","offer_id":66339307127133,"sku":"333419","price":8.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/5029\/1549\/files\/333419_photo_143538_bce3ed41-6710-42c7-a47d-54cd452ef4fd.webp?v=1793355959","url":"https:\/\/soldered.com\/products\/soldered-ultra-low-power-accelerometer-bma400-breakout","provider":"Soldered Electronics","version":"1.0","type":"link"}
