SparkFun Triple Axis Accelerometer Breakout - BMA400 (Qwiic) Hookup Guide
El Duderino Introduction
The SparkFun Triple Axis Accelerometer Breakout - BMA400 (Qwiic) (Standard and Micro) offer a 3-axis acceleration sensor perfect for ultra low-power applications on a easy to use Qwiic breakout boards. The Qwiic system allows for integration into your I2C system with no soldering required. The standard size Qwiic breakout also includes 0.1"-spaced PTH pins connected to the sensor's communication interface and interrupt pins for applications that require a traditional soldered connection.
The BMA400 from Bosch Sensortech© has a full scale acceleration range of ±2/±4/±8/±16g with exceptionally low current consumption of < 14.5µA while operating at its highest performance settings. The sensor also includes a complete feature set for on-chip interrupts including step counter, activity recognition, orientation detection and tap/double tap.
This guide will go into detail on the features of the BMA400 and hardware on these boards as well as how to integrate it into a Qwiic circuit using the SparkFun BMA400 Arduino Library.
Required Materials
To follow along with this guide you will need a microcontroller to communicate with the BMA400. Below are a few options that come Qwiic-enabled out of the box:
If your chosen microcontroller is not already Qwiic-enabled, you can add that functionality with one or more of the following items:
You will also need at least one Qwiic cable to connect your sensor to your microcontroller.
