The MSA311 is a super small and low-costtriple-axis accelerometer. It’s inexpensive, but has just about every ‘extra’ you’d want in an accelerometer. The I2C address is 0x62This sensor communicates over I2CorSPI (our library code supports MSA311 and MS301) so you can share it with a bunch of other sensors on the same I2C bus. There’s an address selection pin so you can have two accelerometers share an I2C bus.To get you going fast, we spun up a custom-made PCB in theSTEMMA QTform factor, making them easy to interface with. TheSTEMMA QT connectorson either side are compatible with theSparkFun QwiicI2C connectors. This allows you to make solderless connections between your development board and the MSA311 or to chain with a wide range of other sensors and accessories using acompatible cable.QT Cable is not included, but we have a variety in the shopWeve of course broken out all the pins to standard headers and added a voltage regulator and level shifting so allow you to use it with either 3.3V or 5V systems such as the Raspberry Pi + Feather series or Arduino Uno respectively.Comes with a bit of 0.1″ standard header in case you want to use it with a breadboard or perfboard. Four mounting holes for easy attachment.Technical DetailsThree-axis sensing, 14-bit resolution2g/4g/8g/16g selectable scalingI2C interface on fixed I2C address 0x62Interrupt outputMultiple data rate options 1 Hz to 500 HzAs low as 2uA current draw in low power mode (just the chip itself, not including any supporting circuitry)Tap, Double-tap, orientation & freefall detectionProduct Dimensions: 25.2mm x 17.7mm x 4.6mm / 1.0″ x 0.7″ x 0.2″Product Weight: 1.7g / 0.1ozDocumentsMSA311 Datasheet
