Product description: MSA311 - three axis accelerometer - Adafruit 5309
Three axis accelerometer with 14-bit resolution from Adafruit. Allows measurement of acceleration in three axes in the range: ± 2g/4g/8g/16g. For communication it uses SPI interface or I2C bus with fixed address 0x62. The chip has a low current consumption mode (only 2 µA). The product has compact dimensions: 25.2 x 17.7 x 4.6 mm and a low weight of 1.7g. It can be used in a variety of projects.
The MSA311 chip is similar to the MSA301. However, it is not its direct drop-in replacement. The chips have different I2C addresses: 0x62 and 0x26.
MSA311 - three axis accelerometer - Adafruit 5309.
Compatible with Stemma QT connector
The MSA311 three-axis accelerometer from Adafruit is equipped with two Stemma QT connectors, placed on the edge of the board. This standard is compatible with SparkFun Qwiic I2C. This allows you to connect the MSA311 to development boards and a wide range of other sensors using a suitable cable, without soldering.
