Description
Product description: MMA8452 – 3-axis I2C digital accelerometer – HW-616
A sensor for measuring accelerations in three axes: X, Y, Z within ±2 g, ±4 g, or ±8 g. MMA8452 accelerometer uses I2C bus to communicate with the central unit. The module has the necessary passive components for proper operation. The leads are solder fields to which goldpin connectors should be soldered – 2,54 mm raster allowing to connect the sensor with wires wires or directly the contact plate.
