The GY-45 module integrates the MMA8452Q, a smart, low-power capacitive MEMS accelerometer. It provides high-resolution 14-bit digital output via the I2C bus, eliminating the need for external signal conditioning. The sensor features embedded intelligence for motion detection, including free-fall, single/double-tap pulse, and vibration sensing, which can be configured to trigger its interrupt pins.
Designed for prototyping and embedded systems, the module includes onboard level shifting and pull-up resistors, making it directly compatible with 3.3V and 5V logic systems. Its compact form factor and standard 0.1″ pin spacing facilitate integration into breadboards and PCBs.
