The Fermion ADXL345 breakout module provides precise measurement of static acceleration (tilt) and dynamic acceleration (shock, vibration) across three axes. Utilizing a MEMS capacitive sensing element and a 13-bit ADC, it delivers high-resolution data for applications requiring fine motion analysis. The sensor’s intelligent power management and built-in activity detection algorithms enable efficient, event-driven system design.
Designed for embedded systems, the module includes onboard level shifting and signal conditioning, making it compatible with both 3.3V and 5V logic levels. Its compact breakout format provides easy access to all pins for prototyping and integration into robotics platforms, inertial measurement units (IMUs), and IoT devices where accurate motion tracking is critical.
