SCL3300-D01 is a high-performance 3-axis MEMS inclinometer of Murata.

# CL3300-D01

SCL3300-D01 is a high-performance 3-axis MEMS inclinometer from Murata. It adopts capacitive 3D-MEMS technology with an on-board angle calculation ASIC, outputting tilt angles directly, unlike a standard accelerometer. It integrates mechanical damping for excellent vibration resistance, featuring high stability for industrial use, and is packaged in a 12-pin molded SMD package.

> 

> Sales note for differentiation: It is different from IMUs such as the LSM6DSO. It is designed for static / quasi-static tilt measurement and not suitable for high-speed dynamic attitude applications. Its advantages include low long-term temperature drift, vibration immunity and direct angle output, so the MCU does not need to perform arctangent calculations.
