Important note: SCL3300-D01 is suitable for static and quasi-static tilt; It is not suitable for high-speed dynamic motion, there is no gyroscope, and dynamic violent shaking scenes will introduce a large angle error.

III. Core features of the product

Direct angle output: gravity → inclination calculation is completed inside the chip, and the main controller directly reads the angle, reducing the workload of firmware development.

Ultra-low noise, low drift: 0.001 ° / √Hz, suitable for long-term monitoring of small angles, such as the monitoring of small deformation of bridges and tower cranes.

IV. Comparison with the same family and competitors

Location

Core differences

SCL3300‑D01

Three-axis inclination, angle output

Main model, ±90°, SPI, direct angle output

SCL3400

Biaxial inclination

Only X/Y axis, lower cost, suitable for 2D leveling scenes

Competitor SCA330

Old generation Murata inclination

The noise and temperature drift of SCL3301-D01 are weaker, and it is gradually being replaced.

Common 6-axis IMU (such as BMI088)

IMU with gyroscope

The software needs to calculate the tilt angle itself, and the static drift is greater than SCL3301-D01.

Selection tip: only choose SCL3301-D01 for static tilt; Motion posture and dynamic tilt angle are required, and a gyroscope IMU (SCH16T series) should be selected.

V. Typical application scenarios

Structural Health Monitoring: Long-term monitoring of micro-deformation of bridges, dams, towers, and wind turbine foundations

Industrial platform: laser equipment, radar turntable, optical equipment leveling

Robot: static base level detection, AGV body tilt alarm

High precision level instrument, attitude reference base unit

VI. Supply Chain and Development Information

Status: Mass production and supply, long-term industrial life cycle

Evaluation board: SCL3300-D01-PCB official evaluation board, fast register debugging, performance verification Murata Man...

Interface: standard SPI, no need for special protocol, ordinary MCU can drive

Note: It can only measure the inclination caused by gravity. The motion acceleration will cause the angle distortion. It is not recommended to use this single in dynamic large motion scenes.
