SKU: SEN0095
The SD740 Tri-Axis Gyroscope Board is a versatile breakout module integrating a tri-axial micro-machined gyroscope with an ASIC for signal conditioning. It offers configurable filters for gain and bandwidth, zero rate bias adjustment, and a scalable full scale range of ±1024°/s to ±64°/s. With digital signal stability and a refresh rate of less than 100 microseconds, it supports SPI, I2C, and analog interfaces for various applications.
