The SI‑MG‑3Q‑FB1 is a compact, high‑performance and cost‑effective three‑axis MEMS gyroscope built on mature micro‑electro‑mechanical system technology. It is designed to measure angular velocity along three orthogonal sensitive axes of the carrier and outputs high‑quality digital signals proportional to real‑time rotational angular velocity.
Integrated with professional embedded algorithms and full‑set compensation software covering full‑temperature calibration, installation misalignment correction and nonlinear error compensation, the gyroscope maintains outstanding and consistent performance under both static and dynamic operating conditions. It delivers stable, high‑reliability angular measurement data even in harsh and complex working environments.
