Product Description
High Precision MEMS Gyroscope Chip with 1°/h Bias Instability for IMU Accelerometer Gyro
The MEMS Gyroscope Chip is a miniature solid-state angular rate sensor designed for accurate measurement of rotational velocity. It incorporates advanced MEMS micromachining technology and closed-loop drive architecture to deliver high precision, low bias instability, and excellent vibration resistance.
The chip features digital output through SPI or UART interface and is fully temperature compensated, ensuring consistent performance in dynamic environments. Ideal for applications in UAVs, robotics, vehicle stabilization systems, and tactical-grade inertial navigation units.

PCB Design
The decoupling capacitors for pins VCP, VREF, VBUF, and VREG should be placed as close to the pins as possible, with minimized equivalent resistance of the traces. The other ends of the decoupling capacitors for VREF, VBUF, and VREG are connected to the nearest AVSS_LN and then to signal ground via a magnetic bead.
The decoupling capacitors for VCC and VIO must be placed close to the corresponding pins. When VCC is in normal operation, the overall current will be about 35 mA, requiring wide PCB traces to ensure voltage stability.
For smooth assembly, avoid routing under the package and locate components away from stress concentration areas. Avoid placement near large heat dissipation elements, external mechanical contact points, and areas prone to warping during installation.
