High precision gyroscope module JY-61 Series

1 Product Description

JY-61 series module integrates high-precision gyroscopes,
1)
accelerometers,, high-performance microprocessors and advanced
dynamics solver and dynamic Kalman filter algorithm to quickly solve
the current real-time movement of the module attitude .
The use of advanced digital filtering technology, can effectively reduce
2)
the measurement noise and improve measurement accuracy.
Integrates gesture solver, with dynamic Kalman filter algorithm, can get
3)
the accurate attitude in dynamic environment, attitude measurement
precision is up to 0.01 degrees with high stability, performance is even
better than some professional inclinometers!
Integrate voltage stabilization circuit, working voltage is 3v ~ 6v, pin
4)
level compatible 3.3V and 5V embedded system .
Supports serial port. Data output frequency 100Hz (baud rate 115200) /
5)
20Hz (9600 baud).
Module retains MPU6050 I2C interface, in order to meet the needs of advanced users
6)
to get the original data of MPU6050
Stamp hole gold plating PCB design, can be embedded in the user's PCB
7)
board.
8) 2layer PCB technology, thinner, smaller, and more reliable.
Note: This module does not contain magnetometer, no filtering for the
yaw angle, so yaw angle is calculated by integration, it will drift, the
yaw angle is accurate only in a short time. The X, Y axis angle is
accurate because it can be filtered by gravity field, it will not drift.
