High precision gyroscope module JY-61 Series
User Manual
1 Product Description
1) JY-61 series module integrates high-precision gyroscopes,
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 .
2) The use of advanced digital filtering technology, can effectively reduce
the measurement noise and improve measurement accuracy.
3) Integrates gesture solver, with dynamic Kalman filter algorithm, can get
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!
4) Integrate voltage stabilization circuit, working voltage is 3v ~ 6v, pin
level compatible 3.3V and 5V embedded system .
5) Supports serial port. Data output frequency 100Hz (baud rate 115200) /
20Hz (9600 baud).
6) Module retains MPU6050 I2C interface, in order to meet the needs of advanced users
to get the original data of MPU6050
7) Stamp hole gold plating PCB design, can be embedded in the user's PCB
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.

3 Pin Description
As shown in the figure above, the coordinates of the module are indicated, and the right is the
X axis, the upper is Y axis, the Z axis is perpendicular to the surface of the paper to yourself. The
direction of rotation is defined by the right hand rule, that is, the thumb of the right hand is pointed
to the axial direction, and the four is the direction of the bending of the right hand.

(Notice：The switch of Six serial interface module needs to be configed as the following figure
when connecting to 6050 module)
4.2 Installation USB-TTL module driver
First, the module is connected via USB-TTL module to the computer, install the USB-TTL
module driver.
After installing the USB-TTL module driver, and then Device Manager can query
corresponding serial number, as below figure shows:
