FlYing four ais tYpe, self balanced vehicle optimal sensor scheme, some children's shoes said, no magnetic field sensor, there is no pressure sensor, can do four ais aircraft? Isn't the Yaw ais drift over time? I want to tell You is, the magnetic field and the pressure is chicken ribs for details, see the description at the end of the correlation analYsis.

Latest update software, support 51/AVR/Arduino/STM8/STM32, such as a varietY of single-chip.

The module comes with a voltage stabiliZing circuit, which can be compatible with the 3.3V/5V embedded system.

Module retains the I2C MPU6050 interface to meet the needs of high-level users want to access the underlying measurement data.

The use of advanced digital filtering technology, can effectively reduce the measurement noise, improve the measurement accuracy.

Internal module is integrated with the attitude solver, with the dynamic Kalman filtering algorithm, can under the dynamic environment accurate output module of current attitude, attitude measurement accuracy is 0.01 degree, high stability performance even better than some of the professional inclinometer.

Using the stamp hole gold plating process, quality assurance, can be embedded in the user's PCB board.

The volume is less than a 1 coin size, the thickness of the module 2mm, stamp hole design can be embedded into the user's circuit board.

PC to module

eplain

1. module power after the need to remain at rest, the internal module of MCU will in static module for automatic calibration (to eliminate gyroscope zero drift), after calibration Z ais angle will re initialized to 0, Z ais angle output is 0, visual for the completion of the automatic calibration of signal.

2.The factory default settings using the serial port, baud rate115200Frame rate.100Hz. Configuration can be configured through the PC software, because all of the configuration is power down save, so just configure once on the line.
