The InvenSense MPU-6050 sensor contains a MEMS accelerometer and a MEMS gyro in a single chip. It is very accurate, as it contains 16-bits analog to digital conversion hardware for each channel. Therefor it captures the x, y, and z channel at the same time. The sensor uses the I2C-bus to interface with the Arduino.
The MPU-6050 combines both an accelerometer and a gyro.
2 kind of headers included
The power supply: 3-5 v (internal low voltage difference voltage stabilizing)
Communication: standard IIC communication agreement
Chip built-in 16 bit AD converter, 16 bits of data output
