Notes

Module Specs

I have this mpu-6050 module from an aliexpress seller. It is similar to this module from sparkfun.

It is based on the Invensense MPU-6050, but packaged in a module that operates on 3-5V. These are the specs according to the seller:

  • 3-Axes Accelerometer Gyroscope Module For Arduino MPU 6050
  • Use chip: MPU-6050
  • 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
  • The gyroscope range: + 250 500 1000 2000 ° /s
  • Acceleration range: ± 2 ± 4 ± 8 ± 16 g
  • Pin Pitch 2.54 mm
  • Size: approx. 20151.2 mm(max)

Pin Connections

Pin Function Arduino Pin Connection
Vcc 3-5V 5V
Gnd Ground GND
SCL I²C clock A5
SDA I²C data A4
XDA I²C data for external compass n/a
XCL I²C clock for external compass n/a
AD0 selects I²C address 0x68 (low) and 0x69 (high) n/a
INT Interrupt out optional

Basic Example

The AccelGyroTest.ino sketch is a basic demonstration of reading raw values from the MPU-6050 using the Arduino Wire library. It is based on a sample from the Arduino playground MPU-6050 page.

It sends the readings out the serial connection:
