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:

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
