A small sensor module that includes the MPU6050 sensor. It can read 3-axis acceleration, 3-axis gyroscopic as well as temperature data! And all of those via the super easy I2C protocol! And if you don't want to write your own driver then a quick search on the net will give multiple ones for free, written in various languages! On the PCB you will find a clear indication for the voltage range, the sensor name for quick searching, the read and write I2C addresses together with the pin out labeling. On top of those, a graphic representation of the sensor measuring values gives a better understanding of what you should expect as an output.

Using the onboard low dropout regulator (an LDO made by Microchip) the module can work under a wide operating voltage range - from 3V all the way up to 6V!
