...where a bunch of geeks got together to make other people's ideas come to life.
The L3GD20 is a great IC, but it's small, leadless, LGA package makes it's difficult for the typical student or hobbyist to use. This little breakout board allows you to use this IC by breaking out all the pins to a breadboard. The pitch on the headers is 0.1". The board eliminates all the level shifting circuitry. The board will still work with your 5V microcontroller like the Arduino UNO because the I2C interface uses built in internal pull ups to 3.3V. (Power the gyro with 3.3 volts)
The newer L3GD20 uses a higher resonant frequency that makes it more resistant to audio noise and vibrations. It has many configurable options, including three selectable angular rate sensitivities, a choice of output data rates, an embedded FIFO for buffering output data, and a programmable external interrupt signal. The three angular velocity readings are available through a digital interface, which can be configured to operate in either I²C or SPI mode.
Arduino Library for the L3GD20 can be found here.
