L3GD20H 3-Axis Gyroscope

Overview of the L3GD20H 3-Axis Gyroscope breakout board

A triple-axis gyroscope is a device for measuring angular rotational velocity using 3 different axes: pitch, roll and yaw.

It is therefore an essential tool if you want to measure the exact position and movement of a mobile robot or any other mobile device.

This L3GD20H 3-Axis Gyroscope breakout board is a new and improved version of the L3GD20 and L3GD4200.

It is smaller and consumes less power, but is still compatible with the programming codes used for the L3GD20. The L3GD20H 3-Axis Gyroscope breakout board offers numerous possibilities in terms of settings (3 sensitivity levels, high-pass and low-pass sensor filters).

The chip is equipped with an I2C/SPI interface, allowing you to communicate with all types of microcontrollers.

Note that the chip was initially only 3.3 V compatible, it was therefore integrated into a breakout board equipped with level shifting circuitry so your L3GD20H gyroscope is also compatible with 5 V.

You can therefore use it with your Arduino board by connecting your PCB’s SDA pin to your Arduino’s I2C pin.

Finally, this breakout board is easily integrated into projects thanks to its four 2.1 mm diameter mounting holes, compatible with #2-56 Imperial and M2 screws.
