Have you ever wondered how fast the ballerina is whirling through her fouettés? Of course you have. To answer this question, one could attach a magnet to her leg and use a reed switch to measure the speed. What about the aerial gymnasts, though? It would be tricky because they can spin in three dimensions. Now you can finally find out which gymnast rotates faster with the help of our three-axis gyroscope. This gyro from the Troyka module series measures angular velocity around its own X, Y and Z axes. This is useful if you need to build control electronics that stabilize your aircraft by pitch, roll and yaw.

We designed this module based on the L3G4200D chip from STMicroelectronics.

The chip has a built-in temperature sensor, which will help achieve accurate sensor readings even under extreme conditions. Communication of the module with control electronics, such as an Arduino(cat://arduino), occurs via the I²C interface. This means that you only need two contacts to connect the module to the board.

We put a voltage regulator and a special I²C buffer on the module. Therefore, you can safely use it with voltages from 3.3 V to 5 V.


The connection of this modules differs from the standard - it has two three-pin connectors. One connector is used for power, while the other is for connecting to the I²C bus. Two 3-pin jumper cables needed for the connections are included in the kit.

There are several different ways to wire this module:

Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.

Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.

Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC. Two 3-wire loop cables are included.
