LPY550AL Dual-Axis (Pitch and Yaw or XZ) Gyro with ±500°/s and ±2000°/s Ranges

This gyroscope board is a basic carrier/breakout board for the ST LPY550AL dual-axis gyro, which measures the angular rates of rotation about the pitch (x) and yaw (z) axes. Two separate analog voltage outputs for each axis provide angular velocity ranges of ±500°/s and ±2000°/s. This board has a 3.3V regulator for easy integration with 5V parts, includes a low-pass filter on each output for noise reduction, and is smaller than competing products.

Specifications:

Size: 0.5" x 1.0"
Weight: 1.2 g (1)
Minimum operating voltage: 2.7 V (2)
Maximum operating voltage: 16 V (3)
Axes: pitch (x) and yaw (z)
Measurement range: ±500°/s and ±2000°/s
Sensitivity: 2 mV/(°/s) and 0.5 mV/(°/s)

Notes:

(1) Without included hardware.
(2) Voltages below 3.6 V should be connected directly to the 3.3V pin.
(3) Internally regulated to 3.3 V.

This two-axis gyro is essentially a carrier board or breakout board for ST’s LPY550AL MEMS (micro-electro-mechanical systems) gyroscope; It is recommend that careful reading of the the corresponding datasheet is done before using this product.

Although these are great ICs, their small, leadless packages make them difficult for the typical student or hobbyist to use. They also operate at 2.7 V to 3.6 V, which can make interfacing difficult for microcontrollers operating at 5 V. These carrier boards address both issues while keeping the overall size at half a square inch.

Features

• Integrated 3.3V regulator means no extra parts are required for integration into 5V systems.
• Assorted sensitivities from ±100°/s to ±2000°/s available.
• Optional power-down input; may be shorted to a neighboring ground pin if the low-power state is not needed.
• Optional embedded self-test input; this is connected to a pull-down resistor on the board to disable it by default.
• Two-stage low-pass filtered output to reduce high-frequency noise.
• Two mounting holes (0.086", intended for #2 screws) for sturdy connection to a robot chassis or project enclosure.
• Small size: 0.5" × 1.0".

The gyro boards ship with a 1x10 0.1" breakaway male header strip.
