LPR550AL Dual-Axis Gyro with ±500°/s and ±2000°/s

SKU : LPR550ALDAG

Overview

These two-axis gyros are essentially carrier boards or breakout boards for ST’s LPR510AL, LPY510AL, LPR550AL, and LPY550AL MEMS (micro-electro-mechanical systems) gyroscopes; we therefore recommend careful reading of the the corresponding datasheets (listed under the “resources” tab) before using these products.

These parts are all members of ST’s latest family of dual-axis gyroscopes that differ only in their sensitivities and axes of rotation. Boards marked with a black X on the bottom silkscreen have ±100°/s and ±400°/s ranges; boards marked with a red X have ±500°/s and ±2000°/s ranges (each chip provides two sensitivities per axis—1x and 4x—and both are brought out to the user I/O on these carrier boards).

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".
