This is a breakout board for the ST's single-axis LY530ALH gyro.  The LY530ALH measures angular velocity along the axis with a full scale of ±300°/s. Two different analog outputs are provided for the z-axis - one 1x amplified and the other 4x amplified. A regulated voltage between 2.7 and 3.6VDC should be supplied to the power pins. We have the filtering circuits all set up, so you'll just need to connect the outputs to an ADC, and you're ready to go. This breakout board includes the gyro and all necessary filtering capacitors as shown. The 1x and 4x amplified outputs of both axes are connected to the 0.1" pitch headers, along with the power-down, self-test, high-pass filter reset, and power pins. We put the LY530ALH on our LPY5xxx gyro breakout boards. Don't be tricked by the pin-out, the x-axis outputs will not work.
