Gyro Breakout Board - LPR503AL Dual 30°/s

Replacement: None. There is no direct replacement for this board. This page is for reference only.

This is a breakout board for the ST's dual-axis LPR503AL gyro. The LPR503AL measures angular velocity along the pitch and roll axes with a full scale of ±30°/s. Two different analog outputs are provided for both the x- and y- axes - 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; 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.

    The schematic says the HPF is 0.5 Hz. My calculator says it is 0.03 Hz.
    Also, there are no pin numbers on the schematic so you will have to refer to the datasheet to know how the chip is wired. Hopefully, the pinouts are per the datasheet, but there is no way to know for sure without reverse engineering the PCB.

    hello all..
    Iam using LPY5150AL Breakout gyro. I have connected to a PIC16F877A microcontroller.The problem is that iam getting outputs of gyro around 1100 -1300 deg/sec when i rotate the axes.I donot know whether these values are correct are not??can anyone help me out..!
    The formula used is:
    where v_ref=1.23 as suggested in datasheet.

    is the ?30?/s for the 4X amplified outputs, or the 1X output?

  • Microzoul / about 15 years ago / 1

    I am not able to make this gyro works , I have unstable reading from all outputs (like noisy reading or something )
    this is the way I connected it
    VCC 3 volt
    Vref NC
    ST & PD & HP also NC
    I also tried to pull HP pin high , nothing changed

      me too, im getting noisy readings.. did u manage to fix the problem?
