Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: None. We don't carry a direct replacement for this part but take a look at our gyro category for more 2-axis gyros. This page is for reference only.

Description: This is a breakout board for the ST's dual-axis LPY5150AL gyro.  The LPY5150AL measures angular velocity along the pitch and yaw axes with a full scale of ±1500°/s. Two different analog outputs are provided for both the x- and z- 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.

Not sure which gyro is right for you? Our Accelerometer and Gyro Buying Guide might help!

Features:

  • 2.7 to 3.6VDC power supply
  • Dual axis, pitch and yaw sensing
  • 1x and 4x amplified outputs for each axis
  • Low power consumption
  • All necessary filtering components included
  • Access to power-down, self-test, and high-pass filter reset pins

Dimensions: 0.6x0.7"

  • hi
    I am using the LPY5150 on a PCB with SiLabs uController (f340). The problem i get is that the voltage output at 1x, 1y, 4x and 4y keeps dropping continuously i.e. first they read 1.23V then they start dropping to .59V. The vref remains constant at 1.23V. Can anyone help with this problem?
    My configuration of the IC is as follow:
    ST(11) -> GND
    HP(13) -> GND
    PD(12) -> GND
    VCC (14,15,16) -> 3.3V with 0.1uf and 10uf capacitors.
    Low pass filter is implemented as per above schematic.
    Vref(7) -> is open
    FIL TVDO(2) -> OPEN
    CONT(3) -> OPEN
    any help ?

  • i have connected LPY5150 Breakout board like this:
    Vcc———–>3.3 volts.
    GND———->Gnd.
    ST,PD,HP—–>gnd.
    1x———->Not connected.
    outputs 4x–>Connected to analog pins of PIC16F877A.
    vref——–>connected to analog pin of PIC.
    iam reading three values 4x- X,Z and Vref.

    • Isn’t that a 5V micro? This gyro emits an analogue voltage at a 3.3v logic level.

      • iam using a voltage regulator to convert the 5V to 3 volts.
        I got some values from gyro which i need to integrate to get angle.Does this gyro allows integration?In some forum i saw that there is a problem with HP filter.Is it true?

  • hello all..
    Iam using LPY5150AL 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:
    X_deg=((V_out-V_reference)*5000/1024)/(sensitivity)
    where v_ref=1.23 as suggested in datasheet.
    THANKS ALOT..!
