The GY-271 HMC5883L Magnetometer Module is a high-performance 3-axis digital compass sensor designed for precise magnetic field detection and heading orientation in embedded electronics and robotic systems. Built around the HMC5883L chip by Honeywell, this compact module can measure the magnetic field strength in the X, Y, and Z axes, making it ideal for digital compasses, GPS navigation enhancement, autonomous vehicles, and robotic direction control.

Operating over an input voltage range of 3V to 5V, the module is fully compatible with most microcontrollers, including Arduino, Raspberry Pi, ESP32, STM32, and others. It communicates via the I2C interface, making integration simple and efficient with open-source libraries readily available.

The GY-271 offers high sensitivity and stable performance, with an internal 12-bit ADC that converts magnetic field data into accurate digital output. Its small size and low power consumption also make it suitable for portable and battery-operated devices.

  • We will assess your diagram and provide a quotation based on the complexity and requirements.

Special Offer for New Customers!!

New customers receive a special introductory discount on their first PCB layout/design project.
This allows us to review your design requirements and build a long-term working relationship.

How to Request a PCB Layout / Design

  1. Send your complete schematic or diagram via our Facebook page.
  2. Our team will review your diagram carefully to understand the design scope and requirements.
  3. detailed quotation will be provided based on:
    • Design complexity
    • Board size and number of layers
    • Components and package types
    • Special routing or manufacturing requirements

📌 Providing your diagram is essential so we can give you an accurate and fair quotation.

PCB Layout & Design Requirements

To ensure quality and accuracy, please note the following:

  • All schematics must be clear, complete, and properly labeled
  • Specify:
    • Board dimensions (if available)
    • Number of PCB layers
    • Preferred components or footprints (if any)
  • Hand-drawn, unclear, or incomplete schematics are not accepted
  • Rush or urgent requests may incur additional charges
