HW-127 GY-273 Magnetic Compass Module

HW-127 GY-273 Magnetic Compass Module

The HW-127 module is a 3-axis digital compass based on the QMC5883L IC. This sensor, much like a compass needle, aligns itself with the strongest magnetic field. Its internal sensor function relies on magnetic field-sensitive resistors arranged in an orthogonal coordinate system (x, y, z). Its I2C serial bus allows for easy interfacing.

Specifications:

• Supply Voltage: 2.16 - 3.6 VDC,
• I2C Interface with SCL, SDA,
• Measurement Range: 1.3 to 8 Gauss,
• Measurement Resolution: 12 bits,
• Measurement Accuracy: 0.73 - 4.35 Gauss,
• Baud Rate: 400kHz,
• Sensitivity: 230-1370 LSB/Gs,
• Output Frequency: 75Hz,
• Interrupt Pin: DRDY,
• IC: QMC5883
• Dimensions: 18 mm x 13 mm.
