GY-26 Digital Electronic Compass Sensor Module

The GY-26 is a low-cost digital compass module that uses a magnetoresistive sensor to measure the Earth's magnetic field and output a heading (azimuth) angle. An on-board microcontroller handles calibration and hard-iron compensation and returns the heading over UART or I2C, so it is easy to add to robots, navigation and orientation projects.

Key Features:

• Heading accuracy better than 5° when level, 0.5° resolution

• UART (TTL, 9600 baud) and I2C interfaces

• Normal, continuous and calibration modes

• Hard-iron calibration and adjustable declination angle

Specifications:

• Supply voltage: 2.6V – 5V (3.3V typical)

• Magnetic range: ±2 gauss

• Operating temperature: 0 – 70°C

• Size: approx. 26.5 × 26.5 × 11.5mm
