Compact and reliable
I love how small this module is. It fit perfectly into my custom rover chassis. The documentation included was clear enough to get me started within minutes. Highly recommended for beginners.

Good value, requires calibration
Works well once calibrated. Out of the box, the readings were a bit off, but after following the documentation for calibration, it locks onto North accurately. Great price point for hobbyists.

Exceeded expectations
For the price, you really can't beat this. It provides consistent heading data even when tilted slightly. The build quality feels sturdy, and the soldering points are well-defined.

Solid performer for education
We bought ten of these for our high school robotics club. They are durable and easy for students to understand. One unit had a slightly loose pin header, but otherwise, they are great.

Easy serial integration
The serial output format is straightforward. Parsing the string to get the angle in my Python script was trivial. No interference issues so far even near my motor drivers.

Perfect for my Arduino robot project
This compass module was exactly what I needed. The UART output makes it incredibly easy to interface with my Arduino without dealing with complex I2C registers. The heading data is stable and updates quickly.
Q: Does this module work directly with Raspberry Pi?
A: Yes, it works with Raspberry Pi via the UART GPIO pins. Ensure you enable the serial console in the Raspberry Pi configuration settings and connect the TX/RX lines correctly.
Q: What is the update rate of the sensor?
A: The default update rate is approximately 5Hz to 10Hz depending on the firmware version. This is sufficient for most ground-based robotics and navigation applications.
Q: Is the module waterproof?
A: No, the GY-26 module is not waterproof. It should be housed in a protective enclosure if used in outdoor environments where it might be exposed to rain or moisture.
Q: Can I change the baud rate?
A: Yes, the baud rate can be configured by sending specific command strings to the module via serial. Please refer to the included documentation for the exact command syntax.
Q: Does it require an external crystal oscillator?
A: No, the module has an onboard crystal oscillator and all necessary components to function. You only need to provide power and connect the serial lines.
