Best magnetometer in this class

I have tested several modules, and the AK09911C offers the best balance of power consumption and update rate. Essential for any autonomous vehicle build.

Good value, clear documentation

The datasheet provided by the seller was helpful. Integration took less than an hour. Only giving 4 stars because the breakout board pins are slightly tight.

Solid sensor, minor packaging issue

The sensor itself is top-notch and provides consistent readings. The anti-static bag was slightly torn upon arrival, but the component was unaffected.

Reliable three-axis performance

Used this for a handheld navigation device. The noise floor is impressively low, and the I2C communication is robust. Highly recommended for professional prototypes.

5 FAQ

Q: Can this be used underwater?

A: The sensor chip itself is not waterproof. You must house the entire module in a waterproof enclosure if you intend to use it in underwater applications.

Q: What is the default I2C address?

A: The default I2C address for the AK09911C is typically 0x0C. However, please refer to the specific schematic included in the package as some breakout boards may vary.

Q: What is the lead time for bulk orders?

A: For orders exceeding 50 units, please contact our sales team directly. Standard bulk processing time is usually 3-5 business days before shipping.

Q: Does this come with a library for ESP32?

A: We do not provide a proprietary library, but this sensor is supported by popular open-source libraries like Adafruit_Sensor and SparkFun_AK09911 which work perfectly with ESP32.

Q: Is this module compatible with Raspberry Pi?

A: Yes, the MCU-9911 supports I2C interface which is fully compatible with Raspberry Pi GPIO pins. You will need to enable I2C in the raspi-config settings.
