Adafruit have announced the availability of its new Triple-axis Magnetometer offering a sensor capable of sensing ranges from +-50 gauss (+- 5000 uTesla!) with no range-setting required. For high resolution, you can read at 100 Hz update rate, and if you were not too concerned about a slight loss of precision the sensor can output at 150 Hz. Adafruit explains a little more about the Triple-axis Magnetometer, LIS2MDL, STEMMA QT / Qwiic board which is now available to purchase priced at $5.95.
“We based this breakout on ST’s LIS2MDL, a great general purpose magnetometer with a very wide range and bot I2C and SPI interfaces. This compact sensor uses I2C to communicate and it’s very easy to use. Simply download our library and connect the SCL pin to your I2C clock pin, and SDA pin to your I2C data pin and upload our test program to read out magnetic field data. If you’d like, you can also use SPI to receive data (we just happen to prefer I2C here)
To make life easier so you can focus on your important work, we’ve taken the LIS2MDL and put it onto a breakout PCB along with support circuitry to let you use this little wonder with 3.3V (Feather/Raspberry Pi) or 5V (Arduino/ Metro328) logic levels. Additionally, since it speaks I2C you can easily connect it up with two wires (plus power and ground!). We’ve even included SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder! Just wire up to your favorite micro and you can use our CircuitPython/Python or Arduino drivers to easily interface with the LIS2MDL and get magnetic measurements ASAP.”
