This sensor can sense ranges from +-4 gauss (+- 400 uTesla) up to +-16 gauss (+- 1600 uT or 1.6 mT). For ultra-high precision, 155 Hz update rate is recommended – but if you don’t mind a little loss of precision, the sensor can output at 1000 Hz.
To make life easier so you can focus on your important work, we’ve taken the LIS3MDL 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!).
