It supports normal and forced power modes for balancing measurement speed against power consumption. The board communicates over I2C only and is part of the [Qwiic ecosystem](https://soldered.com/collections/qwiic-ecosystem).\n\n### Quick start\n\n```python\nfrom bmm350 import BMM350, BMM350_OK\nimport time\n\nsensor = BMM350() # Or BMM350(address=BMM350_I2C_ADSEL_SET_HIGH) if ADSEL is pulled high\n\nwhile True:\n if sensor.get_sensor_data() == BMM350_OK:\n print(sensor.data.mag_x, sensor.data.mag_y, sensor.data.mag_z, sensor.data.temperature)\n time.sleep(1)\n```\n\nHave a look at the scripts in `Examples/` for basic readings, the sensor's physical interrupt pin, and the built-in self-test.\n\n### How to install\n\nUse [mim](https://checkmim.com/packages).\n\nor\n\nAfter [**installing the mpremote package**](https://docs.micropython.org/en/latest/reference/mpremote.html), install the library on your board using the following command:\n\n```sh\n mpremote mip install github:SolderedElectronics/Soldered-BMM350-MicroPython-Library\n```\nOr, if you're running a Windows OS:\n\n```sh\n python -m mpremote mip install github:SolderedElectronics/Soldered-BMM350-MicroPython-Library\n```\n\n### Repository Contents\n\n- **bmm350.py** - MicroPython driver class, I2C only\n- **package.json** - mip install manifest\n- **/Examples** - examples for basic readings, the physical interrupt pin, and the self-test\n\n### Examples\n\n| Example | What it does |\n| :------ | :----------- |\n| `bmm350-basicReadings.py` | Reads magnetometer and temperature data in a loop in normal power mode, the mode most applications want |\n| `bmm350-dataReadyInterrupt.py` | Uses the sensor's physical interrupt pin to know when a new reading is ready, instead of polling the interrupt status register |\n| `bmm350-selfTest.py` | Runs the sensor's built-in self-test and reports pass/fail per axis |\n\n### Hardware design\n\nYou can find hardware design for this board in _Soldered BMM350 Geomagnetic Sensor breakout_ hardware repository.\n\n### Documentation\n\nAccess library documentation [here](https://docs.soldered.com/).\n\n### About Soldered\n\n![Soldered Logo](https://raw.githubusercontent.com/SolderedElectronics/Soldered-Generic-Arduino-Library/dev/extras/Soldered-logo-color.png)\n\nAt Soldered, we design and manufacture a wide selection of electronic products to help you turn your ideas into acts and bring you one step closer to your final project. Our products are intented for makers and crafted in-house by our experienced team in Osijek, Croatia.
