MicroPython module for control RM3100 Geomagnetic Sensor.

# I2C bus

Just connect (VCC, GND, SDA, SCL) from your RM3100 board to Arduino, ESP or any other board with MicroPython firmware.

Attention! In this project, the sensor is connected via the I2C bus. Therefore, it is necessary to connect the A0(SA0) and A1(SA1) pins of the board to the GND or VCC! Otherwise, EIO exceptions will be thrown!

To enable the I2C bus, you need to connect the first (1) pin of the board, it is etched in the form of a square, to the VCC!

# Pitch

Before buying a sensor, you need to take care of buying female and male pins with a pitch of 2.0 mm. Additionally, you will have to purchase an adapter board from a pitch of 2.0 to 2.54 mm to connect the sensor to the breadboard!

You will have to carefully solder the pins and sockets into the boards.

# Supply

Supply voltage RM3100 3.3 Volts only!

# Upload

Upload micropython firmware to the NANO(ESP, etc) board, and then files: geosensmod.py, main.py, rm3100mod.py and sensor_pack folder. 

Then open main.py in your IDE and run it.
