Adafruit Wide-Range Triple-axis Magnetometer - MLX90393 STEMMA QT SF_AVR 4GHz ultra low-power wireless communication

4GHz ultra low-power wireless communication – it even features on-chip NFC tag support

Even if you don't plan on using encoders on your first robot

and waterproof and dustproof IP66 protection grade

The capacitive touchscreen controller uses I2C but you can share the I2C bus with other I2C devices

Adafruit Wide-Range Triple-axis Magnetometer - MLX90393 STEMMA QT SF_AVR 4GHz ultra low-power wireless communicationMeasure the invisible magnetic fields that surround us, with this wide range magnetometer. The MLX90393 is a wide range magnetic field sensor, that can measure 16 bits in ranges from 5mT up to 50mT in all 3 axes. Compared to most magnetometers, this gives a huge range, which makes it excellent for detecting magnets and magnetic orientation, rather than the Earth's magnetic field. (Magnets have a much stronger field that overwhelms most magnetometers
