He told you “Go West, young maker!” – but you don’t know which way is West! Ah, if only you had this triple-axis magnetometer compass module. A magnetometer can sense where the strongest magnetic force is coming from, generally used to detect magnetic north.
We based this breakout on a popular and well loved magnetometer, the HMC5883L. This compact sensor uses I2C to communicate and its very easy to use. Since it’s a 3.3V max chip, we added circuitry to make it 5V-safe logic and power, for easy use with either 3 or 5V microcomtrollers. Simply connect VCC to +3-5V and ground to ground. Then read data from the I2C clock and data pins.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
