To make life easier so you can focus on your important work, we've taken the

LSM303AGR 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!). We've even included SparkFun

qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need

to solder! Just wire up to your favorite micro and you can use our

CircuitPython/Python or Arduino drivers to easily interface with the LSM303 and

get compass measurements ASAP.

It's fully assembled and tested. Comes with a bit of 0.1" standard header in

case you want to use it with a breadboard or perfboard. Four 2.5mm (0.1")

mounting holes for easy attachment.
