The What, How, Why, and When of Field Programmable Gate Arrays, aka FPGAs

Get started with the MAG3110 3-Axis Magnetometer and learn how to make your own digital compass that senses the Earth's magnetic fields.

We can use the parts and concepts in the SparkFun Invetor's Kit to make a primitive keyboard instrument.

Freescale’s MMA8452Q is a smart, low-power, three-axis, capacitive micro-machined accelerometer with 12-bits of resolution. It’s perfect for any project that needs to sense orientation or motion. We’ve taken that accelerometer and stuck it on a Qwiic-Enabled breakout board to make interfacing with the tiny, QFN package a bit easier.

A hookup guide to get started with the BME68x Environmental Sensor from Bosch. Monitor the air quality, temperature, humidity, and barometric pressure with this Qwiic sensor!
