Visualize the invisible world of magnetism in real-time! The SparkFun Magnetic Imaging Tile utilizes a dense 8x8 grid of 64 high-sensitivity Hall-effect sensors to create a live, visual representation of magnetic fields. This allows you to "see" the behavior of magnets, the flow of current in wires, and the fields generated by electric motors. Best of all: this board just got a price drop!

The SparkFun TMAG5273 Qwiic Linear 3D Hall-Effect Sensor provides high-precision data on a magnetic field's presence, strength, and direction across three dimensions. This board is perfect for applications involving magnetic proximity detection, door and window sensing, mobile rotor control, and more - all on a Standard 1-inch by 1-inch Qwiic breakout, or check out the 0.5-inch by 1-inch mini version!

The SparkFun HMC6343 Digital Compass Breakout represents the gold standard in compact, easy-to-integrate navigation. While standard magnetometers can be erratic and difficult to calibrate, the HMC6343 is a fully integrated, high-performance electronic compass module that delivers reliable heading data out of the box. We’ve designed this breakout to make professional-grade navigation accessible for any project, from autonomous rovers to handheld tracking devices.

We've recently released some updated current sensors, including the INA228 and INA237 Qwiic Current Sensors and the ADE7953 Qwiic Non-Invasive Current Sensor and Kit. With these releases, we realized we have quite a few unique sensors that measure and output power data, and it can be confusing to know which sensor is right for you. So let's do a basic overview of electrical current and the most popular current sensors we carry!
