SparkFun Triple Axis Magnetometer Breakout
MLX90393 (Qwiic)
-
It's time to start utilizing the superior magnetometer, and what better way than to throw it onto an easy-to-use breakout board? The SparkFun MLX90393 Magnetometer Breakout is a triple-axis magnetic sensor board capable of sensing very small fields, while still behaving as one would expect during saturation in larger fields (like a nearby magnet). The MLX90393 breakout can be used as a compass sensor but also works well as a non-contact controller, a flow meter with a magnetic impeller, or a linear actuator position sensor. To make it even easier to to get your readings, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

SparkFun LiPo Fuel Gauge
-
LiPo batteries are a great way to power your projects. They're small, lightweight, and pack a pretty good punch for their size. Unfortunately, even the best batteries eventually run low on power and when they do it's often unexpected (and at the worst time). Don't be caught by surprise next time your board suddenly powers-down! The SparkFun LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect relative state of charge and direct A/D measurement of battery voltage. In other words, it tells your microcontroller how much 'fuel' is left in the tank. The LiPo Fuel Gauge communicates with your project over I2C and an alert pin also tells you when the charge has dropped below a certain percentage.

TMD37003 cRGB Color and Proximity Sensor
SEN-36004
-
Fully integrated carrier board designed to get the most out of the TMD37003 cRGB (color with IR compensation) and Proximity Sensor from AMS. This means that the board includes a 1.8V-5V input range LDO and high-speed signal voltage translation on all IO pins. In addition, we've added a high output white LED that is tuned to the light temperature range of the TMD37003 IC. This makes sensing color of close-proximity objects possible, such as in robotic color sorting operations. As on many of our boards, we've included 4-40 sized mounting holes to make installation easy. The IC functions are interfaced via a 0.1" header, which includes power (Vdd and GND), I2C interface (again, fully translated) and a 3.3V input to power the proximity (IR) LED. The on-board LED is turned on with a logic 'HIGH' applied to the LED pin and is powered with Vdd.
