The SparkFun LiPo Fuel Gauge - MAX17043 connects your LiPo battery to your project and uses a sophisticated algorithm to detect the relative state of charge and direct A/D measurement of battery voltage.

Lithium-Ion Polymer (LiPo) batteries are a favorite of ours. Very light weight and some of the highest energy densities available.

The SparkFun GNSS Correction Data Receiver - NEO-D9S is a satellite data receiver for L-band correction broadcast. It can be configured for use with a variety of correction services including u-blox's PointPerfect satellite GNSS augmentation service.

Connect the SparkFun AzureWave Thing Plus to the cloud to grab current weather conditions in your area, post sensor data to a server, control the lights in your next home automation project, or even calculate the Fast Fourier Transform (FFT) of an input audio signal!

The SparkFun ESP32 Thing Plus enjoys all the amenities of the ESP32 Thing, but with a few added sparkles.

In this tutorial, we will expand on the SIK for RedBot to control a robot wirelessly with XBee radios!

The safety scarf is embedded with LilyPad Hardware and a ribbon of LEDs.

The SparkFun Adjustable LiPo Charger is a single-cell lithium polymer (LiPo) and lithium ion battery charger.

In this tutorial, we will go through the step-by-step process of building this project.
