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.

Bluetooth-enabled technology has become ubiquitous in today’s world. The average person would be hard pressed not to use Bluetooth during their daily activities. Although Bluetooth may seem difficult to work with, it’s fairly straightforward to start incorporating Bluetooth into your projects.

In this tutorial, we’ll teach you how to get started using Bluetooth in your projects by sending sensor data between multiple SparkFun Thing Plus ESP32 Wroom USB-C devices.

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

The SparkFun ESP32-WROOM Thing Plus (USB-C) enjoys all the features of our previous ESP32 Thing Plus (Micro-B) boards, but with a few improvements.

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 RP2040 mikroBUS™ Development Board is our latest RP2040 microcontroller (MCU) ‎development board.

The SparkFun Artemis Global Tracker provides a powerful tracking system combining remote short messaging via the Iridium satellite network with GPS tracking and environmental sensing all powered by the SparkFun Artemis module.

The SparkFun OpenLog Artemis (OLA) is a versatile, open source data logger that comes preprogrammed to automatically log a wide variety of data from a large number of sensors. And here’s the best bit You can do all of this without writing a single line of code!

The Qwiic Motor Driver takes all the great features of the Serial Controlled Motor Driver and mini-sizes them, adding Qwiic ports for plug and play functionality.

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