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.

The SparkFun Audio Codec Breakout - WM8960 is a low power, high quality stereo codec with 1W Stereo Class D speaker drivers and headphone drivers.

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.

The SparkFun Analog MEMS Microphone Breakout makes it easy to work with the Vesper VM2020 analog microphone. The VM2020 is an ultra-high Acoustic Overload Point (AOP), high dynamic range, differential analog output piezoelectric MEMS microphone.

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.

This tutorial will go over how to use an ESP32 microcontroller to connect to u-blox Thingstream and PointPerfect over Internet to push correction data to a high precision GNSS.

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.
