This project provides the current date and time using GPS satellites. Depending on your display, you can draw the time as a digital or analog clock. Or even configure the clock to read military time, adjust the clock for your time zone, or automatically adjust the time for daylight savings time!

This tutorial will focus on setting up your own fixed antenna on your roof or other fixed structure and configuring a minicomputer to serve that data over the internet where it can be accessed by WiFi or more commonly, from a cellular phone or modem.

In this tutorial we'll build a basic magnetic levitator. This guide will go over some of the theory, how to use a magnetic field sensor, and how to use one to build a basic levitation circuit.

In this tutorial, we'll walk you through using the SparkFun Audio Player Breakout in combination with the Qwiic Twist to let you select and play tracks from a microSD card. It's a compact and powerful way to add audio interactivity to your prototype using simple I2C and serial connections.

The MicroMod RP2040 Processor Board is a low-cost, high-performance board with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. The board takes advantage of the MicroMod M.2 connector to easily swap out processor boards on carrier boards.

The SparkFun MicroMod ESP32 Function Board adds additional wireless options to MicroMod Processor Boards that do not have that capability. This special function board acts as a coprocessor that takes advantage of Espressif's ESP32 WROOM to add WiFi and Bluetooth® to your applications.
