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.

The Pro Micro RP2040 is a low-cost, high-performance board with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. The board uses well known Pro Micro footprint with castellated mounting holes.
