The SparkFun Multiplexer Breakout provides access to all pins and features of the 74HC4051, an 8-channel analog multiplexer/demultiplexer. The 74HC4051 allows you to turn four I/O pins into eight multifunctional, individually selectable...

The SparkFun ESP32 Thing is a comprehensive development platform for Espressif’s ESP32, their super-charged version of the popular ESP8266. Like the 8266, the ESP32 is a WiFi-compatible microcontroller, but to that it adds support for...

These motorized sliders are very cool. Each is essentially a standard slide pot which is belt-driven by a small motor. The slide contains two separate 10k linear taper potentiometers so that you can use one as servo-feedback in order to...

This is the same accessory cable found in the LIDAR-Lite v3. The LIDAR-Lite Accessory Cable is terminated with a simple 6-pin JST at one end and a bare wire pigtail at the other. You can use this cable as a replacement to the one you are...

2.4GHz Duck Antenna 2.2dBi with Reverse Polarized - SMA RF connector. Perfect for prototyping with our RF ICs. 50 ohm impedance. 4" long. The FCC is moving towards Part 15 compliance. All this means is that all the SMA RF connectors are...

Alligator clips (or Crocodile clips, if you prefer) are likely to be the most useful thing on your workbench besides the workbench itself. Whether you’re just trying to make a few quick connections to test your circuit or having trouble...

This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. Pressing lightly, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does...

The SparkFun Mini GPS Shield equips your Arduino Mini with access to a GPS module, µSD memory card socket and all of the other peripherals you’ll need to turn your Arduino into a position-tracking, speed-monitoring, altitude-observing...

The SparkFun Serial Controlled Motor Driver (SCMD) is a DC motor driver that’s been designed to drive small DC motors with ease. The SCMD is designed to emulate a typical register-based device in operation. It can be commanded by UART, I...

The Bus Pirate v3.6a, created by Ian Lesnet , is a troubleshooting tool that communicates between a PC and any embedded device over 1-wire, 2-wire, 3-wire, UART, I 2 C, SPI, and HD44780 LCD protocols - all at voltages from 0-5.5VDC. This...

Need range? 2.4GHz Large Duck Antenna 5dBi with Reverse Polarized - SMA RF connector. Perfect for prototyping with our RF ICs. 50 ohm impedance. This antenna mates nicely with the Reverse Polarized SMA Connector. Dimensions: 0.5x7.7"

At SparkFun we use many Arduinos and we’re always looking for the simplest, most stable one. Each board is a bit different and no one board has everything we want, so we decided to make our own version that combines all our favorite...
