Here at SparkFun, we refuse to leave 'good enough' alone. That's why we're adding to our line-up of Arduino-compatible microcontrollers once more! The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface. This tiny little board does all of the neat-o Arduino tricks that you're familiar with: 9 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as...

Always, always, always wear eye protection while soldering. This is a golden rule we all know but sometimes overlook. Luckily, with these SparkFun Safety Glasses you'll have a pair of lightweight, economical, and stylish lenses to protect your precious peepers. Each pair of these safety glasses removes the SparkFun Geek logo from the lens and adds a single SparkFun flame to the left temple arm. We use these for eye protection in our production lines and classrooms here at SparkFun HQ!...

This is a low-cost, basic SOIC breakout boards. This custom PCB will interface a standard SOIC package IC to 0.1" headers, which are easier to work with and integrate well with breadboards. There is DIP-standard 0.6" spacing between the two rows of pins. 40 Pin break-away headers are perfect for use with these custom PCBs. Machine pin headers may be a better option for IC sockets.

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be and will result in a lower resistance, and a higher SIG out. To get the SparkFun Soil Moisture Sensor functioning all you will...

This is the Large SparkFun Solder-able Breadboard. A bare PCB that is the exact size as our full-size breadboard with the same connections to pins and power rails. This board is especially useful...

This is the Large SparkFun Solder-able Breadboard. A bare PCB that is the exact size as our full-size breadboard with the same connections to pins and power rails. This board is especially useful for preserving a prototype or experiment you just created on a solderless breadboard by soldering all the pieces in place. The large solder-able breadboard also includes real estate for screw terminal connectors and a trace down the center gutter for ground. Documents: Schematic Eagle Files Hookup...

The SparkFun Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once. The envelope output allows you to easily read amplitude of sound by simply measuring the analog voltage. Gain can be adjusted with...

8, 16, 20, and 28-Pin SSOP to DIP break out boards. The footprint was rotated to accommodate different width SSOP devices and can be used with any pin count up to 28 pins. Designed to be used with...

8, 16, 20, and 28-Pin SSOP to DIP break out boards. The footprint was rotated to accommodate different width SSOP devices and can be used with any pin count up to 28 pins. Designed to be used with 0.65mm pitch devices but can also be used with 0.025" pitch devices (comes out to ~0.635mm). We've made these 0.635mm devices fit just fine. Can be used with packages that have a lead span of .230" up to .350". 40 Pin break-away headers are perfect for use with these custom PCBs. Machine pin headers...

The SparkFun TeensyView brings you an easy way to add a small, white-on-black OLED to your Teensy development board. The 128x32 monochrome display is controlled with the popular SSD1306 IC, and is a great way to display debug information and to visualize data without the need for a serial terminal. The board matches the Teensy 3 form factor perfectly, and was designed from the ground up to be as flexible as possible while still being able to nest down into a low-profile addition for the...

The SparkFun Thing Plus - RP2040 is a low-cost, high performance board with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. Besides the Thing Plus or Feather footprint (with 18 GPIO pins), the board also includes an SD card slot, 16MB (128Mbit) flash memory, a JST single cell battery connector (with a charging circuit and fuel gauge sensor), an addressable WS2812 RGB LED, JTAG PTH pins, four (4-40 screw) mounting holes, and our signature Qwiic...

Are you frustrated with the lack of dexterity from most third hands? The SparkFun Third Hand gives you the ability to hold a board between two alligator clips on two flexible arms with multiple points of articulation. The arm's wide range of articulation gives you access to any angle of the board that you are currently working on, making soldering that much easier. The SparkFun Third Hand also won't move around while you work thanks to a heavy aluminum base supporting the arms. Even though we...

This is the SparkFun "Time-of-Flight" Range Finder, a sensor board for the VL6180 distance sensor. Unlike most distance sensors that rely on reflected light intensity or reflected angles to determine range, the VL6180 uses a precise clock to measure the time it takes light to bounce back from a surface. This affords the ToF Range Finder and VL6180 a great benefit over other methods because it can be much more accurate and more immune to noise. Does this technology sound familiar? Well it...
