SparkFun RJ45 Breakout
RJ45 connectors are the kind that are used for Ethernet jacks, but they make great general purpose connectors when you need a lot of conductors. This is a small PCB that brings out the pins of the RJ45 connector to an in-line 0.1" footprint. Use with break-away headers for breadboarding or create...
SparkFun RJ45 MagJack Breakout
This is the SparkFun RJ45 MagJack Breakout, a simple board that will provide you with a way to put an ethernet port into your breadboard. The SparkFun RJ45 MagJack Breakout is the same one found in our very own mbed Starter Kit and breaks out each pin from the ethernet jack. This rev of the br...
SparkFun Roller Encoder Breakout - SparkFun Electronics
·
A breakout board for the Panasonic EVQWGD001 roller wheel encoder with press-to-select switch. This tactile input device combines a scrolling wheel with a push button in a compact form factor – similar to the scroll wheels found on automotive steering wheel controls. The breakout provides easy a...
SparkFun Rotary Encoder Breakout - Illuminated (RG/RGB)
This is a clever little breakout board for both the RGB and R/G illuminated rotary encoders. On one side, it breaks out all of the RGB pins to standard, breadboard friendly, 0.1" headers. Turn it over and it has a footprint for the R/G version! Simply solder an encoder down to the board and you’r...
SparkFun Rotary Switch Potentiometer Breakout
The SparkFun Rotary Switch Potentiometer Breakout is a small board the allows you to add resistors to a 10-position rotary switch, turning it into a potentiometer with 10 discrete steps. Multiple applications require potentiometers that are hard to find due to specific resistance values or cus...
SparkFun RP2040 mikroBUS Development Board
The SparkFun RP2040 mikroBUS Development Board is a low-cost, high performance platform with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. Besides the Thing Plus or Feather PTH pin layout, the board also includes a microSD card slot, 16MB (128Mbit) fl...
SparkFun RS232 Shifter - SMD
The smallest and easiest to use serial conversion circuit on the market! This board has one purpose in life - to convert RS232 to TTL and vice versa (TX and RX). This will allow a microcontroller to communicate with a computer. Shifter SMD is powered from the target application and can run at any...
SparkFun RS232 Shifter SMD (No DB9)
A compact RS232-to-TTL level shifter board that converts both TX and RX lines bidirectionally. Powered from your target application's supply voltage, it automatically converts RS232 signals to match — run it at 5 V for 5 V TTL, or at 2.8 V for 2.8 V CMOS TTL levels. Includes TX and RX indicator L...
SparkFun RTK Reference Station
The SparkFun RTK Reference Station is a high-precision GNSS base station designed for surveying, geolocation, and time reference applications. Set up a fixed-location NTRIP server to provide RTK corrections to rovers, or use it as an NTP server for network time synchronisation — all with just a f...
SparkFun Safety Glasses
These were really nice safety glasses. Then we decided to completely ruin them and slap the geek logo on there. Don’t worry, it doesn’t impair your vision… dangerously. Here our photographer, Juan, is helping our receiving guru, TJ, relive his glory days as a teenage heart-throb boy-band fro...
SparkFun SAMD21 Mini Breakout
If you’re ready to step your Arduino game up from older 8-bit/16MHz microcontrollers, the SparkFun SAMD21 Mini Breakout is a great landing spot. The SAMD21 Mini Breakout is a Pro Mini-sized breakout for the Atmel ATSAMD21G18, a 32-bit ARM Cortex-M0+ processor with 256KB flash, 32KB SRAM, and an o...
SparkFun SD/MMC Card Breakout
With SD and MMC memory prices dropping, the time is right for mass storage and datalogging. This breakout board will allow you to breakout the SD/MMC socket to a standard .1" 10-pin header. Perfect for breadboarding and the likes. Board comes fully assembled and tested as shown. Dimensions: 1.3"...
SparkFun Serial Basic Breakout - CH340C and USB-C
This SparkFun Serial Basic Breakout is an easy-to-use USB-to-Serial adapter based on the CH340G and takes advantage of the handy USB-C connector. With USB-C you can get up to three times the power delivery over the previous USB generation at 1.5A and and also solves the universally frustrating di...
SparkFun Serial Basic Breakout - CH340G
The SparkFun Serial Basic Breakout is an easy-to-use USB-to-Serial adapter based on the CH340G IC from WCH. It works with 5V and 3.3V systems and should auto install on most operating systems without the need for additional drivers. The Serial Basic uses the CH340G IC to quickly and easily con...
SparkFun Serial Controlled Motor Driver
The SparkFun Serial Controlled Motor Driver allows you to control up to two DC motors using a serial command interface. The serial interface is easy to use and it lets the user select an individual motor, the direction, and the desired speed constant (up to 10 different speed from stop to full sp...
SparkFun Serial Enabled LCD Kit
Calling this the “Serial Enabled LCD Kit” doesn’t do justice to how cool it actually is. After you’ve assembled this all-PTH kit, you’ll be left with a fully Arduino-compatible development board that just happens to have a white on black 16x2 display built-in. Turns out the ATMega328 is pret...
SparkFun Servo pHAT for Raspberry Pi
Control up to 16 servo motors from your Raspberry Pi over I2C with the SparkFun Servo pHAT. By using I2C for PWM generation, this HAT keeps all your GPIO pins free for other tasks. It also provides a serial terminal connection, so you can set up your Pi without a monitor and keyboard. Power is s...
SparkFun Servo Trigger
The SparkFun Servo Trigger is a compact robotics board that simplifies control of hobby RC servo motors — no programming required. When an external switch or logic signal changes state, the board tells an attached servo to move from position A to position B. Simply connect a hobby servo and a sw...
SparkFun Servo Trigger - Continuous Rotation
The SparkFun Continuous Rotation (CR) Servo Trigger lets you control a hobby CR servo motor without any programming. Simply connect a servo and a switch, adjust the three onboard potentiometers, and the board handles everything — when the switch changes state, the servo transitions between two sp...
