SKU: SF-BOB-00716

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...

SKU: SF-BOB-13021

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...

SKU: SF-COM-16988

The SparkFun QwiicBus EndPoint is the fastest and easiest way to extend the range of your I2C communication bus. The breakout uses NXP’s PCA9615 IC, which converts the two default I2C signals into four differential signals, two for SCL and two for SDA. The differential signals are sent over an Et...

SKU: SF-KIT-17250

The SparkFun QwiicBus Kit comes with everything you need to get started with the SparkFun QwiicBus system in one handy package. The kit includes two QwiicBus EndPoints, one MidPoint and two 3ft Ethernet cables. The SparkFun QwiicBus EndPoint is the fastest and easiest way to extend the range of ...

SKU: SF-BOB-10124

This is a breakout board for the SP3485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps. This board requires a very low amount o...

SKU: SF-BOB-13878

The SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard four-wire Wheatstone bridge configuration. If you open up an electronic bathroom scale, you’ll find a large rat’s nest of wires. The Load Sensor Combinator was created to combine the 12 wires foun...

SKU: SF-COM-18000

The SparkFun QwiicBus MidPoint extends the range of your I2C bus using differential signaling over standard Ethernet cables. Based on the NXP PCA9615 IC, it converts I2C signals (SCL and SDA) into four differential signals, enabling reliable communication over distances up to 100 feet (30 m) whil...

SKU: SF-BOB-09822

This is the newest revision and fixes issues with the last board. This breakout board pairs an SP3485 RS-485 transceiver with an FT232RL USB UART IC to convert a USB stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transm...

SKU: SF-PRT-00643

These are simple through-hole RJ45 sockets with PCB mounting posts. These 8-pin connectors are commonly used in conjunction with Cat5, Cat5e, and Cat6 Ethernet cables. Because Ethernet cable is so ubiquitous, these are awesome for projects where you need to string a lot of modules together ove...
