65 flexible stranded core wires with stiff ends molded on in red, orange, yellow, green, blue, brown, black and white. These are a major improvement over the "box of bent wires" that are sometimes sold with breadboards, and faster than stripping your own solid core wires. Makes breadboarding super fast. Approximately 65 wires in a mix of colors 48 short wires 4.5" (120mm) long 8 medium wires 5.5" (150mm) long wires 4 long 7.5" (190mm) long wires...

Handy for making wire harnesses or jumpering between headers on PCB's. These premium jumper wires are a little over 6" (150mm) long and come in a 'strip' of 40 (4 pieces of each of ten colors). They have 0.1" sockets on either end and fit cleanly next to each other on standard-pitch 0.1" (2.54mm) header. We recentlty updated these so they are in a 'ribbon strip' instead of individual wires. You can always pull...

Perfect for bread-boarding, free wiring, etc. This box contains 6 spools of solid-core wire. The wire is easy to solder to and when bent it keeps its shape pretty well. We like to have a few spools of this stuff around which is why this set is quite nice! We suggest picking up wire strippers to match. Wire gauge is 22 AWG which we've found is the best all-around gauge, it works best with breadboards and perfboards but also fits in terminal...

Imagine terminal blocks that are cut out of one solid piece of brass, designed to distribute power. Well, that's what we have here! These machined bus bars are for when you want to distribute power through a project, we think they are ideal for robots and LED pixel grids where you have tons of current and a lot of loose wiring to control Each bus has 7 holes bored out of a chunk of brass. There are screws that can cinch down any number of wires....

These are like the fancy electronics equivalent of the wire nuts electricians use to bind wires together. They are a lot easier to use as well! Each block connector has a metal block inside and five levers that snap open and close to bind stranded/solid-core wire. No screwdrivers required! They're super handy for free wiring and can handle up to 20A at 300V with UL listing so you can also use them for mains wiring. Use any wires from 12 AWG down...

This stuff is called "wire-wrap wire" because it used to be used for wire-wrapping high-speed digital circuits on a special kind of contact board. It's pretty rare to see wire-wrapping in these days of low-cost PCB fabrication but the wire is still really handy for prototyping work. It's extremely thin (30 AWG!) so your wiring wont get bulky, and it is just stiff enough to hold its shape around corners. It's most commonly used for SMT rework...

Connect this to that without soldering using these quick terminal blocks. They allow connecting of two sets of four wires together using just a flat-head screwdriver. These are UL rated to carry up to 15 Amps, so they're great for high current LED strips! Can be used with wires from 14AWG to 22 AWG

These jumper wires come with a twist! Instead of going from 0.1"/2.54mm pitch headers to breadboard or something like that, these are 2.54mm to 2.0mm ! Handy for making wire harnesses or jumpering to annoying 2mm-pitch connectors, these premium female-female jumper wires are around 8" (200mm) long and come in a 'strip' of 40. Each pair of wires has 2 pieces of 2.54mm (.1") socket on one end and a single 2x2.00mm...

You'll find these handy 2-pin 0.1" spacing pig-tails to be quite helpful when wiring up your project. The connector end snaps cleanly into 0.1" spaced header (and fits neatly side by side on 0.1" spacing as well). We think this would be especially useful when paired with our PWM driver breakout, to control 16 PWM LEDs that are wired, but there's probably a dozen other uses. Come in a pack of four cables, 12 inches long,...

Kiss those days of heat-shrink, melted jacketing and clumsily-arranged third-hand tools goodbye! Go 'cold splice' with these snap-able plastic splices for fast connections. Use with any 22-26 AWG solid core wire and slip them into the plastic splice so that they slide into the metal teeth. Then squeeze down with parallel-jaw or slip joint pliers - don't use needle-noses, they have too much angle and not enough force. We also like using our...

If you are doing biomedical instrumentation or maybe RF work or just need to get signal from here to there, cleanly, you will love this cable! It's extremely thin and flexible coax, only 1.2mm in diameter, but has a standed inner core, plastic insulator and over-shielding. Normally you'd have to pick up a spool of 100 ft or more, but now you can get about 10 ft, just enough for your project.

When alligator clips and even scope probes are too large, IC hooks come to the rescue! These fine clips are very nice, and come in a set of 9 colors (black, brown, red, orange, yellow, green, blue, violet, gray). They provide a nice strong grip on SOICs, TQFPs, anything with 0.6mm pin pitch or larger. The hook is made of strong gold-plated 'piano wire', and there are angle connectors so that you can slip these onto your Saleae Logic probe cable...
