For storing small parts (especially SMT/SMD components), these little modular boxes are ideal. They have individual clear pop-open covers so you ca...

This light ball caster uses a 3/4″ diameter plastic ball. The height of the assembled kit ranges from 0.9″ to 1.2″, depending on the combination of...

This DC power jack/connector is just like the other one that we carry except that it’s terminated with breadboard-friendly pins instead of wide sol...

This is a 3-terminal microswitch two pack, each equipped with a 20mm offset lever actuator. These switches have a great ‘clicky’ sound to them w...

For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a ...

Check out these big 10mm through-hole LEDs! The opaque epoxy package causes these LEDs to have a soft, diffuse glow.

EL wire, or electroluminescent wire, is a flexible wire coated in phosphor. Apply the appropriate voltage and it lights up! Each EL wire looks a lo...

These male pins can be crimped on 22-28AWG wires and snapped into our crimp connector housings to create custom cables that are compatible with ...

Keep your electronics from going barefoot, give them little rubber feet! These small sticky bumpers are our favorite accessory for any electronic k...

We know this looks like a lot of our other LEDs, but it’s not! This is a PTH Addressable RGB LED with a WS2812 control IC built right into the LED....

This potentiometer is a two-in-one, good in a breadboard or with a panel. It's a fairly standard linear taper 100K ohm potentiometer, with a gri...

These are your standard 9 Volt alkaline batteries from Rayovac. Don’t even think about trying to recharge these. Use them with Arduinos or with a v...

This is a 3.5mm TRRS SMD audio jack. TRRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boa...

Most of our customers love using the Arduino for prototyping, design and invention but find themselves stuck when trying to connect the Arduino ...

This is a simple two wire cable. Great for jumping from board to board or just about anything else. There is a 2-pin JST connector on one end, bare...

We all know that you can never get too many LEDs. Don’t worry, we’ve got you covered. This is a pack of 25 LEDs all conveniently packaged in a nice...

This is a glass ferrule type fuse. It fits great with our 5mm fuse clips. The fuse is rated for 125VAC, up to 5A. Fuses are pretty simple, if more ...

This is a 2-pin, through-hole PH series JST connector. The pins are spaced by 2mm. We really like the solid locking feeling and high current rati...
