This is a simple, very common rectifier diode. Often used for reverse voltage protection, the 1N4001 is a staple for many power, DC to DC step up, ...

Solenoids are basically electromagnets: they are made of a coil of copper wire with an armature (a slug of metal) in the middle. When the coil i...

This is a Micro SD(TF) module from DFRobot. It is compatible with TF SD card (commonly used in Mobile Phone) which is the most tiny card in ...

This is your tried and true white solderless breadboard. It has 2 power buses, 10 columns, and 30 rows - a total of 400 tie in points. All pins ...

Dip sockets for all your prototyping needs. If you’ve ever had to de-solder a dip part from a circuit board, you know how valuable these are! Nu...

Single row of 30-holes, female header with swiss round machined pins. These units have very high quality round pins to accept and retain machine pi...

This is the LM317TG voltage regulator, a three-terminal positive regulator with a 1.2V to 37V adjustable output voltage. This adjustable regulat...

These 0.1 μF 100 V ceramic capacitors have many uses, including noise suppression on motors.

LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays. This is a very basic 5...

This simple on-off switch is rated for 20A at 12V but who cares about all that, it looks way awesome. These toggle switches come with those missile...

This is the kind of ¼" stereo jack you might find in home stereos and PA systems. Switched contacts allow you to detect whether or not there ...

This connector is a single-row, 12-pin, straight female header strip designed to match 0.1" male headers.

This little round on/off toggle switch is rated up to 10A at 125VAC and can be panel mounted in a 20mm diameter hole. It’ll also look pretty sli...

Sometimes a simple analog control device can be the perfect tactile solution for your project, but they can be surprisingly hard to come by. Luc...

This connector is a double-row, 80-pin (2×40), straight male header strip that can be cut or broken into smaller strips.

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 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...

This is an SMD 12mm square SPST button. What we really like is the large button head and good tactile feel (it ‘clicks’ really well). This button i...
