If we could eat headers we'd have them for breakfast, lunch, and dinner.  But we can't : ( So we're making the best of it and selling them! This 2x20-pin strip, right-angle female header is a perfect...

Socket (female) header is like the duct tape of electronics. Its great for connecting things together, soldering to perf-boards or PCBs to allow 22AWG wire or male header to connect, etc. We go...

Need to measure something damp? This epoxy-coated precision 1% 10K thermistor is an inexpensive way to measure temperature in weather or liquids. The resistance in 25 °C is 10K (+- 1%). The...

The eTape Liquid Level Sensor is a solid-state sensor with a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with...

Simple but effective - this breakout board has a CR1220 coin cell battery holder soldered on, an on/off switch and 0.1" pitch breakout pins for easy connecting. Great for powering very low-current...

RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a 'dot' of silicone. The dots are weatherproof and rugged. There are...

This is an inverter for EL wire and tape, similar to our pocket inverters, except it is a brick that takes 12V input instead of 2 AA batteries. This means its good for 'fixed' installations since you...

This is a blank 13.56MHz RFID/NFC keychain fob - often used for keys but also an easy way to tag something. The tag contains a small RFID chip and an antenna, and is passively powered by the...

This is a blank 13.56MHz Classic 'laundry' tag - often used for laundry or identification but also found in other systems where a small proximity card is desired. This one is clear!  The tag contains...

This here is a 10 pack of the classic 1N4001 power blocking diode. These are good for reverse polarity protection (put it between your DC power jack and circuitry to avoid a negative-voltage that...

These 2-wire cables are 16cm long and come as a set.  One side has a 2-pin JST SM type connector plug on the end.  The other side has a matching 2-pin JST SM type receptacle connector...

After a long day out harvesting in the terminal block fields, we've returned with a veritable bounty of these very nice and compact 2.54mm/0.1" terminal blocks in a variety of sizes. Our harvest of...

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and...

A ZIF (Zero Insertion Force Socket) allows you to insert and remove chips easily from an existing circuits. These are often used for chip programmers or when you need to test a chip without damaging...

This is a connector that fits directly to the edge contacts of a BBC micro:bit. The connector has 80 pins, but because of the different widths of the micro:bit edge contacts, some of the micro:bit...

These 3-wire cables are 163mm (6.4") long and come as a set. One cable has a JST SM type connector plug on the end. The other cable has a matching JST SM type receptacle connector. They are good for...

Female header is like the duct tape of electronics. Its great for connecting things together, soldering to perf-boards, sockets for wires or break-away header, etc. We go through these guys real...

Three rows in a right angle header!? Yes! These chunks of 0.1" header has yet-another-row - handy for when you want to connect cables that come in sets of three, like perhaps sensors, or servos...

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to...

These 4-wire cables are 15cm long and come as a set, one side has a JST SM type connector plug on the end. The other side has a matching JST SM type receptacle connector. They are good for whenever...
