Punch in your secret key into this numeric matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3x4 grid. It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly...

Diffused 5mm tri-color LEDs with separate red, green and blue LED chips inside! Nice indicator, and fun to color-swirl. 60 degree viewing angle.  These are Common-Anode type which means you connect one pin to 5V or so and then tie the other three...

Designed for use with Raspberry Pi Model A+/B+/Pi 2/Pi 3/Pi 4 only! No soldering required!This Cobbler is in a compact shape, which is the least bulky way to wire up.  The Cobbler can plug into any solderless breadboard (or even a...

If you want to heat sink a SoC, motor driver, linear regulator, FET or other surface-mount package part, you might find yourself struggling to find a good heat sink. These little extra-small mini heat sinks are easy to use and give you an extra thermal...

These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128x32 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes...

HDMI Male to Male Flat Cable, Nickel Plated, 0.3 meter Connect two HDMI devices together and save space with this basic flat HDMI 1.4 cable. It has nice molded grips for easy installation, and is 1 foot long (~30 cm). This cable is...

These strips have 30 digitally-addressable pixel LEDs per meter and are very affordable and are only 12.5 mm wide, 10 mm if you remove the strip from the casing. This is the strip with black flex PCB, its identical to the white 30 LED/meter except it has...

This Wifi Shield board is based on Serial to Wi-Fi module Wizfi210 from Wiznet and it is compatible with Arduino and its clones. The Wifi Shield offers you a quick, easy, and effective way to add Wi-Fi capabilities to Arduino. The Wifi Shield...

This prototyping shield is the best out there (well, we think so, at least), and now is even better with Version R3 - updated for the most compatibility with just about all the Arduinos! It works with UNO, Mega, Leonardo, NG, Diecimila, Duemilanove,...

Nothing makes a project harder to maintain than a lot of loose wiring. That's why we like to use terminal blocks whenever making PCB-to-Wire connections. These particular 3.5mm terminal blocks are our favorite: big enough for a range of wire gauges, easy...

The AM2302 is a wired version of the DHT22, in a large plastic body. It is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on...

Use this shield to add capacitive touch keys (like bananas or play doh!!) to your Arduino Uno. The popular Makey Makey product works this way. Specifications Suitable for 2009 Uno UNOR3 LEONLADO controller. Working voltage: 5V Interface: USB male...

This is an Arduino-comptabile microcontroller ATmega328 running at 16MHz with external resonator (0.5% tolerance) 0.8mm Thin PCB USB connection off board Supports auto-reset 5V regulator Max 150mA output Over current protected Weighs less than...
