This USB breadboard power supply kit provides power source from any USB port and outputs a fuse protected and regulated 3.3V. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled 5V/GND 3.3V/GND plug directly into the power lines.
Holds battery in place with friction. The metal housing connects to the positive side of the battery and the PCB pad underneath is connected to the negative side.
This 9V battery holder allows your battery to snap in tight and holds it in place and has a DC plug output connector. Great for situations where you don't want the battery just hanging. It also has three mounting holes so you can attach it securely to your enclosure.
PCB mount clip to hold a AA battery. Sold in single units, you'll need two. These work great for small, low power applications that need a battery to run. Low cost and easy to use!
Simple 4 Cell AA Battery holder with 5" leads with polarized termination, square configuration.
This 2xAA battery holder with removable sliding cover and on/off switch puts a nice finishing touch on your battery powered project.
This 2xAA battery holder with a removable sliding cover and On/Off switch puts a nice finishing touch on your battery powered project.
This smaller solenoid is designed to work directly with 5V which makes it a great match for embedded projects.
This is a carbon fiber safety cover protects a toggle switch from accidentally being turned on.
This is a package of ten 6 inch single female to female jumper wire set good for prototyping wire connection. These are 155mm long jumpers with female connectors on both ends.
This is a package of ten 6 inch single male to male jumper wire set good for prototyping wire connection. These are 155mm long jumpers with male connectors on both ends.
This 0.5W, 8Ohm speaker is only 40mm in diameter and just over 4mm thick. If you want to get some sound out of your project but have a tight space budget, this is a good way to do it.
This large matrix has 64 Red, 64 Green and 64 Blue individual LEDs built into one common cathode housing. Unit comes with a black finish and a opaque LED lenses.
Dimensions: Overall Display: 127 x 101.6 mm (5.00" x 4.00"). Digit Height: 153mm (6.02").
This medium matrix has 64 Red/Green LEDs built into one common cathode housing. Unit comes with a black finish and a opaque LED lenses.
This small matrix has both bright-red and bright-green LEDs built into one common cathode housing.
This is a 12-step rotary encoder with a nice 'clicking' feel. It's breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an encoder has full rotation without limits.
This is a small 12mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces.
A simple SMD slide switch. Perfect for when you need access to a setting or a power switch from the edge of a PCB buried deep within a project. Features: 4V - 300mA. 70mOhm resistance. 10,000 cycle life.
This is QRE1113 breakout board features a digital output, using a capacitor discharge circuit to measure the amount of reflection. This tiny board is perfect for line sensing when only digital I/O is available, and can be used in both 3.3V and 5V systems.
Apply 5V and be shaken by this small, but powerful vibration motor. Works great as an physical indicator without notifying anyone but the wearer.
This Liquid Level Sensor from Milone Technologies is a great way to measure the level of a liquid. It has a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems.
This is a PCB made for the MQ-3, MQ-4, MQ-6 and MQ-7 gas sensors.
