This is a 5V 8-Channel Relay interface board able to control various appliances, and other equipment with large currents. It can be controlled directly by Micro-controller (Raspberry Pi, Arduino,etc.). Features 5V 8-Channel Relay interface board,...

If you're like me, you've dreamed of being a dolphin - smoothly gliding through the water. Using your echo-location abilities to detect tasty fish treats. Until genetic modifications catches up with our desires, we'll just have to make do with this...

Waveshare 8552 - UART Fingerprint Reader, Onboard Processor STM32F205, Commercial Fingerprinting Algorithm, Optical SensorUART Fingerprint Reader is a fingerprinting module designed for secondary development, high-speed for identification, high...

Get the most out of your regulators, transistors and other TO-220 packaged chips by clipping on a heat-sink. Your transistor or regulator may advertise it can handle high currents but when multiplied by the drop voltage, the Wattage may be too high for...

If the product is out of stock - please consider the alternative product. This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to...

Adafruit 996 - Brass Liquid Solenoid Valve - 12V - 1/2 Inch G / BSP Thread Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening, aquarium, or pool project. There are two...

Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great accompaniment to the...

Not just a simple breakout board, this microSD adapter goes the extra mile - designed for ease of use. Onboard 5v->3v regulator provides 150mA for power-hungry cards 3v level shifting means you can use this with ease on either 3v or 5v...

Description: This is a simple six wire cable. Great for jumping from board to board or just about anything else. There is a 6-pin JST RE connector on both ends. These are simple jumper wires used on standard 0.1" breakaway headers. Dimensions: 12" length

This is the Magnetic Door Switch Set, a small reed switch assembly specifically designed to alert you when doors, drawers, or any other aperture opens. These types of switches are primarily used in home security systems. One half of the assembly set on a...

Description: Low profile 3.5mm stereo audio jack. Documents: Audio 3.5mm Jack Datasheet

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 protect the 3.3V device from 5V. We do have some other...
