This Bi-Directional Logic Level Converter is a breadboard-friendly device that converts between 5V and 3.3V logic.

When you need to switch a lot of power, N channel MOSFETs are best for the job.

0.2A Forward Current, 1V Forward Voltage, Fast Switching Type.

In most Arduino projects, relays are the first choice to drive some large current device. It requires a certain amount of current to drive the internal coil to pick-up...

This tiny logic level shifter features four bi-directional channels, allowing for safe and easy communication between devices operating at different logic levels. It can convert signals as low as 1.5 V to as high as 18 V and vice versa, and its four channels are enough to support most common bidirectional and unidirectional digital interfaces, including I²C, SPI, and asynchronous TTL serial.

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...

This 8-channel USB Logic Analyzer with support for sampling rates of up to 24MHz provides a good while economic option making it a great and easy tool...

If you do anything with electronics, you’re probably already using transistors, but you’re probably using them in large, prepackaged clusters of just one type. The SparkFun Discrete Semiconductor Kit addresses your needs of only needing one or a couple transistors without you needing go and order a single transistor. Inside each kit you will find multiple types of semiconductors including PNP and NPN bipolar transistors, N-channel and P-channel MOSFETs, diodes, adjustable voltage references, and adjustable voltage regulators.

4017 Decade Counter/Divider CMOS IC (Complementary Metal-Oxide-Semiconductor) logic chips are popular due to their lower power consumption, wider range of power supply voltages (3-15V) than those offered by TTL (Transistor-Transistor Logic) and a reduced need for extraneous circuitry, simplifying the design process and reducing circuit board size.

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...

This affordable, ready-assembled robotics controller board is ready to accept your BBC Micro:Bit, battery power (6 to 10V) and motors of your choice to make your own DIY robot. Use a small box, ice-cream carton or similar to house everything and you can build a really affordable robot for your school, coding club or home.

Since the advent of micro:bit, its simple and practical way of programming is widely loved by makers, students and teachers. Its sample design, coupled with a wealth...

micro:bit is a pocket-sized microcontroller designed for kids and beginners to learn coding and electronics, letting them easily bring ideas into DIY digital games...

A rotary switch is a switch operated by rotation. It is often used when more than 2 positions are needed, such as multi-speed control.

This keyboard uses an analog input to read the five key state which saves IO resource for the Arduino. It can be used together with our I/O expansion boards to make amazing interactive project.
