Added to your shopping cart. Perfect for running relays and high-power devices up to mA and up to 50V! This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools. Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together.

You might need solder wick or flux. See all skill levels. If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code. Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available.

Sensors or shields will communicate with serial or TTL. If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics. Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type.

Also, you may need a power supply that? We welcome your comments and suggestions below. However, if you are looking for solutions to technical questions please see our Technical Assistance page.

Can I drive these directly from any arduino? Are these capable of switching fast enough to allow pwm? I'm new to reading datasheets According to the datasheet, the "typical" Low-to-High transition takes ns.

H-to-L is typically 20 ns. Round up, call it ns, and you can cycle these darlington pairs at about 5 MHz. In the description, ADD the word transistor so it shows up when you search for a transistor.
