How to Use a Breadboard

May 14, 2013

Welcome to the wonderful world of breadboards. Here we will learn what a breadboard is and how to use one to build your very first circuit.
  • Stencils can be tricky. A few years ago I needed on and opted to use our laser cutter. The trick was finding a material that the laser could cut (not metal), wouldn’t melt (not plastic) and wouldn’t instantly disintegrate with the wet solder and force from the spreader. I ended up using a spare photo I had (matte finish). As long as I ‘engraved’ the image a few times and didn’t try to cut it, it worked out pretty well for a few runs. The biggest issue seemed to be that the solder was sticking to the stencil more than on a typical stencil. We did successfully get a FTDI done, but this method might not work for anything finer pitched. It would be worth seeing if glossy paper or applying finishes would help any.

  • Thanks for the feedback. The current microB footprint uses the little plastic pins as well as vias on the pads. Having both of these has increase reliability over the past few years, but we are still looking into making these even sturdier.

  • That’s one of the reasons for the Power block. It comes without the battery so you can add your own and physically put it wherever you want. Also the battery is attached with sticky tape, it is possible to remove it, just be careful.

  • You are more than welcome to boycott SparkFun, but I do have a few comments for you.

    1. You can always find things cheaper, and usually from China. We don’t pretend otherwise. But you often loose out on support from the manufacture as well as supporting those who’ve designed the products. Sometimes what you want is cheap, sometimes what you want is support.
    2. We try to avoid insane markups. Not only is the cost of business in China cheaper (cheaper labor, cheaper shipping on parts already coming from China etc.), but we tend to be smaller and not able to negotiate the lower prices. For the most part the markup goes to shipping products in from China, rent on the building, paying US wages for production and testing, etc.
    3. We’ve always encouraged customers to buy bulk components from more appropriate places. Most of our resistor and capacitor pages actually list the Digikey part number. If it doesn’t feel free to email out techsupport department and they can probably get that number for you. We sell these parts for convenience if you only need a few, but we have no intention of competing with Digikey or Mouser on these types of things. There are definitely times it makes more sense to buy parts from a more specialized or appropriate place and we encourage you to do so.

    As for the boycott, personally I understand your feelings. This post has unfortunately brought out a lot of disrespect and division within our community. I do not have the ability to issue a SparkFun backed apology, so I will offer you what I can and say I deeply regret the disrespect and division this post has caused in our community. I will respect your decision and wish you the best of luck regardless of your beliefs or where you shop.

  • fixed

  • I am sorry we seemed to have lost a loyal customer. I respect your decision and wish you luck in all your future hacking.

  • We have the right to disrespect, but that is very different than disobey. I do not advocate disobeying the law, but we can not cause change if we are not allowed to disrespect. Disrespect for the law is not only allowed but encouraged under the First Amendment (which allows freedom of speech for our non-US readers).

  • I am sorry you regret doing business with SparkFun. While I understand your frustrations, the right to disrespect the rule of law is an American value that we respect. As it has been said, “I disagree with what you say, but will defend to the death your right to say it.” If you want us to cancel your account please email customer service and they can do that, and I will be sorry we have lost a customer.

  • Thanks for the feedback. This should all be fixed and uploaded.

  • Sorry, took me a while to pull up and update files. Updated.
