We all know that women are not only a minority in technical fields, but are often not encouraged to go into such fields. Here are a few ways to encourage and support the girls/women in our lives who are interested in technical fields.

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.
  • This board does come configured as 5V but can be modified to be 3.3V. Additionally I’ve never had an issue programming a 5V Pro Mini from a 3.3V FTDI. While technically the chip is out of spec at 3.3V/16MHz we actually sell a product that runs at that without an issue. Unless connected components require 5V everything should work fine. Thanks for the heads up, we’ve updated the description.

  • If you are looking to distribute these in the EU I recommend getting a hold of our distributor services team (dservices@sparkfun.com) and they might be able to help you out.

  • For those unsure about what time this is (time zones and daylight savings make for weird calculations).


    Countdown number 2

  • Nothing in our processes makes us believe that these are not RoHS compliant. We use Lead Free solder on all our assemblies and most components sold now a days are RoHS compliant. That being said we don’t have the paperwork to prove these are RoHS compliant and so we’ve chosen not to mark it as compliant. I’ll look into the LilyPad LEDs, but my guess is they were marked as RoHS a long time ago when we operated under a slightly different policy. If you have any other questions feel free to email our support staff.

  • It is possible they have produced this or previous versions in black, but this is an image of the units we got in stock.

  • Not likely. I’ll see what I can do, but we order these from a company that does swag and specializes in printing your logo on things. They are much less concerned with the technical specs.

  • This is mostly an issue of scale. We still have to pay for someone to go get one off a shelf, put it in a bag/box, etc. Not to mention the actual bag/box. If you just need 1 or 2 for a project then grabbing one makes sense. If you need a lot then there are definitely better options for you including Amazon.

  • It is the same just without the case.

  • The SparkX process is different in many ways other than quantity of boards built. They also have a lot less constraints on what they can and can’t do and that can be reflected in their pricing. For example all SparkFun boards come fully tested with full documentation and live technical support while SparkX boards don’t come with any guarantee. When doing pricing we calculate what pricing should be and then compare it to SparkX and try to find a happy medium. Sometimes pricing goes down, sometimes it goes up, but from what I can tell $200 is still a pretty good price for an RTK GPS.

  • I was hoping they were and we could use up all those silly connectors but they are not. One is 70 pin, the other is 80 pin, but they are the same manufacture and the same series.
