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.

Installing an Arduino Bootloader

This tutorial will teach you what a bootloader is, why you would need to install/reinstall it, and go over the process of doing so.

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.
  • If you use a 5V FTDI it will put 5V on the VCC line. If you use a 3.3V FTDI than 3.3V will be on the VCC line. I believe the maximum voltage the ATMega328 can handle is 6V (absolute max, not recommended) so the IC is fine. Basically the 3.3V designation of the board is the value of the voltage regulator and when the board is powered through the regulator the I/O voltage of the controller. In other words if you put 5V on VCC than you will just have a Pro Mini running at 5V. As long as you don’t have components that will fry at 5V connected to the board everything should be fine.

  • Yes. The Pro Mini is actually an official Arduino board so everything is fully supported in the IDE. I believe this is the only official Arduino board to use these pins and the ATMega328 PTH version does not have them, so very old versions of the IDE might not support these pins, but any IDE from the past 3 years (since this board was released) definitely will.

  • Because each item and collaborator relationship is different there are no generic terms and conditions. If you have a product that you want to submit, go for it and in your submission ask what type of terms we are offering. Make sure you include what you plan on doing and what you expect us to do as well since that is one of the biggest factors. Specifically things like firmware, revisions and techsupport. If you have any other questions please email techsupport@sparkfun.com directly.

  • Arduino Day is tomorrow, sale prices will only show up then.

  • They aren’t. They will only show up on Arduino Day (tomorrow).

  • Except this isn’t an Uno R3 compatible board. It is the official Uno R3 meaning 1. We don’t really determine the prices 2. This product officially supports the Arduino environment and IDE. Everyone makes clones, and can often make them cheaper (especially if they are in China and/or do not support our friends at Arduino). We even make our own clone, but you will always pay more for the original than for a clone.

  • Hi, please email techsupport@sparkfun.com and they can help you out as well as verify our current stock. Thanks.

  • 2 main reasons. First is that the sales were not that good. But more importantly the actual SPOT module kept changing. I’m not sure the final end user product changed, but the PCB design and test points we were using did. It wasn’t worth it to try to keep up (see point number 1).

  • I don’t think we’ve ever intentionally used this around dogs. But we have used these in the building, and with 40ish dogs here on a daily basis we’ve never had problems.

  • Hi, it looks like we can no longer get these from LeafLabs so we will not be getting any more in. Take a look at the MBed, Teensy 3.1 and the Teensy LC if you are looking for a nice ARM board, as well as keep checking back, we are starting to get more ARM boards in our catalog.
