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.

This tutorial will teach you what a bootloader is and why you would need to install or reinstall it. We will also go over the process of burning a bootloader by flashing a hex file to an Arduino microcontroller.

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.
  • Fixed, thanks for the heads up.

  • Fixed, thanks for the heads up.

  • The migration document mentions it on page 8. It is fairly brief, but does state that it is on D7. The full datasheet should have more information as well (page 185).

  • I'm sorry about that. Please double check your spam folder (sometimes emails responses from techsupport end up there). They usually should get back to you in a day or 2, but I'll make sure they got your email.

  • Sorry, we don't have the ability to swap out parts in a kit. I believe everything except the water bottle is available to purchase separately though.

  • This does not require the internet, you connect directly over your network via a browser for most of the features. The SDR does require software (Power SDR). I believe Power SDR is a third party so you should be fine if the company goes defunct

  • Thanks for the feedback and your first ever comment. We do understand that this is a fairly expensive piece of equipment, but it also can replace quite a few expensive items. This is geared more towards the ham community more than the maker community (there is some overlap, but the ham community also works with higher priced components). As for the test leads, I'm really not sure about that one. That was a decision by the manufacture, but we figured that people would want them so we are carrying them as well. But we do realize this product isn't for everyone (or even every Extra class ham operator).

  • I understand. We liked them as well, but ran into a few issues with our supplier on these. Maybe sometime in the future we'll be selling Hakkos again (probably a new version at that point).

  • Since both the Pro Mini and the Uno/Redboard use the ATMega328 the pin usage is the same. While the Redboard does bring out the ISP header those pins just go to D11-D13 (but on a Lenardo for example they would go to different pins, making that port consistent). In other words since D11-D13 are the SPI pins on the ATMega328, those are the correct pins for the Uno/Redboard as well as the Pro Mini, and so should "just work".

  • 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.
