Connector Basics

January 18, 2013

Connectors are a major source of confusion for people just beginning electronics. The number of different options, terms, and names of connectors can make selecting one, or finding the one you need, daunting. This article will help you get a jump on the world of connectors.
  • I’m not sure what’s wrong, either. That response indicates that the device is waking up, responding, and going back to sleep. Do you have external power connected to the board? If you don’t, it’s trying to power it via the TX pin on the FTDI and that’s definitely not okay.

    Power is not connected to the FTDI header because that would bypass the power switching mechanism if you were to connect the load device to that header, as well as possibly contend with the onboard regulator.

  • Well, that depends. You can use it to send a phone number, so if your handset can generate a number somehow, you can certainly capture it and send the command to the phone. No guarantee that older phones will respond to that datastream, however.

  • I’ll suggest it.

  • I prefer them unconnected; it’s easier to make connections than to break them in my experience.

    I do use a lot of wire wrapping with this, and solder blob tracing.

    I had considered some buses on this, but the V-score actually makes that impossible. It will break any copper it crosses and it must go the whole width of the board.

  • It is!

  • It should work fine for that panel. As for changing the charge current, you’ll need to adjust the inductor and possibly the diode, but generally it should be fairly easy to adjust.

  • NO! Do not treat this as a Leonardo; that will cause it to stop responding. It’s (relatively) easy to get it out of that state, but it’s better not to get into it in the first place!

    As of v1.0.6, the Arduino IDE includes the LilyPad USB as an official board, so you should be able to select it in the IDE without adding any additional support files. It uses a derived version of the Caterina bootloader that the Leonardo uses, but, again, do not select “Leonardo” for programming!

  • Probably not; some of the implementation is aimed at the Atmega processor family.

  • You can skip the conversion; it’ll work fine at 3.3V. The best method is to power the Jamboree, then pull power off the FTDI header.

  • Perhaps, but unknown at this time pending future sales and engineer availability.

    I’d like to make a number of add-ons for it: a full-size protoshield (to supplement the normal Arduino one which works well with the FreeSoC2), per-port protoshields, and an SD card add-on that could connect to one of the 2x10 headers.
