Friday Product Post: GPS Sequencer Relay

Back on track after Thanksgiving with a few new products!

Favorited Favorite 0

Welcome back folks! We're back after a short break for Thanksgiving. Glad to see you all survived Black Friday! We are hard at work preparing for the holidays but we still have a couple of new products for you. Without further ado, let's check out your Friday Product Post!

A new GPS receiver and a couple of revs. Not a bad week!

GPS Receiver - GP-20U7 (56 Channel)

GPS Receiver - GP-20U7 (56 Channel)


The GP-20U7 is a compact GPS receiver with a built-in, high performance, all-in-one GPS chipset. The GP-20U7 accurately provides position, velocity, and time readings, and has high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability.

SparkFun EL Sequencer

10 Retired

The EL Sequencer is a board that contains an Arduino-compatible microcontroller, and circuitry for controlling up to eight strands of electroluminescent wire. EL wire is flexible plastic cord that glows brightly when high-voltage AC is applied to it. It's available in numerous colors (see the related products below), runs cool, and requires very little current, but can be difficult to work with because of the high-voltage requirements. The EL Sequencer can safely switch high-voltage AC on and off, allowing you to easily create animated displays or whatever else your imagination can come up with. This rev has fixed a few silkscreen errors and updated the connectors.

Relay Shield v2.0


This Relay Shield v2.0 from Evil Mad Scientist is a simple Arduino add-on that gives your Arduino the ability to control a single electromechanical relay for switching loads of up to 24VDC or 40VAC. As this is a shield, it is powered straight from the 5V power supplied by your Arduino, simply slide it into your Arduino or shield-compatible board (like the RedBoard) and you will be good to go! Version 2.0 of this shield adds the ability to control the mechanical relay from a pin other than D4.

That's all for this week folks. Be sure to check back next week for a rockin' new product! See you then!

    163 db Megawatts! Must be plutonium powered. Calling Doc Brown.

    What?...Huh?...I'm sorry, but you're going to have to speak up over the PCB in the Relay Shield v2.0.

    @Sarah great post

    mill watt or mega watt 40v DC or Ac ? ... just being picky :)

      Not picky, accurate, and with technical things those little technical details are very important. I think she should have done another take to get the corrections in.

      To the script-writer(s): even for revised products, a quick description of what the product does in the video would be good for customers who weren't familiar with the original product which is what you did. But, a quick description of what the revisions are would be good for customers who are familiar with the original product (or for us who are just curious).

      Just trying to make a good thing better.

        This is true, I didn't catch it, and I would have done another take if I had. And thank you for the info, I will be sure to include more of that info into my next script. Mostly the changes this round were to some mistakes on the silk-screen, and to the build process for our new machines. If there were more things that affected you I would have added it, this video was just saying that they are back in stock and selling again. ^_^
