Talk² on Kickstarter

As you may already noticed, we’re running a Kickstarter campaign. The objective is to get enough pledges to produce our Whisper Node in larger scale, reducing the total board costs to everyone.

Thank you all for supporting us! The project got funded and all updates will be posted directly into the Kickstarter Campaign page: https://www.kickstarter.com/projects/340271897/whisper-node

Low Power Budget

One of the biggest challenge for the Internet of Things, especially for those devices using RF communication, is the power consumption. In many situations it’s normal to expect the wireless equipment to have their own source of power, instead of relying on an AC-DC power supply connected to the wall outlet. In the IoT world there is a real demand for 100% wireless devices, powered by battery or any kind of power harvesting.

The first question you need to answer yourself before start building battery powered circuits is: For how long I wish the device to run on new batteries? One day, a whole week, maybe a year? Or just be brave and say 2 decades.

On this post we’ll talk about the low power world, how you can plan, design and implement circuits that can work for years on a pair of wide available AA batteries. We’ll also present the common trade-off and techniques necessary to reduce power consumption, as well discuss how RF communication can be implemented with minimal power requirements.

This can be a very complex and long topic and we’ll try to keep it as much practical and simple as possible. Bear in mind that we won’t offer a ready-to-use, kind of copy and paste code. The whole idea is to be broader and educate how to identify and solve common problems.

Meet Talk²

Talk2_Transparent

Say hello to Talk², or Talk-Two or Talk-Square!

Today is our first post and we’ll explain a bit about this project. Before starting, feel free to follow us and leave you comments or suggestion. We’ll try to keep all details about this project as much up-to-date as we can, as well reply to any question you might have.

First come first: What is Talk² ?

In a sentence: Talk² is a microcontroller development solution with build-in communication capabilities. But in reality it takes a bit more than that to explain all the features and the problems it tries to solve.

You may noticed, we used the term development solution instead of development board, that’s because Talk² is designed to be a platform independent solution. In the real life it means that you’ll be able to make your Arduino project talk with a Raspberry Pi using wire or wireless communication. Better than that, you can reliably send and receive messages to your MCU from the Internet, which can be an AVR or ARM.
