Open IoT Certification Mark – A New Certification For IoT Products

So it’s the time to witness the birth of a new certification for IoT industry. As security and data privacy in IoT platforms and products are two of the main concerns for developers and end-users, the new certificate discuss these concerns and even more. IoT is yet to have such certificate, as best of my knowledge, to pave the road to standardize the rules of openness and privacy in IoT. Although the term of IoT certification is already there, and some companies can do security test for your IoT products and certificate it, but nothing seems to analogy to certificate like open source hardware certificate, where anyone meets the principals, can use the OSH mark on his product.

The new certification IoTMark was the output of a meetup hosted on June 16th 2017 in UK. This meetup gathered over 60 participants from UK and Europe. Specifically, a 22-page-long document was the output from this meetup. This document contains the principles of the certificate:

  • Privacy
  • Interoperability
  • Ownership, Permissions, Entitlement
  • Cost/biz models/pricing transparency
  • Security
  • Lifecycle, provenance, sustainability & future-proofing

To mention a few of these principles:

Privacy


The supplier of this product or service MUST be General Data Protection Regulation (GDPR) compliant.

This product SHALL NOT disclose data to third parties without my knowledge.

I SHOULD get full access to all the data collected about me.

….

Interoperability

  1. Have an open platform API [MUST]
  2. Provide comprehensive platform API documentation [MUST]

The preparation for the certificate didn’t finish yet, where The folks behind this certification will finalize it and register the mark by December 2017.

Don’t forget to have a look at the full document here. Who knows; You could use it in your next product. It’s really worth to give it a bid!

STM32 Arduino compatible board

@ instructables.com build an alternative board to Arduino using STM 32 series of mcus.

We love the Arduino board and it’s prototyping platform . It makes the complete prototyping process smooth and enjoying with the help of it’s add on such as Arduino IDE and a huge community support.But sooner or later you will find that the specifications provided by the arduino boards is not enough . And then the problem arises about which board should we use so that our desires are fulfilled.Also How easy is to use a non arduino board . After a good research I found that the STM 32 is perfect fit.

Sonnet Off-Grid Device, The Smartphone Walkie-Talkie

At Sonnet Labs, a group of avid outdoor enthusiasts aim to democratize mobile communication with technologies that enable smartphones to send text messages, image data, and GPS locations without Internet connectivity, cellular coverage, or satellite reception.

No need for cellular grid with Sonnet

Therefore, they launched their product, Sonnet, the smartphone walkie-talkie! Sonnet is a wireless device that brings the long-range wireless communication capability of the 2-way radio (walkie-talkie) to smartphones. In addition, it enables device-to-device data transfer through low-power, long-range radio frequencies dependently on cellular grids and infrastructures.

Accordingly, Sonnet can connect wirelessly to any smartphone. Also, it allows sending data up to many miles in distance to other smartphones that already are using Sonnet.

More features to come…

Sonnet uses mesh networking in order to reach users out-of-point relaying on sending data privately through other users in area. This data travelling through Sonnet is already end-to-end encrypted with AES. At the same time, the Sonnet Wi-Fi connection is protected with WPA/WPA2.

It also has the ability to charge your phone. Thanks to the 4000mAh battery capacity, Sonnet can charge your smartphone through its USB port.

Moreover, you don’t need to install software in your smartphone. It is enough to have an access to the app through your browser. The team tailored this feature to allow users who don’t have internet access to use the device easily.

Above all, one of the amazing features included is SOS mode. In case of emergencies. you can press the panic button. Next, Sonnet will send your GPS location and your message to all users in range.

Full specifications of Sonnet below:

In conclusion, Sonnet is the wireless device that enables you send instant messages, voice recordings, image data and GPS coordinates even if you don’t have cellular coverage or Internet access.

Sonnet is now live on a Kickstarter campaign and has already achieved 290% of its required funds. The campaign still has 28 days to go, where you can pre-order two pair of Sonnet for $89! Also check the official website for more details.

2-3A, 42-Vin Silent Switcher offers low-EMI regulation

LT8609S is a 2A (3A Peak), 42V input synchronous step-down switching regulator. The synchronous step-down Silent Switcher 2 Delivers 93% efficiency at 2 MHz with ultralow EMI/EMC emissions. By Graham Prophet @ eedesignnewseurope.com:
The LT8609S design reduces EMI/EMC emissions due to very well controlled switching edges, its internal construction with an integral ground plane and the use of copper pillars in lieu of bond wires. This improved EMI/EMC performance is not sensitive to board layout, simplifying design and reducing risk even when using two-layer PC boards.
