It’s a keychain? It’s a development platform? It’s mBuino!

We are excited to share the Kickstarter launch of GHI Electronic's new mbed-enabled platform, mBuino. mBuino is a programmable mbed-enabled keychain that features an ARM® Cortex™-M0 50Mhz, UART, SPI, and I2C.

Don’t let the pint-sized design fool you, this little board can do so much more than make your keys look cool. To start you can easily make the on-board LEDs blink or you could get a bit more creative and create your own video game platform (joystick, color display and all)…check out the example they show in their Kickstarter video. It is even programmable with mbed. By simply connecting the mBuino to your computer, and using the mbed online compiler, you are able to easily write code and save your code to the device.


This little ingenious idea came about as a ‘round table’ project from the engineers at GHI Electronics, LLC. They wanted to create something that reflects their passion for electronics…which I have to say, I think they have achieved! The profits from this Kickstarter will go to help funding their ‘OutrageousCircuits.com’ website which will allow this creative group of engineers a place to share more of their outrageous designs and products. This is just the beginning of their work on creating mbed development platforms and we are excited to see what they come up with next!

Help fund this project, here!

The ARM, Avnet, and Freescale IoT World Hackathon Challenge

ARM, Avnet and Freescale are hosting a Hackathon at the IoT World Event next week (June 17-18) in Palo Alto, California at the Crowne Plaza Hotel. Our hackathon challenge is to build on from the other IoT World Hackathon Challenges that should produce some compelling consumer and environmental IoT innovations. We want our hackathon participants to think outside the box and create projects which are interoperable with other teams; where at least part of your application works with part of an application from one (or more) of the other teams.

If you are interested in participating in this event, register here. To find out more about ARM at the IoT World event, check it out here.


What to Expect:

ARM, Avnet, and Freescale are sponsoring the hardware, software, and technical assistance for our hackathon. A number of WiFi enabled Wi-Go Microcontroller + sensor platforms will be provided by Avnet. The ARM® mbed™ web IDE for embedded devices will be provided for drag-and-drop software module composition and programming of the Wi-Go modules, using mbed sensor and communication libraries.

The ARM Sensinode™ platform connects the devices to web applications using CoAP and OMA LWM2M IoT standard protocols. Standard protocols and web objects enable interoperability between sensor devices and web applications through the ARM Sensinode platform.

An example demo application will be provided to enable participants to start off with an end-to-end connection and a hackable sample application. ARM will provide technical assistance to help participants use the Wi-Go system, mbed, and the ARM Sensinode Platform. The interoperability challenge is for building applications that work with applications from other teams.

Hardware Provided by Avnet:

Avnet Wi-Go System, 7 sensors, Battery powered, WiFi

Freescale Kinetis KL25Z MCU, ARM Cortex-M0+

Software from ARM:

ARM mbed open source web IDE for embedded devices

ARM Sensinode platform connecting devices to cloud and web applications

CoAP and OMA LWM2M standard API

Hope to see you all there!

Time to Get Creative with the Freescale FRDM Boards

Digi-Key, Freescale and ARM are hosting a European design contest to inspire developers to get creative with Freescale's FRDM development boards. If you have not already started developing with one of the FRDM boards, now is a great time to start. There are over ten boards to choose from within the FRDM family, but we would suggest using the FRDM-K64F, FRDM-KL05, FRDM-KL25Z, or the FRDM-KL46Z.


The first phase of the competition is a ‘Conceptual Design’ challenge, where you will need to design in block diagram format a feature set extension to implement your design. You will need to create your design on Digi-Key’s ‘Scheme-It’ to enter. Phase one submissions will be accepted through June 30, 2014. The winners will have a chance to win the following prizes:

  • 1st place winner will receive an Apple iPad Air
  • 2nd place an Apple iPad mini
  • 3 honorable mentions will an Apple iPad touch


The second phase of the completion is the ‘Hardware and Software Design’ challenge, open from July 1 through October 10, 2014.Using PCB-it and mbed.org take your design bring it to life. It is not necessary to be a winner in phase one to be eligible to participate in phase two of the competition. Below are the prizes for

  • 1st place prize for Best Hardware and Software submission is a Football Table valued at no more than (€1,500).
  • 2nd place prize is a Jura Type Espresso Machine values at no more (€1,000)
  • Honorable mention prize will be a bicycle valued at no more than (€750)

Now it’s time to get creative, check out the official contest page here.

Win a Samsung Galaxy Note III and Polar V800 sports watch

STMicroelectronics are offering a Samsung Galaxy Note III smart phone coupled with the Polar V800 sports watch to the three winners of their Internet-of-Things design challenge this year.


To enter the competition just pick up your preferred STM32 based development board and add at least one other ST component then send a description and video of your innovative application (full T&Cs can be found here). Should you be one of the 3 lucky winners you will receive an invite to the award ceremony during Electronica in Munich – November 11th – 14th 2014.

If you would like to get something up and running quickly, easily and with a whole community backing you why not choose one of the many ARM® mbed®-enabled development boards: the ST Nucleo boards based on STM32, available for only $10. The mbed.org website lists 5 different boards that are instantly available (F103RB, F302R8, L512RE, F401RE, F030R8).

Not a bad return on investment; a cutting edge smart phone and watch worth $1,200 for a $10 development board and a bit of fun engineering. Alternatively, if you register your idea through the Facebook page before 31st July ST are providing FREE Nucelo boards and Wurth Elektronik are giving away free passive components for the project.

Good Luck!

Note, the Galaxy Note and Polar V800 replace the previously announced Hyetis smart watch.

mbed at Bay Area Maker Faire, The Greatest Show (and Tell) on Earth

See a selection of ARM® mbed™ projects and development boards at the Bay Area Maker Faire this weekend (May 17th and 18th). Come and visit Booth #405.


Ask Calum, Systems Engineer at Xively how the industrial tank filling system makes use of Google glass and mbed /media/uploads/Phill_/xively.jpg

Ask the team about the JKSoft wallbot and what’s next


See how easy it is to create appcessories using the latest mbed platforms alongside other popular development systems.


IfixIt will be on stage tearing down a selection of wearable appcessories to show us what chips and components engineers are choosing for commercial products. One of each of the products will be available to a member of the audience at the end of each teardown. /media/uploads/Phill_/featureddemotimes.jpg

More details about the show (and tell) can be found on our connected community page.

We are also running a raffle for free tickets, check out the details on our facebookpage
