Prototype the Internet of Things (Free hardware up for grabs!)


Following our announcement that mbed.org now supports the Freescale FRDM KL25Z, I got a call from Jim Carver at Avnet, who was keen to tell me about their new Wi-Go module for the the FRDM KL25Z, which has been designed for prototyping "Internet of Things" applications.

The module has a sensor for just about everything you might want to sense :

  • 3 Axis accelerometer for 3D acceleration (MMA8451Q)
  • Magnetometer for compass direction (MAG3110)
  • Altimeter based elevation (MPL3115A2)
  • Air Pressure (MPL3115A2)
  • Temperature (MPL3115A2)
  • Ambient Light Level (TEMT6200)
  • Serial flash memory (S25FL216K)
  • Wi-Fi Communications module (LBWA1ZZVK7)

It also includes an 800mAH LiPo battery, which is capable of powering the module for a substantial length of time, and can also be recharged from USB connector. This makes it great for prototyping untethered nodes for IoT Applications.

Jim has allocated 5 of these Wi-Go modules for mbed users who want to prototype something IoT. We'll send then free of charge, to the successful applicants, and in mbed tradition all we ask in return is a cookbook page with a published, documented library, and a hello world program.

There are 8 sensors which need cookbook page + library, and 5 boards to give away, so applicants must be willing to write more than one!

If you would like to apply, please email support@mbed.org with your mbed user name, and which of the components listed below you'd like to develop for.

Of course, if you just want to buy one straight away and get started on your own IoT projects, they are also available to sale here :

There's even prizes! ...

Programs exported from the mbed online compiler in MDK format are eligible to enter the Avnet Wi-Go Design Challenge - there are some great prizes up fro grabs, with the first prize being an 11" MacBook Air

Looks like a nice module! Considering they also like to have people make motion/angle sensing applications with it I am a bit surprised they didn't include a gyroscope.

Btw from their product page I understand they deliver it with the KL25Z board, is that also the case for the modules sent to the winners?

I can see that the Wi-Go marketed by Avnet America - Is there a UK disti offering this as yet?

Indeed all the systems we provide do include a Freedom board so they are ready to go out of the box. A Gyro is great for high degree / second rotation and future revisions might include one. However I just finished porting the Freescale eCompass library to Wi-Go which combines data from the Accelerometer and Magnetometer to implement determination of roll, pitch and direction as part of a fully functional tilt compensated eCompass! We expect to have that released in the next day or so (However the eCompass code is only provided in a MDK compatible object library as source requires a NDA with Freescale.

Contact you Silica sales representitive, they may still have units in stock.

Just received my board. Re-flashed the bootloader to mbed after trying the builtin tests.

Now for some coding.

Some quick notes on port mappings to make it easier to use here http://mbed.org/users/SomeRandomBloke/notebook/avnet-wi-go-notes/

Has it been decided what parts people want to work on as a free-for-all would likely mean all the easy modules/libraries/demo code get done leaving the harder/tricky stuff not done.

Cheers

Thanks to Jim and Chris for my board, arrived in the post today.

Did a pre check of the board with code that came with it (via serial port) and all checked out ok. Just downloaded the mbed firmware and is running like a dream - well blinky LEDs!

Will work on getting code written for devices and get them posted up as and when...

Thanks again Paul (aka @monpjc)

I also started with the Wi-Go board (thanks Chris and Jim). For those developing code/libraries for this board, a (basic) CookBook page has been created with links to code for the relevant chips at http://mbed.org/cookbook/Wi-Go
These links are currently set to the Wi-Go page itself as the code is still under development.
Don't forget to modify these links as soon as your code/library is active.
