Murata CMWX1ZZABZ chip is actually famous for being a powerful LoRaWan multi zone module also able to communicate over Sigfox.
I’ve already published a technical post on Murata CMWX1ZZAB chip in a previous post. You will also find an implementation based on my IoT SDK. Yadom has just released a breakout board ( BRKABZ01) for this chip making it accessible for hackers and for easier prototyping.
This post is going to review this board and demo how to access it really quickly. Are you ready ?
Basically SNOC SFM10R1 aka BRKWS01 Sigfox devkit is an easy way to get start on low cost sigfox hardware thanks to the low cost module from wisol based on the low cost chip from On Semi Ax8052. Presented like this it looks like stack on a stack on a stack.
But in my point of view the solution is really more than this. As a maker I know how difficult it is to kickstart a Sigfox project : you have to deal with expensive devkit where you sometime need a Kbis, then you have to deal with sigfox to get an access and at ends if you want to transform you POC in a product you need to change you technologies for cheaper or simper solutions. (here I’m not pointing anyone but basically I had to made my own devkit to start on sigfox) Most of these problems have already been solved thanks to sigfox making account creation so simple for devkit and the arrival of devkit like snootlab, airboard or smart-everything. All these solutions are nice but provides a full stack solution MCU + communication for a price around $100. This is where the SNOC module is proposing an alternative : get an easy access to the sigfox network with a low cost solution you can plug to the MCU of your choice… Arduino, Rpi, Nucleo, Pic it’s up to you !
In a previous post I explained why the IoT is appearing in this period thanks to the network technology evolution. It would not be a complete analysis if I would not care about the social evolution. In parallel of IoT and technologies there are other rising trends : Makers, Fablabs, embedded systems,3d printing and crowd-founding.
Take a look at personal computing some decades ago when guys like Jobs or Gates make the first line of code and solder the first micro-processors in their garage ; they just used the technological elements available that time and were able to make them doing much more than what they have been made for. They did it because they were able to do it. The same story appends in the late 90’s with Internet : anyone was able to code some PHP stuff and create a service in his garage thanks to this students have created Facebook and many more.
At the opposite, when smart phone appeared in the middle of the 90’s it was a technology that requires strong industrial assets and this technology has been limited to major companies. The smart-phone revolution had been the same opening door to programmer to an new area with applications (apps). In fact all previous hardware evolutions since the Personal Computer beginning was requiring huge technological assets to be part of it.
IoT disruption is breaking these last 40 years where only software were hackable by getting hardware accessible.
