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 !
