well, Matrix got certified for EU region and on stock at Farnell 

 

Thanks @tinman. I'm not going to buy one... I have limited resources  BTW I see the Z-Wave chip is the old SD3502A. Of course, the other stuff on the board is cool too, but I can attach lots of sensors to my Z-Uno too... I'd say a lot depends on the code and I have not had enough time to investigate that. The fact that it has an Xilinx FPGA between the MCU and the mics, the radios, and the LEDS intrigues me. I think FPGA qualifies as "uber-geek". I toyed with them when I was in school. After all those years, my VHDL is *very* rusty . One possible application of the FPGA: add a few thousand of WS2812 LEDs and make a "nanoleaf aurora on steroids". LOL

SD3502A is not really old, is ZW500 series, used as well on ZM5202 module. The sip module ZM5101 is using same asic as in SD3502A, it is only matter of pins, saw, etc. There is different asic as well, SD3503, which is modem version of SD3502A (using special firmware, having pins hard-disabled, etc.) So basically everything "is the same", only special configs to switch pins or disable them.

 

Regards FPGA, it's not lol, it's good idea sometimes. For one of our exhibitions i did build digital wheel of fortune (yes, with z-wave module as well), with matrix LED's and so on, got lot of issues with matrix and led's scan timing. To not use FPGA i shifted colors, played with text etc. to get the best possible without not that much flickering. Next time i will use FPGA, for sure.

I stand corrected... I was looking at the spec sheet and it said: "2015" and in my brain the number looked like "ZM3102" (I know, it does not look like that). I didn't realise this *is* the latest SoC. And the ZM5101is the module that uses this SoC. I am no longer confused

Ha! That is a very nice display! I didn't mean to say "FPGA=LOL" - I meant to say "1000 times WS2812 on a MCU = LOL". The current Z-Uno library would not be able to drive that wheel of fortune, it can only handle 21 LEDs...

I've implemented a FLiRS but Z-Uno firmware 2.1.0 is not good enough yet to design a final product.

 

Z-Uno firmware 2.1.1 makes FLiRS practical, so I designed a battery operated LED light. Just for fun.

 

It is working. It did not kill my Z-Wave network

@petergebruers,

hi Peter, there should be on github a skets somewhere, but i can't find it. Pls help.

WWWWW = Who What What Where Why? I am confused, are you talking about my FLIRS sketch? You can "download as zip" from GitHub. You can also download the zip by going to:

I think that i was confused. Thnx

Have fun ("unconfusedly")

For those that want to decode RAW Z-Wave packets: ITU-T G.9959 publication (yeah... that's what the radio & link protocol is called )

Silabs released SDK and docs, for details please check @tinman's excellent summary:
