MCU Radio Modules available for sale. if anyone needs it for their projects, this is great working design. Can be used with Sparkfun's library with small modifications or without any library, I can provide sample sketches and plenty of help. Boards already been bought and tested by other people thru this forum. It's $30 via paypal or $35 thru ebay, standard shipping in USA is $3.
Send me private message and I will respond. All boards made and shipped from USA Michigan.
Thank you.
Alex.
I can't find it on Ebay.
It is okay if you post a (commercial) link to your Ebay item, after puttting so many work in it.
Hi, Krodal. Sorry but I run out of them already. I need order some parts to assemble more of them. You are 100% right about the link to the item, and I will post it, as soon as I put some more on ebay.
Hello all!
We've made a bit of progress on our radio project I posted about last year and currently have our hardware and software files for our second revision on github here -> the public radio · GitHub, for anyone who's interested. Occasional updates are also being made here -> http://yourpublicradio.tumblr.com/ where you can learn more about what we're building. We're still trying to improve our FM reception though, and would appreciate any feedback anyone might have with regards to the board layout and antenna design.
Cheers!
Alex are you still making the boards either populated or not? Would love to get one.
If the supply voltage for the Si4735 is too low, it could be provided by Arduino D8 + diode + diode + a transistor like BC547 with basis to the 2nd diode, collector to +5V and emitter to Si4735 p21 (VDD).
That should provide ~3.2 V with sufficient current.
Alternatively, on the 4050, p14 (6A) could be connected to p3 (1A), and p15 (6Y) could be connected to p2 (1Y). The supply for the Si4735 would then be shared over 2 4050 output ports in parallel, each providing half of the current.
anyone selling or got a source for blank pcbs for 4735 ? Or populated ones? /thanks!
