💬 Easy/Newbie PCB for MySensors

[Efflon]

@mfalkvidd I ordered January 2 and can't remember what version was stated. I'm quite sure I picked Itead because it had a higher version numer (and a slightly higher price), honestly don't remember. All I know is that I didn't read this thread but rather just browsed through the page and clicked order. Afterwards I realized it wasn't clear if it was the 5V or 3.3V version but the order said 5x5cm. I also missed to choose color but "grönt är skönt".
Guess what confused me most was the statement "It may say another rev. at the orderpage but this is not EasyPCB rev but the rev for manufacturer." causing me to be trigger happy :smile:

@Efflon - sorry to hear you got rev 8 if you wanted rev 9.
I wrote this notice just because itead was so slow updating to the right revision! I also spoke to hek about this a month ago according to my chat log.

Sorry to hear... Checked the log. The order was for manufacturer revision 4 (which is what @sundberg84 call rev 8 ).

The system automatically increments the revision number each time an author makes a new release. Each manufacturer must set price on each revision(which in some cases may take a while if they do this manually). Until they've done that, any older revision where they've set a price is still available for purchase.

The revision is stated below the big order-button.

Could anyone explain me, why position (polarity) of condensers 4.7uF on REV 8(blue) and REV 9 (red) are different?

It's a bug in v8 fixed in v9, so v9 is correct, see link this post

@SUNDBERG84 - Do you have a board/design for the RFM69 radio ?

Rergards,
Martin

[ferro]

@martins - you can use NRF2RFM69 if you want to use RFM69 with Newbie PCB board. I'm using it too, works fine with 3.3V arduino. For 5V arduino you will need to add level logic converter too.

@ferro
Pity because that would double the cost of the sensor board:

Order PCBs for Easy/Newbie PCB for MySensors : $15
Order PCBs for NRF2RFM69 : $15

Thanks,
Martin

Thx for answer :-).

[sundberg84]

@martins - No, not at the moment. It has been asked before but I have never got my head around it.
As i told before, you are happy to develop it yourself. I have some other things in my list but in the future maybe :)

Hi
I've tried to order the capaciter and voltage regulator from our local electronics supplier. The choice is too big. Could anyone please help a "newbie" to select the right parts for a raw powered 5V version

• 4.7uF capacitor
• voltage regulator
• 0.1 and 10uF cap
  http://www.distrelec.ch/ can't select the parts because of missing size and especially for the voltage regulator the exact type.

[sundberg84]

@N00phi - I usually just select the ones at www.mysensors.org/store but if you have a specific site you wish to order from I can choose for you.

[N00phi]

@sundberg84 It would be absolutely great if you could do so! I would order at http://www.distrelec.ch ...

[sundberg84]

@N00phi for the capacitors: http://www.distrelec.ch/search?q=electrolytic+capacitor&filter_Rated+voltage~~VDC=50&filter_Diameter+housing~~mm=4&filter_Diameter+housing~~mm=5 (choose the axial types which is the one with two legs).

As for the voltage regulator I use LE33ACZ 5V-3.3V which i cant find on that site.

Just for clarification, there is axial lead and radial lead components. The axial leads have both wires coming out of one side (as @sundberg84 mentions it looks like two legs). Radial leads have one wire coming out each side. I almost never use radial lead capacitors.

@sundberg84 Thank you! One more question.. on the photo, there is a flat broun capacitor, what are the specifications for that one? Is it 0,1uF? But thats not an aluminium electrolytic capacitor, is it?
Oh, and the voltage regulator is available on aliexpress, found that one.

Yes it's the 0.1uF capacitor. It's a ceramic disc capacitor, but you won't have to search for the type of capacitor on aliexpress, low value capacitors are most of the time (always ?) ceramic disks if they are not of SMD type.

I would like to use this PCB with a 3.3V I2C sensor (data line and power must be <3.6V) and AC power. Is there a recommended way to accomplish this?
