💬 Easy/Newbie PCB for MySensors
-
I'am now finnish with my first rev7 node.
It is a Arduino 5V with DHT-22 and a HC-SR501 sensor.


Good work @sundberg84 for the PCB
-
@BastienVH Good to hear - its not essential to have to 0.1uF cap on the voltage retulator, it will work without but its good to keep noice out.
@ErrK Nice, I see you run through RAW pin and using the internal voltage regulator on the arduino - I have not tested that much, does it work ok? -

When I get the caps, I'll place them on the board.
I did notice alot of noise when I was reading battery state on a breadboard in an earlier build, so I will get that sorted.
Only problem is I can't find them locally, so have to get them from China.
Will take a while... -

It was up for only 15days.I will now test with a arduino that i have removed the led and volt regulator.

Sounds good @ErrK - dont forget to power it through REG and not RAW on the PCB and add a jumper on REG since it wont work if you use the same setup as in the images and remove voltage regulator.

Thank you @sundberg84. I will think of that.

@Barna - I just wanted to make it smaller, with the radio not sticking out so much.
I ordered them a while ago, so if they made it out of china before their new year I think it will be tested soon. -
Nice. @dark-nico
The main concern is the new placement of caps and voltage divider - I hope they fit in between the radio and screw terminal. Should not be a problem - but you know, always nice to see it IRL. Might be good to solder them first before radio, arduino and screw terminal. -
Ok, I'll do that.
My main problem is that I haven't received both my booster and my 5->3.3 reg. :disappointed:
So I can test Batt version by bypassing the booster, but it will not tell us if the reg placement is ok.
I'll dig in my "donor harware" if I can find a reg. -
@dark-nico - You know its easy to cut the PCB to make it smaller? Using it as 5v you can remove the right battery part:
Either cut with a knife and brake:

@sundberg84 - Yes I know that I can cut that part, but I think this one will be my test board with all this option, including the battery parts.
However I'll keep the video method in mind, I was thinking about using a dremel, but, it seems cleaner. -
@dark-nico Ok, have not tested adding both Bat and reg/5v posibilities at the same time. Might be that 5v travels backwards towards the booster... try it out, but as I said, not tested.
-
@sundberg84 : I have also received the rev 7 from DirtyPCB and learned how to solder. Very nice and flexible design !

Perfect for a Newbie :). Thnaks a lot for sharing -
Hi!
No problems! Makes me glad to see i made something usefull for others :)
Interesting setup you got the with the HLK as power :+1: -

@dakipro If you "download all project files" @ https://www.openhardware.io/you will get all files (Eagles, Gerber (run with Iteads CAM job) and other stuff).

Please excuse the questions, but you did say this is for Newbies, right? :)
I'm planning on using this with the 3.3v Arduino with battery power once things are debugged. I see above that you say to power from the battery input rather than the FTDI pins. Is that for 5V and 3.3V? Also, what is the resistor labeled D3 Res Temp/Hum used for?
