How do i know it;s a polarized version ?
There are these ( which i think are the wrong ones )

Thanks, i found everything on Aliexpress, except:
Push Button SPDT
Resistor 1M ( which package size )Alex
@Slorf
Resistor 1M ( which package size ) - unnecessary element (R1 can be mounted for backward compatibility with nRF24L01, nevermind)
Push Button - use any buttons like these http://ru.aliexpress.com/item/10-Pcs-x-Sealed-SMD-Momentary-Tact-Tactile-Push-Button-Switch-3mm-x-6mm-x-2/32600602500.html?spm=2114.30010708.3.10.QkNxnX&ws_ab_test=searchweb201556_6,searchweb201644_3_505_506_503_504_301_10020_502_10001_10002_10017_10010_10005_10006_10011_10003_10021_10004_10022_10009_10007_10008_10018_10019,searchweb201560_3,searchweb1451318400_-1,searchweb1451318411_6451&btsid=efafd213-4a02-41ac-8d40-b5e9982a58f1 :wink: -
Hi,
When I try and order the pcb's from dirtypcb I get the following error:
PCB #17568: No board outline (.GML/.GKO/.GBR) file found.
I made a zip file with cam.drl, main.gbl, main.gbo, main.gbs, main.gtl, main.gto, main.gts
when I try to upload this on dirtypcb I get the error message that there is no board outline.regards

@Slorf It's openhardware.io engine problem. Engine had removed some files from my zip. Use files from this complete archive (gm2 - mechanical layer, rename it if its nessesary).
0_1456686721977_nrf_17_01_fabr.zip -
.gm2 was a new extension I didn't know about.
I've updated the file extraction engine. When you get a chance, please try uploading it again. -
I renamed the gm2 file to gml ( see: http://jrainimo.com/build/?p=642 ), and was able to order it from dirtypcb.

I mailed the people at dirtypcb, hopefully they can change it for me.
If they cannot change it, would it be possible to get rid of the antenna and mount a pa/lna antenna ?
Regards
Alex
@Slorf Do not worry. Antenna will work with any board thikness, but with 1.6mm (with current geomerty configuration) it will be optimal. Almost all china nrf modules (I've seen) have non optimal antenna geometry.
PS
I'am sorry :( I hope dirtypcb will change you order.@Slorf said in MySensors Stable Node:

It is possible, but its very non technologically...
-
Great board.
Did you test the performance ? Like number of recieved packets per second ? -
Let's hope the change it :-)
Would it be possible to mount something like this on the pcb ?
-
Couple of questions :-)
How to mount the second Quartz crystal ?, there are no holes in the pcb
The LDO regulators are mounted next to 4.7uf capacitors, is it correct that the regulators and capacitors are connected to eachother on both sides ?
On the photo of the assembled pcb it looks like this, but on the photo of the plain pcb and the schematic it look different.
| Pin 1 IC3 Pin2 | | Pin 3 Are pin 2 and 3 also connected to the capacitor left and right pin ? Left pin | C14 | Right pinThanks !!

@Slorf
Q1? Q1 is smd quartz. Q2 can be smd too but it can be difficult to mount it (so I've placed holes).I do not understand about LDO. You can check pinout in datasheet http://www.torexsemi.com/products/voltage_regulators/data/XC6206.pdf . May be datasheet schematic model (picture) is different from my library schematic model. But schematic and layout are correct.
-
Hi, the bom says 2 x quartz crystal
I did not know they where different and one should be smd.
Could you tell me which quartz crystals I should get ?
Will check out the datasheet for the LDO :-)
Thanks
Alex
@Slorf I've left the package field in bom blank, so you can use any crystal you have. All components on the board are smd, so crystal should be smd too if you have it. But it may be difficult to place smd crystal as Q2 (too small area) and I've placed holes. I have both SMD and THD crystals but I will put holes in Q1 crystal pads in the next version too. Now you can simply mount THD crystal on the pads, it's not difficult.

It's possible. But I want this board to be as compact as possible.

Did you test the performance ? Like number of recieved packets per second ?Thanks. I've tested stability (for some months without troubles in typical applications) and RF range. I think it doesn't make sense to test performance with low performance mcu, but you can propose the sketch and I test with it.

I have both versions ( SMD and THD ) crystals on order with aliexpress now :-)
As for the LDO regulators, I will wait for the PCB's to arrive before making assumptions ;-)
Now I have to wait some weeks before everything arrives ........and then my first smd soldering experience !
