Not really an external power source, you can just use the 5V output from the arduino and use a voltage regulator to 3.3v.
I bought some of these http://www.gearbest.com/transmitters-receivers-module/pp_453011.html and I am very happy as they allow for quick swap of the radio and already have capsDear gohan!
Thank you for your help. I will buy from ebay this one: https://www.ebay.com/itm/200960749614
And im planning that i will buy a shielded nrf24 pa+lna .
Today im installing an openhab and try to transfer the datas from gateway to the openhab...What projects have you done already?
Best regards

I probably missed that because I never seen the caps being specified
If they work, good find
On ebay, i cant find the bypass capacitor in the specs. I have written to a seller asked about it. I will report to you about the answer.
I have tried once again the two high power nrf24 pa+lna (I put foil onto these) but these dont work. I think these are broken or very very bad ones.
Could you suggest to me a seller who sells High power nrf24 which ones you have got good experinces?
Thanks,

Hi rejoe2!
What kind of nrf24 do you use, and where did you buy these?
I think that you use capacitor as well, and stable 3.3V dont you?
Do you think that this shield is good for my node? It would be very good if i didnt have to use cables for nrf24....

I use nRF-Modules in the "normal" format and several pa+nla-Variants,. The first ones I probably bought from the ebay source mentionned on the mysensors-site (build-page), but by now, I may have used parts from around 4-5 different ebay-sellers as source. They look different, but until now, I only got "non-blob"-modules which all seemed to work reliably in the end. One time, I really was convinced to have bought fake and bad ones, but in the end it turned out these problems where mainly sw-related.For powering, I initially used AMS1117-only-Modules and additional caps, but using the above adaptor-modules made things much easier, as they have all relevant parts on-board (3.3V+caps, space is no problem in my personal use-cases).
Fyi: As I now prefer wires over rf, I'm about to replace most of my nodes by RS485-variants.

Thanks for the suggestions.
Had you got problems with nrf24?
Tomorrow i will try to configure openhab. I have tried to find a quick up to date guide for openhab 2 + mqtt mysensors but font find one.
Mysensors said that their bindigs support only ethernet or serial gateway officially.
I dont understand what is the diff (or why mqtt used mostly) the ethernet and mqtt solution but i have started the mqtt already.Best regards

I indeed had some troubles with nRF nodes, but related to this.
FHEM is used as a controller and two serial GW's, so: no experience with the MQTT stuff.I see. I hope, i can use it for a while:).
I think im closed this topic. The solution was to change the nrf24 modules, because i could not pair them.
The anoother problem was that i use two power source, and i didnt common the GND.Thank you everyone who helped to me!

Reading through your posts: am I right in assuming that these NRF24L01 are rubbish and I should buy some proper ones with a chip instead of a blob?
Or has anybody a pair of them up and running?
Thanks and best regards,
JoachimI havent had got blob one yet so i havent got experience with it. But i red about the blob version and it should work....
But I suggest to you that you should buy these from reliable brand/shop. I think Itead or keyestudio are reliable brands. And i bought a pair nrf24 from ebyte, but it hasnt arrived yet. -
Ok, spent half the day trying to figure out what I was doing wrong and all I had to do was read the forum. The radios I purchase were junk. Not one of the 10 worked. Had everything placed on a board figured my workmanship was a little off or something. The radio was last to be checked.
WOOOOOOWWWWOThanks Everyone this post saved me a lot more time.
