@ahmedadelhosni If you have some spare time, very interesting readings:

@YveauxThanks.

I have already read some of the posts today :) That's why I knew the blob issue.

So is this supplier which is on the store trusted :)

Not a clue. According to Nordic, only official distributors can be trusted, but they'll charge you $20 + for a single module...
No wonder we all buy our stuff from China.

[ahmedadelhosni]

@Yveaux oh my GOD !! $20+ !
I searched on digikey and the highest price was 6~7 dollars and I thought this is expensive.
So I thought it is original https://www.digikey.com/product-detail/en/113990021/1597-1226-ND/5487768

You have a link to official distributors as I couldn't find on nordic website ?
Thanks.

[ahmedadelhosni]

I also found it on sparkfun. 20$ ! According to you, this is original and the one from digikey is high copy for exmaple :) ?

Interesting find. Didn't know Digikey was reselling Seeed studio units!
Beware that this Seeed module is an amplified version, with regular antenna. That's quite a unique species :alien:

When visiting the Nordis Semi website on the bottom right you can search the nearest distributor. For me e.g. Mouser is reported, which sells these modules at E 35,21 a piece!
I can buy roughly 50 boards from China, for the same price.

I cannot tell if the ones from Digikey are genuine, or from Spartkfun; even Nordic has to put them through X-Ray to be absolutely sure.

@Yveaux
No wonder they are no longer in stock according to digikey :)

Thanks for the links. Actually I have searched earlier for the NRF in mouser but couldn't recognize it as there was no picture in the search result + I didn't imagine it will be 38$ :) http://www2.mouser.com/Search/Refine.aspx?Keyword=nrf24l01p

Thanks for your help.

@Yveaux

mouser also sells seedstudio nrf24's (the amplified version).

if you want to buy the (genuine) chip only, it costs 1.56 at quantities of 4000.. (mouser prices).

[ahmedadelhosni]

@tbowmo Will it work Ok if I get a clone board but replaced the chip with the genuine one ? :) I mean does the genuine pcb differs also ?

[Yveaux]

@ahmedadelhosni yes it will (I did it myself) as long as you don't buy the blob ones :blush:

[ahmedadelhosni]

@Yveaux Great. That's really amazaing :)

Sorry for lots of questions. But did you monitor any great differences between both chips ? or is it life time ? or what ?

[Yveaux]

@ahmedadelhosni I still have to discover a clear difference between clones and genuine chips. Power consumption seems different, but not clearly... That's what one of the discussions is about: how can we tell the difference.
Nordic might know, but until now they didn't want to share with us.

[ahmedadelhosni]

@Yveaux Yes I have checked the nordic website regarding the power consumption and they are nearly the same in deep sleep.

Anyway, thanks a lot for the discussion :)
