NRF24L01+ mini VS normal size module ?

[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.

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.

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).

@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 :)
