Hi,
Please let me know which of the parts you can not find, and I will try to find another sorce.

Hi, thank you very much for the reply.
I am having only one good source and that is www.element14.com
The BOM item names are not available on element14 when searched.
What alternative can be used?
-Siddharth
Unfortunately not all parts can be sourced from element14. Don't you have access to aliexpress?
aliexpress has been banned in my country.... :-(
are there alternatives to the components in BOM?
I'm sorry about that, unfortunately I am not aware of any alternatives
Hi, there must be an alternative, RS, Mouser, Farnell, Digi, ... https://lcsc.com
the big question is if they have the cc2500 modules. I doubt that.
how about Digi-Key ?? they are available here.
Hi, Most parts can be found on digikey (albeit a bit expensive) but the most important part is the cc2500 module and can not be found there. Question: can you buy things from ebay? https://www.ebay.com/itm/381876823225?hash=item58e9a1e4b9:g:xS0AAOSw4GVYR392

Ebay closed down shop in India almost 6+ years ago... It's difficult to make anything in this country at times... :-) but I will surely make it.
Also regarding the BOM I have one query. When you mention C2 value as 22u_0603 does it mean 22uF capacitor ?
dns_0603 (C4) is not understandable... and 22u_0603 is not being replaced by 22nF in the search!
now I am looking at the following sourcing options:

This is available!

Yes.
This is available!
It is compatible, but you will need to modify the pcb to use it (or connect the module with wires) also, it has a built-in antenna, so the range might be shorter.

I also have doubts about the internal RF antenna... so I am trying to see if I can get the 2500 PA module.
can you please clear the doubt about the C4 which says dns_0603 as it is not showing any results on searching!
1. this module have also internal antenna but it is compatible with the pcb: https://www.robomart.com/2.4-ghz-rf-transceiver-cc2500?search=cc2500&dsearch=cc2500 2. C4 dns, means Do Not Solder (it is there for tests, but you dont need it)
Thank you very much for both the answers! Appreciate it!!! :-)
I will try to see other component sourcing from Digikey or Evelta as they are the only 2 options left with me now. :+1:
hi... still stuck with component sourcing unfortunately! :-(
UPDATE looks like it's taking time to source but getting them.
some are not not showing the component for e.g.
CSTE16M looks like a resonator SMD but unable to find one! can you guide me to one please.
Hi, The link of the Q_NMOS_GSD mosfet no longer works, could you tell me if this https://ar.mouser.com/datasheet/2/268/20002092G-1218133.pdf is the same?

It should be at lease 5A mosfet such as AO3416: https://www.aliexpress.com/item/1005003648743765.html
Thanks for the help and for sharing your project is great.
Hi, What is the secret for the crystal to work without capacitors? The selected crystal?
It is not a crystal at all, it is a ceramic resonator. It does not require capacitors.
Hello,
I am planning to make FR-8 as per your instructions but I am finding it difficult to source the components as per your list in Bill of Material.
What alternative do I have to carry out this work?
