Apart from the plain impracticality of doing it at all, I don't know how you'd manage the impedance control for the antenna connection.

Flexi PCB design is a specialist area, and doing it for RF would be a specialisation within that.

Yes, I was thinking of people doing chip-level design rather than modules. But there's no particular reason why you shouldn't put a module on a flex PCB.

I have worked with a company which was doing such a thing.

But not come across a flexi module.

Yet ...

I'm not aware of any modules with flexi PCB, pretty sure it doesn't exist. You either have to use a commercially available module or you have to design it yourself.

Thank you awneil!

That would seem to settle the matter at a practical level (I'm curious whether anyone has seriously attempted this or if there's a very good reason not to try?).

Follow up question r.e. a flexi-PCB (seemingly the best solution here), where are the best places to design and purchase a flexi-PCB compatible with an nRF52 chip? And in the context of a prototype/ proof of concept (so just a few dozen PCBs initially)?

Are there any generic flexi-PCBs appropriate to use in a case such as this (only real requirement: breaking out GPIO pins).

No.

But, surely, if you have space for a battery - it could go on a PCB there?

Some people are using flexi PCBs in such applications...
