So how would someone go about purchasing this ? Would it require custom ordering the PCB ? Seems like a very cool way to make affordable cheap USB microphones.

Yes, you’d need to do exactly that. The PCBs can be ordered dirt cheap at Chinese shops like JCPCB. They are associated with LCSC, a cheap component supplier of Digikey, that also provides the RP2040 microcontroller (though currently out of stock, as expected with today’s supply chain.) They even provide cheap PCB assembly services.

  JCPCB is not a PCB shop. They get the order, and then run to an actual PCB shop of their choosing.

    1) It's JLCPCB, not JCPCB: http://jlcpcb.com/ http://jlcpcb.com/ 2) What is the source of this information? (honest question)

        Got it, thanks. Btw, have you followed their SMT Assembly service offering? I've assembled 40+ designs with them this year, and it does seem like they do it on their own instead of delegating. Nobody comes close to their prices and assembly time.

        If you give any SMT house JLCPCB's volume, they will do everything for you, sameday service included

        The magic of JLCPCB is that they can do SMT mounting quickly, cheaply and for as low as 3-5 boards. My standard iteration time is about 8 days (which includes shipping from Shenzhen to SF Bay Area) and it liberates me from a need running an assembly shop locally and I can spend more time on what matters. Traditional SMT houses usually have very rigid and expensive processes on setting up their Pick&Place machines, so giving them JLCPCB heterogeneous volume would not necessarily yield their interest.

    Does it matter who they subcontract it to? At the end of the day, you as a customer only interact with them. It’s like pedantically correcting somebody that Acer isn’t a monitor maker because their monitors are produced by an ODM like Qisda…
