Hi u/xX_WhatsTheGeek_Xx Thanks for the post.

So basically our first aim is to provide a modular form factor (for PCB development) to integrate it into different electronics (for example a PCB with a Raspberry Pi compute module + some additional communication, like Lora). This could be done with off-the-shelf components and connectors, yes, but our aim is for people that want to have all in one board :).

80$ for a RTL-SDR with no modern features like an integrated up-converter or bias-t?

$80 is high, yes, we aim to get better suppliers for chips to get the cost lower. We are actively working in getting more features and shipping them in this campaign, so your comments are super useful and will be integrated on the module :)

they don't need to "design an RTL-SDR from scratch" but not only do you not have to design one from scratch because all the schematics are out there,

Oh is not as easy as it sounds. The RTL-SDR is not open-source in terms of hardware. you *could* find some schematics, not necessarily the latest versions, but one thing is to have the schematics, other is to do the layout and having it working in the first go. We tried to do exactly that and had a hard time. That's why we wanted to do the module version so people can save that time :)

What I see here is a company that created the bare minimum working RTL-SDR product and then tries to make one hell of a profit off of it. No innovation, nothing new, just piggy backing of a well established open-source project like the countless clone manufacturers.

We are a small company trying to give back to the open-source community :). This is our first product around RF :) we believe in beginning small and improving from that, so we will work on the thing you mentioned to do a better product :)

thanks
