When I was working with 433MHz RF, a few times I wound up with the parts and myself located such that it would or wouldn’t work depending on where I stood…
That was back when i was using those godawful green receivers, which are total trash. With the RXB-12 based on the Synoxo receiver IC (SYN470 - SYN480 is comparable, but physically smaller), you’ll probably be fine, as it’s receiving range is so much longer as to make up for that. I’d probably just put pins to connect the receiver with - though the SYN470 is surprisingly easy to implement on a PCB as far as receivers go - I did it a few years back when I wasn’t very good at PCB design yet, I think a few of my inductors and capacitors in the RF section were off, and my range was still 80% of what the RXB-12 was. But the RXB-12 is a buck and change each, so very hard to justify building my own - it’s not worth the time to place the parts on the PCB, even if they were free.
An aside on range: All the transmitter designs you see around are fine. There’s like a 20% difference IIRC between the best (STX882) and the worst of the common ebay ones (again, a couple of new designs have come out since - IIRC the most common green ones were near the top of the pack within that… though it’s easier to build one based on the SYN115, which was closer to the bottom of the pack) - though a $8 US-made transmitter I tested had very poor range, oddly enough.
The receivers, on the other hand, varied between a range of under 50 feet to over 1000 feet under comparable conditions. The RXB-12 was the winner, beating out all the other ones available on ebay at the time (though a few more designs have come on the market since. I haven’t tested those yet). The other SYN-480/SYN470 modules were about the same.
