Does anyone have EDA schematics for a radio or a surface-mountable sik radio module? #91

Hi there,
I'm trying to embed a sik radio in my AUV robot for long range telemetry in a compact size. I'd love to embed onto my custom-pcb. Ideally I'd love to buy or find an smd radio module I could mount to the PCB. I could also build one into the board including all the SMD components but I can't find any schematics for the hardware. Is the hardware open source?

Id love to buy a module like this, that would be the easiest: https://dwmzone.com/en/data-link-rf-module/135-1649-3dr-radio-telemetry-433mhz-868mhz-915mhz-module-kit.html#/23-center_frequency-915mhz/653-type-3dr_module

I can't quite tell if this store is selling the raw board and their shipping is quite insane.
