My point was that adverts often do not quote the scope of the use of the ‘LoRa’ devices they are selling.
You are, I am afraid, being rather unfair to seller of the item at the askers link, because while there are pieces of information which are not well stated, the sorts of things you are claiming are missing, are actually right there.
If you will take time to actually visit the link, you will see that not only is it a bare SX127x, the SPI and DIO pins are clearly silkscreened on the module itself. Most forum members and most of their likely customers would also presumably recognize the board design - it happens to be that of the most widely known family of SPI lora modules on the planet, or a copy thereof. People using that do not expect software from the board seller, they use standard open source code as documented in several threads on this forum.
In contrast, if you visit ebyte’s site you will see that they show UART rather than SPI pins.
