So I ordered some 915 Mhz units and thanks to Aliexpress, I received 433 units:angry:

They are offering a partial refund and no sendback or full refund after units returned.
I noticed there are LF and HF resistors with only the LF populated with a near zero ohm link.

Is it a simple matter of swapping these links to change the frequency (and antenna) or is there more to it?

I don’t actually know what the situation is in this case, but I have previously noted that the configuration of radio components on other boards (e.g HopeRF) is not identical between the 433MHz and 915MHz versions.

Yeah, I swapped the links and its working ok, but does not seem to have the range of a factory 915 version… Will continue testing/reading over the weekend
