Changing the resistor strapping on the RAK15000 EEPROM

I need to change the resistor strapping so that I can power the RAK15000 from 3V3 rather than 3V3_S. (It’s all a knock on effect because the LNA_EN on the RAK12500 doesn’t connect to a FET, so the only way to power down my active antenna is to pull the whole 3V3_S power rail and I don’t want to shut down the RAK15000 EEPROM too. This isn’t even an option on the RAK15005 FRAM modules even though they draw nearly nothing, so that’s why I’m going back to the EEPROMs).

I’m also planning to use two of the RAK 15000 modules so I need to restrap the A2 address pin on one of them.

Is there any documentation that shows the location of resistors R3, R4, R5 and R6. I suppose I could bell them out, but if I could get a picture it would remove an opportunity for me to get to wrong.

Thanks

That’s one of the older modules. Only have this image for the components

Great. That’s all I need. Thanks
