Hi All I am trying to bring up two RM500U-CN by putting them to Slot1 and Slot 2 on the Banana Pi R4 Pro. But It seems from the documentation and other posts that RM500U-CN is only supported on SIM1 slot: Is this correct ? Is there a way to have two RM500U-CN simultaneously?
- SIM1 is mapped to the M.2 Key-B slot (CN16) for modules such as:
- Quectel RM500U‑CN
- Quectel RM500Q‑GL
- Quectel RM520N‑GL
- Quectel EM05
- SIM2 is mapped to mPCIe slot CN12 (typically used for EC25).
- SIM3 is mapped to mPCIe slot CN14 (also for EC25 or similar modules)
