I am interested in Radxa’s new dual 2.5G networking / PCI-E switch HAT. The “IPEX” connector on the 2.5G HAT looks very similar to the one on the Rock 4’s M.2 PCI-E expansion board - I would like to be able to use the router HAT with my Rock 4B+ boards, if possible.
I would like to know if they are actually the same pin-out - if the ROCK 4 series will be compatible with the HAT if the M.2 to “IPEX” cable from the Rock 4 M.2 expansion board is used. If it is compatible, will it support the full 2x PCI-E lanes that the ASM2806 chip can use, or is only 1x PCI-E lane routed to the ASM2806 on the HAT’s PCB?
Software support is a secondary concern, I would just like to know if they are electrically compatible, since there is no schematic available for either product for me to easily confirm myself.
