saw the news of E25.
want to provide some feedback.
I like the look of the case.
About the two slots (M2 B key and mini pcie).
Optional support for WiFi & Bluetooth via mini PCIe socket (multiplexed with 5G)
Optional support for 4G LTE via M.2 socket, 4G or 5G via mini PCIe socket; SIM card slot
My questions are
- does it provide USB 3.0 interface via the M.2 B key?
- does it provide pcie interface via the M.2 B key?
- how the bandwidth is shared between M.2 B key slot and the mini pcie slot?
feedback or suggestion.
The power requirement of wifi 6E (ax 6GHz) is very high.
Many aged router board doesn’t provide enough power on their mini pcie slot to drive a wifi 6E ap card.
Please kindly pay more attention to this.
For a device that only has two expansion slots (M.2 B key for 5G modem, M.2 E key or mini pcie for wifi ap), we need a dual bands dual concurrent card.
Currently, the ax ap card that has best openwrt support is AsiaRF AW7915-NPD. (dual band dual concurrent)
It has MediaTek chip. If you were to offer us a wifi 6E card, please consider provide hardware that openwrt support.

Many network application boards provide three expansion slots.
[ 4G/5G modem && 2.4G AP && 5.0G AP ]
Many network application boards have one GbE that use a switch to spilt into 4 GbE ports.
A very popular one like omnia (open source hardware, you know.)
I would prefer the same, and keep the pcie lanes for proper
[ M.2 B key slot && (M.2 E key || mini pcie) ]
The reasoning behind this is that, the max one can get from a 5G modem probably doesn’t exceed 1gbps, multiple real 1GbE ports can’t use all bandwidth.
It is likely the shared bandwidth pcie lanes [ M.2 B && (M.2 E || mini pcie) ] become the bottleneck.
I don’t really care about sata on a router. I prefer to not have sata. Too big. Some people prefer to have it. I prefer removable emmc. If additional storage were possible, I would prefer on M.2 pcie || M.2 sata || minipcie sata. (without compromising the dedicated pcie lanes for the 5G and wifi)
Looking forward to an openwrt 5G router from Radxa.
