I have a device with an Ethernet connection that the user usually connects to ADSL router. I'd like to offert a 4G connectivity too. I could replace the Ethernet adapter board with a 4G adapter board, but the effort is too high for us. So I'm thinking to use a 4G router, that is similar to ADSL router, but has a 4G modem instead of ADSL model. There are many products available on the market. However I'd like to embed a 4G router in my product for many reasons: better customer impression and the possibility to supply the router when the mains is absent (my product has an internal battery as a secondary power source). So I'm searching for a small embeddable board that features a SIM holder, a 4G modem and 1 or 2 Ethernet ports. I will connect my Ethernet board to this 4G router. Do you know of something similar? How difficult is to design this?

Good luck.No, I'm searching a board with a "full" router OS that features a DHCP server (so my Ethernet board receive automagically an IP address) and will route all incoming packets from 4G connection to the Ethernet port and viceversa. The router OS should try to keep the 4G connection active all the time with the mobile operator. The goal is to avoid changing the firmware on my Ethernet board.

Then things like: https://www.aliexpress.com/item/32974887615.html if you're feeling brave. Theo

Unfortunately the power supply seems only 5Vdc
