I like specifications of raspberry pi zero, and i want to make similar router-like device. The device is intended for some statistics monitoring, it should collect statistic from multiple hosts and aggregate it. Number of hosts is huge, and stability\latency is very important, so WiFI cannot be used. Device should have just simple web interface via Ethernet (like home routers usually do). But the board lacks ethernet port, and it have (unwanted/expensive) hdmi port. I dont need graphics at all.
What platforms, or boards are usually used for this product group? (What model usually used by developers while developing/debugging firmware for router-like or IoT-like devices?)
