Olimex rt5350f with OpenWRT

Olimex has a nice board with the Ralink rt5350 MIPS SoC (32 MB RAM, 8 MB SPI flash) with integrated 802.11n wifi. About 24 € with the base port providing two relays, two NICs, USB.

It comes with OpenWRT 15.05-rc3 pre-installed, kernel 3.18.19.

The serial port is 3v3 with 57600 8N1. The left ethernet port is LAN, the right/middle port is WAN.
