is possible to power up the imx233 with the MOD-POE-V2? as i see there are 2 ethernet input, can i use only one port to power the board and communicate with ethernet contemporary? do i need other accessories or i can boot a debian based system with imx232+poe+sd card + an external switch with poe?
Unless someone explains how or you work out how to do it safely (without board damage), then no.
You'd need to use a separate PoE splitter for this.
