i like the part where it's compatible with either 5v, 3.3v, 2.5v, or 1.8v. i understand it all boils down to a personal choice but i'm just not keen on the idea of de-soldering or soldering of additional components on the board to get the uart voltage right.
now my next task is to find out exactly what voltage uart the ea7500 uses because it's not clear to me after reading this post. was it 1.8v or 3.3v?
