Hi, I need to connect an external microphone to the CON10 connector of the a MarkII mini2440 board and need help to solve some issues: a) What type of microphone can i connect to the external microphone input? b) What connections should i use? c) Waht is the CON10 pinout (the schematics pdf is confusing because on the board we have a 3 pin connector, but in the schematics the connect designated as CON10 has 4 pins)
