!!Hardware / LCD Board Information
[+The LCD appears to be based on the Geeetech Graphics LCD with some changes to the pinout and connector+]

!!!!LCD Pins / EStop:
There is ONLY the 10 pin LCD connector and the ICSP port.
In the LCD standard in the Reprap community, there is LCD (SPi protocol so at least 3 pins) you go the encoder+ click, so that's 3 more pins, then you got beeper 1 pin, and Estop is a standard in he interface 1 pin. If 2 pins are power and ground, that's all 10 pins accounted for.
The only other connector is the ISCP and that's in parallel with the SD card.
NO in most Repraps, the Estop is just an input to the firmware to reset and there are options on HOW the firmware handles it.
NO it is not a power kill, but on some boards it can command a power supply shutdown. Melzi doesn't have any free pins to control a PSU.
.
This is the low end of the Reprap open source. The Melzi is meant to be a low cost no extra options kind of board. It works, it prints well, but it is NOT every bell and whistle option.
That said, it follows standards established in the Reprap community. It runs Reprap firmware. The LCD interface board follows the minimum number of user control inputs- LCD, encoder+click and Estop along with alarm or beeper.
