This is the assembled unit. On the left is a
commercially available LCD screen with the MiniDCC© printed circuit board
attached. Commands are sent using a keyboard with each row corresponding
to a loco. The top-right push-button is for emergency stop and the bottom
push button brings up a menu for programming the station and decoders.
|
In this open unit, you can see the keypad, 2
pushbuttons, PC board and the LCD display.

Construction Details
|
|
|
If you plan on keeping the LCD separate, install the header
this way. The cable you make should follow the same pin-out as the LCD.
Notice the Power plug has GND,+5V,DCC pins. |
If you install the PC board directly over the LCD, solder
the header this way, with the power plug still on top.
|
Here you can see how the header looks. Make sure that
soldering the PC board to the LCD is the LAST step. You will not have a
chance to solder anything else to the board. |
