TinyTrak4 DK Adapter
Manual version 1.3
The TinyTrak4 DK adapter is a small circuit board designed to ease the connection of a display and a
PS/2 Keyboard to the TinyTrak4 kit and surface mount built units. It is available as a kit, or as a built
unit.
The components of the TinyTrak4 DK adapter are:
•The printed circuit board
•1x16 0.1” header socket (to be mounted to the PCB)
•1x16 0.1” header posts (to be mounted to the
display)
•2x5 right angle 0.1” header posts (for the ribbon
cable connection) See Note below
•PS/2 PCB mount socket (for the keyboard
connection)
•10K variable resistor / potentiometer (for display
contrast adjustment)
•0.1uf capacitor
•62 ohm resistor (sometimes included with the
display)
•6” 10 conductor ribbon cable with 2x5 IDC
connectors on each end
Assembly is fairly straightforward. The included image should help with component placement. All
components should be added to the printed side of the PCB. The 1x16 header posts should be
inserted from the underside of the display, with the shorter post through the holes, and soldered on
the top side of the display.
Note: It is recommended that the ribbon cable be connected to the 2x5 right angle header posts (on
the straight side) before soldering to insure the header does not sit too close to the circuit board
The ribbon cable should be connected with the red stripe nearest the variable resistor. Either side of
the ribbon cable can be connected to the adapter. The other side of the ribbon cable can be
connected directly to J9 on the built TinyTrak4 with surface mount parts as shown below. Note the
red stripe on the
ribbon cable should
be nearest the center
of the PCB. The
ribbon cable can be
replaced with a
longer cable if
desired, up to 15 feet.
