16 keys keyboard board
A question, a problem or a suggestion, don't hesitate : a little email
A combined keyboard/leds board with:
- 16 keys,
- 6 leds.
(To be used with libcla1.zip library)
This board is using my old bus standard and is directly connectable to the 8031 "base 1" board using DIL 16 connectors. For a new project, I recommend to use the new standard.

The place of the different components of the board.
Don't forget the 5 straps on the component side. The connector is a DIL 16 one but on my boards, I have preferred to solder directly the wire on the solder side of the board.
Solder side
No particular difficulty for this board.
