Shown with some optional or user-supplied components and breadboard

Many microcontroller projects could benefit from a full-blown user interface, but developing one can be prohibitive. Now, with the GP-2 kit you can connect an ordinary PS/2 keyboard or mouse to an RS232 port. This easy-to-build kit has the same features as our PAK-VIa chip, but it an entire kit with a PC board, power supply, and RS232 interface. The kit has many exciting features:

32 character buffer!

Cooked mode handles the keyboard completely and delivers ASCII characters

Raw mode allows complete control over the keyboard (or mouse)

Hardware (RTS/CTS) handshaking

DB9, DCE RS232 connector

True RS232 from onboard 5V supply

Includes PS/2 connector

This versatile kit can be customized to use different power supplies or provide TTL level outputs, if required. Imagine the power of a PS/2 keyboard in your next project. You can use an industrial keyboard in a harsh environment or a small keyboard or numeric keypad where space is at a premium.

PAK-VI (chip version)

GP-5 (for mice)

PAK-XI (chip for mice)

All you supply is a keyboard and a DC power supply (the GP-2 has an onboard 5V regulator, or you can supply 5V regulated directly to it). Now your Basic Stamp, PIC, or other micro project can have a full keyboard.

This is essentially a board version of our PAK-VIa (see the PAK-VIa manual). This kit is based on our GPMPU28 board, and you may want to read the manual for that board as well.

Please note that this is a kit and does require soldering and basic electronic tools. This allows you to customize the board to fit your needs. All the parts are through hole, and the solder masked board is very easy to assemble.
