Serial lcd kit #117 w 20X4 lcd - basic stamp
Note that the LCD #117 Kit operates at 9600 baud.
For Basic Stamp 2, BasicX BX24, Arduino or any processor capable of sending serial at 9600 baud.
(PICAXE enthusiasts should look at the LCD #118 Kit which operates at 2400 baud).
The LCD #117 is a kit, suitable for assembly on a solderless breadboard.
This listing includes the 20X4 LCD shown in the photo. It does not include a PCB.

The LCD #117 Kit provides an interface between a Microchip PIC, Parallax Stamp, BX24, Arduino or similar and an
LCD having an HD44780 interface. I believe it is the most powerful serial to LCD unit available on the market
and the least expensive. I have sold several thousand over the past three years.
* 9600 Baud TTL Interface - Non Inverted. For operation with a PC or similar using RS232 levels a
MAX232 or similar is required
* Programmable LCD Geometry (2X16, 2X20, 2X24, 2X40, 4X16, 4X20) - saved in EEPROM.
* Eight User Defined Characters (saved in EEPROM).
* Programmable Tab Size (saved in EEPROM).
* Programmable Cursor Style (saved in EEPROM).
* Output for "beep" function. (The interfacing audible device is not included with this kit).
* Rich Cursor Instruction Set including, clear LCD, clear current line, cursor to defined line, cursor to
defined column, cursor up, down, back, foward, new line and "beep". * 3 block wide and 4 block wide "big number" capability.
* Customized splash display screen.
* Ouput and power transistor for varying the intensity of an LED backlight.
* Four addressable TTL level outputs (15 mA)
* 20X4 LCD with Yellow / Green LED backlight.
* Programmed PIC Processor (18-pin DIP).
* 4.7K Resistor for Processor Reset Terminal
* 330 and 4.7K Resistor for biasing contrast on the interfacing LCD.
* TIP-41 NPN transistor and 330 Ohm base resistor for controlling LED backlight..
* Lengths of 22 awg solid wire (four colors) suitable for use with a solderless breadboard.
* 20 X 4 LCD with Yellow / Green LED backlight.
* 16-pin header for the LCD.
* 4.7 Ohm series resistor for limiting the LED backlight current to less than 250 mA.
Note that a source of +5 VDC is required. The current drain is less than 10 mA. However, when using the
LED backlight, up to 200 mA may be required.
For additional details and sample routines, please see my web site.
Note that I can supply programmed PICs in quantity for those who desire to incorporate this design into a
product. Please contact me for pricing.
* Australia, New Zealand, Singapore - $5.25.
