Overview
The Flying Electron LCD Adapter Board is designed to allow easy connection of an LCD display to a
microcontroller by incorporating all of the external hardware needed to take full advantage of all the
features of an HD44780 based LCD such as the LCD IO bus, contrast control, and 5V backlight control.
Available Option: Optrex DMC-24227 24x2 LCD (Pulled from working equipment, cosmetic blemishes)
Example of Use
Step 1 - Connect 14 pin ribbon cable from LCD to the HD44780 Header.
Step 2 - Connect 10 pin ribbon cable from IO Port Header to microcontroller.
Step 3 - Connect 5V Backlight to Backlight Header. (Optional)
Step 4 - Power on.
Step 5 - Adjust contrast using Contrast Adjust Potentiometer.
Step 6 - Run microcontroller program to communicate to LCD through IO Port.
Features
Interfaces with cheap standard HD44780 LCDs
Designed to work with the millions of cheap character based LCDs in existance. If an LCD is character
based, it's most likely an HD44780 LCD.
Contrast Adjust Potentiometer
Allows easy adjustment of LCD contrast with no external components.
Backlight control
Allows turning on and off a 5V backlight from the microcontroller's program. Higher voltage backlights
can also be switched by only using the Switched GND pin. 150ma Maximum Current.
Easy Microcontroller Interface
Designed to interface with a standard 8 bit microcontroller IO port. Includes resistor protection to
protect the microcontroller's IO port from LCD signal contentions, spikes, and short circuits.
Dimensions
• 2" x 1.25"
• 2 mounting holes spaced 1.75" on center for easy mounting to a chassis
