The serial enabled LCD backpack allows you to control a parallel based LCD over a single-wire serial interface.
The SerLCD backpack takes care of all the HD44780 commands allowing seamless integration with any micro that can communicate over a wide range of TTL serial baud rates.
The SerLCD currently supports 16 and 20 character wide screens with 2 or 4 lines of display.

Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1).
You can adjust the baud to any standard rate between 2400 and 38400bps. The power, ground and RX pins are all broken out to a 3.5mm pitch screw terminal.

SerLCD has the ability to dim the backlight to conserve power if needed.
There is also a potentiometer on the backpack to adjust the contrast.

Note: The datasheet incorrectly identifies the PIC as a 16F688, when it's actually a 16LF88. Sorry for blowing your mind.

Features:

• PIC 16LF88 utilizes onboard UART for greater communication accuracy
• Adjustable baud rates of 2400, 4800, 9600 (default), 14400, 19200 and 38400
• Operational Backspace
• Greater processing speed at 10MHz
• Incoming buffer stores up to 80 characters
• Backlight transistor can handle up to 1A
• Pulse width modulation of backlight allows direct control of backlight brightness and current consumption
• All surface mount design allows a backpack that is half the size of the original
• Faster boot-up time
• Boot-up display can be turned on/off  via firmware
• User definable splash screen
