	The '''Serial Enabled LCD Backpack (SerLCD)''' is a product made by [[wikipedia:Sparkfun Electronics\|Sparkfun]] that allows control of 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 digital device that can communicate via a TTL serial line. The device is designed to handle a wide range of TTL serial baud rates, and currently supports 16 or 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 with 8 bits of data, 1 start bit, 1 stop bit, and no parity (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.

Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps with 8 bits of data, 1 start bit, 1 stop bit, and no parity (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.

== Features ==
* New PIC 16F688 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
* Potentiometer to control contrast
* 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

== Arduino ==
SerLCD works seamlessly with the [[Arduino]] with the option of using the default serial transmission port, or by creating a [[SoftwareSerial]] port.
