**Replacement: **LCD-09396. This product was retired because we have started making LCDs with the PIC module built into one unit. This page is maintained for historical purposes only.

The serial enabled LCD allows you to control a parallel based LCD over a single-wire serial interface. Included in this product is a yellow on blue 16x2 LCD connected to our serial backpack. The backpack, based around a PIC16F88, takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware allows for a number of special commands so you can clear the screen, adjust the backlight brightness, turn the display on/off, and more.

Communication with SerLCD requires 3.3V 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.

• PIC 16F88 utilizes onboard UART for greater communication accuracy
• 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
• 1.425x3.15" - 1" Thick
