LCD 2x16 , Serial Interface

This is the latest evolution of our serial LCD. Included on a single board is a 16x2 LCD and an embedded circuit based around a PIC 16F88. The on-board PIC takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware also 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 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 (VDD), ground (GND) and RX pins are all broken out to both a 0.1" pitch header as well as a 3-pin JST connector. SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the back of the display to adjust the contrast.

Quick Spec

  • Embedded PIC 16F88 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

Sample Code


// Attach the serial display's RX line to digital pin 2
SoftwareSerial mySerial(3,2); // pin 2 = TX, pin 3 = RX (unused)

void setup()
  mySerial.begin(9600); // set up serial port for 9600 baud
  delay(500); // wait for display to boot up

void loop()
  mySerial.write(254); // move cursor to beginning of first line

  mySerial.write("                "); // clear display
  mySerial.write("                ");

  mySerial.write(254); // move cursor to beginning of first line
  mySerial.write("Hello, world!");

  while(1); // wait forever
