SparkFun LCD-09395 Serial Enabled 16x2 LCD - White on Black 5V Discontinued

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.


  • 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


  • PCB: 103x36mm
  • LCD: 71.4x26.4mm

    The first unit to arrive did strange things when characters were sent to it. However, this was returned and replaced without any hassle or delay. The second unit performed as expected being much easier to interface to using a serial port. Disappointed tha

    Totally worth the money compared to the basic parallel ones - no need to dick about soldering 10 pins / external resisters/ using loads of board pins etc. Literally just plug in the three wires and your good to go. I used the following code to get started
