This is the latest evolution of our serial LCD. Included on a single board is a 20x4 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.

This LCD makes for a great gift, because it can be used for so many different projects! For more gift ideas check out the SparkFun Gift Guide!

High quality nice bright display, but not European version.

I've been very pleased with the quality of the display, the screen has a nice brightness and letters are clear and legible, each one 5 x 8 pixels. The serial interface works well only using up a single Arduino I/O pin for all communication, it also seems

Does as advertised with a few niggles

On the plus side, once it's been set-up it works a treat, noting that there is a hint of interference from floursecent lighting under some conditions when the display is dimmed. When operating at 9600 baud I had no issues at all, however, initial attempt

Just the job

Perfect for the application. Up and running within an hour. The screen positions needed a bit of working out but the relevant info is there on the data sheet.
