Description: The serial enabled LCD allows you to control a parallel based LCD over a single-wire serial interface. Included in this product is a black on green 16x2 LCD connected to our serial backpack. The backpack, based around a PIC16LF88, 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.
Note: Though the silkscreen may say ‘5V’, this is a 3.3v Serial LCD. Connect to a 3.3v power source.
Dimensions: 1.425x3.15" - 1" Thick
Based on 1 ratings:
No complaints regarding the functionality. I don’t give it 5 stars for 2 reasons: 1) expensive (but solved my problem, so I can’t complain) and 2) the daughterboard with the serial driver, attached behind the display, is rather bulky, which may complicate many installation scenarios. The pictures in Sparkfun don’t reveal this issue. If the photo from behind was taken at an angle and not straight down you’d see the daughterboard and screw terminal add approximately ½ inch to the depth of the display.
