SparkFun Electronics will be closed on July 3rd, 2015 in observance of Independence Day. Any orders placed after 2:00pm MT on July 2nd will be shipped out after the weekend. Thanks!
Description: The SparkFun Serial Enabled LCD Backpack allows you to control a parallel based LCD over a single-wire serial interface. The SerLCD backpack takes care of all the HD44780 commands allowing seamless integration with any micro that can communicate over a wide range of TTL serial baud rates. The SerLCD currently supports 16 and 20 character wide screens with 2 or 4 lines of display.
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, 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: The datasheet incorrectly identifies the PIC as a 16F688, when it’s actually a 16LF88. Sorry for blowing your mind.

The I2C Backpack did eventually work. I had a lot of trouble finding and installing the files to make it work. working with files in the Arduino IDE. is hard for me to understand. unzipping and putting files into folders and then having to rename them and move them around is above my ability. Spark fun products are good I have used your products in the past and will continue to buy from Spark Fun. It would be nice for people like me, if you offer software, to make it auto install and no errors!!! and also a good schematic would be nice. Keep up the good work.
I had this up and working very quickly. I only gave it 4 stars because: There is discrepancy on the interwebs on whether it requires 5v or 3.3. Since I used this with an electric imp I had to pull in a 5v power source. Documentation seemed lacking on the pinouts to connect this to the LCD. I’m curious if you can send special characters to the LCD through this board. I didn’t see anything in the documentation on that either… All in all, provides basic control of an LCD with 1 wire.
