Additional Information

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 CPU. 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. 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 can be used for so many different projects! It's a great gift.

Most Helpful Customer Reviews

I got this because of ease of use of serial TTL and the price compared to competitors.
Unfortunately documentation for Serial backpack on this LCD is does not exist.
I found the following link in another LCD review with the same backpack:
https://s3-ap-northeast-1.amazonaws.com/sain-amzn/20/20-111-918/TTL+2004+12864.zip
but the sample included there boils down to following:
There is a very limited set of commands available:

Serial.begin(9600); //This seems to be only available option
Serial.write(0x8A);
Serial.write(0xA8); //this line and line above it indicate start of text
Serial.write(0x00); //row
Serial.write(0x00); //column
Serial.write(0x05); //number of bytes to be written
Serial.print("Hello"); // the actual text
...
Serial.write(0x8A);
Serial.write(0xA8);
Serial.write(0xFF);
Serial.write(0xFF); // 0xFF 0xFF clears screen

These are all the commands available.
