Embedded CPU utilizes onboard UART for greater communication accuracy
9600 baud rate
Greater processing speed at 50MHz
Incoming buffer stores up to 80 characters
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.

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. I...
