Serial LCD Controller Module Without LCD
It is not very easy to control those LCD1602, LCD1604 or LCD2004 modules, especially for Arduino users. It will take as much as 16 pins of Arduino. If you want to control other modules with Arduino meanwhile, of course, you will find many wires and probably no enough available pins on Arduino board.
So we designed this UART controller. It serves as a display card for LCD screen. It is compatible with LCD1602, LCD1604 and LCD2004. It only takes 4 pins on Arduino (in fact, only 2 data pins- Tx and Rx). You could control it via hardware serial interface on Arduino, or any 2 data pins with SoftSerial library.
We already have an Arduino Serial LCD-1602 Shield in our shop. But it can only display 32 letters. Now we designed UART LCD2004 module which can display 80 letters.
Different with UART LCD1602, we seperate the LCD and display card. When it comes up to change the LCD, this design is very helpful. For example, you can change the blue LCD to a green one, or you can change a new one if you broken the LCD carelessly .
The serial command is completely compatible with UART LCD1602. So if you want to update your dispaly, it saves you the trouble to rewrite the code. It is powered by 5V, which is compatible with most microcontrollers. Also, the interface is compatible with Arduino Sensor Board, in case you already one.
This module can be compatible with LCD1602,LCD1604 and LCD2004. It only takes 4 pins on Arduino (in fact, only 2 data pins- Tx and Rx). You could control it via hardware serial interface on Arduino, or any 2 data pins with SoftSerial library.
