UART LCD Controller Module -- Arduino compatible

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.

It is pretty easy to use it. Just connect it with Arduin via UART interface:

Then send command to display anything you want on the screen.

It is compatible with LCD1602, LCD1604 and LCD2004:
