Raspberry Pi 16x2 LCD RPi Plate (with KeyPad + RGB LED)

• This product integrates a LCD1602, RGB LED and five-key button (Up/Down/Left/Right/Select). Due to limited IO ports on Rpi, it also has a built-in IIC interface extension chip used to connect with Rpi. It is easier to use Python to program, just call function libraries.
• LCD1602 has screen output which can display two rows with 16 English letters each row. It is suitable for display some simple text information.
• Five-key button along with LCD1602 provide input interface to make menu selection.
• RGB LED can display seven colors, depending on different input levels.
• This plug-and-play product can be directly plugged into Rpi GPIO without later welding.
