This is a low cost 16x2 LCD module which can be used out of the box with the Arduino LiquidCrystal Library and operate in 4-bit and 8-bit mode.
Features:
- 16x2 LCD module with black characters and apple-green backlight
- User-settable contrast
- Can be run without or with dimmed background light (just use a PWM output with current limiting resistor to control backlight)
Note: There are few differences to our other 1602 LCD modules which you should take careful note of before using these displays. These differences are outlined below:
- Pin1 and Pin2 reversed: Normal HD44780 modules have GND on Pin1 and 5V on Pin2, this display has 5V on Pin1 and GND on Pin2 !
- The connector for the module is on the left side for data lines and supply voltage and on the right side for background light (see image).
Elsewise the displays just work like expected and the sideways connector can be an advantage depending on your enclosure.
