16x2 Character LCD - Serial I2C/SPI/RS232-TTL


Serial LCD 16x2

This is a great little LCD display. With the integrated serial interface no additional backpack converter is required. Offering several serial interfaces, you can choose the one that best fits your project needs. Using only one i/o pin you can drive it with either hardware or software serial. If you are already using a I2C bus you can assign the LCD a unique ID and add it to your existing two wire I2C bus (great if you need to drive multiple LCD's at once.) The SPI interface is also available.
