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.

Features:

Two line (2 x 16) characters

5x8 dots with cursor line

+5V supply

Serial Interface I2C, SPI or RS232/TTL

Display mode: STN/Blue/Negative/Transmissive

High operating temperature range: -20C - +70C

Driver: SPLC780D with PIC16F690 providing high level functions. (These functions provide ease of use without needing to understand the low level LCD controller instructions and timing requirements.)

Direct access to low level controller is available for advanced control.

Space reserved for eight custom characters.

50 software settable contrast levels

8 software settable brightness levels for backlighting.

No additional components required to drive backlight.
