Retired: This version has been replaced by the I2C Interface v3. This page is for your reference only.
Convert your 14 or 16 pin parallel interface LCD display into a two wire I2C display. This is a great way to save those pins for other tasks when your project needs an LCD display. It also allows for up to five button inputs though the I2C Interface! Your microprocessor initializes and controls the display.
This module does not come with pin headers. Your LCD display may already have pins if not you can install female headers on the I2C Interface and male pin headers on your LCD display, this way the LCD and interface board can be disconnected easily. Pin headers are available in the Bits and Pieces section. (Resistor R4 for LCD back light current limiting is also not populated. Install the value required for your display if it has back lighting.)
