I2C Serial Adapter

This is an I2C Serial Adapter LCD Daughter board that is RoHS compliant and can be linked to a normal 162- or 204-Character Display Module that supports 4-bit mode. 4-bit mode is supported by all Character Modules supplied on our site, as well as practically all commercially available 162 and 204-line character modules.

The PCF8574 I2C chip on this board translates serial I2C data to parallel data for the LCD display. There are numerous examples of utilizing this board with Arduino on the internet. Look for "Arduino LCD PCF8574" in the search engine. The I2C address is set to 0x3F by default, but three solder jumpers on the board allow you to change it. This allows you to manage up to three LCD monitors from a single I2C bus.
