Hello Rob, It is not about the HD44780 on the well-known 6-pin connection. It is about an interface that you can stick on such an LCD and then control the thing with I2C, (so only two connections instead of 6). The PCF8574 is a different thing. The link that Pinhead indicated (to AZ is about such an interface.)
