Good find. I also got a couple of them, only with mine, each included an unsoldered 2x16 LCD and the cost for each pair was lower by about 20% of your price... go figure!

Thanks for locating a proper library, that will come in very handy.

Let us know how your application of this I2C module progresses. I considered using this approach on my CO2 controller, but I had mine working before I could order this module.

I like the idea of I2C, as it used fewer pins, if pins scarcity becomes an issue.

Seems to me that if memory space is sufficient, and available pins are scarce, I2C is the way to go.

On the other hand, if pins are abundant, and memory is scarce, driving the LCD directly could be the best option.

When communicating with the LCD, via I2C, you need to include the LCD library and also the I2C library, right??

Thanks for sharing...

Best,
