    I needed all my IO lines and there was no room for a display to connect. This board was the answer via the I2C interface I was able to complete my project. You can solder the pcb on the back of the LCD Display through the connection pins.

    an alternative library for Arduino can be found here:
    (don’t forget to use the right I2C address)

    Good module.
    Be sure to power it with 5V, with 3.3 it will not work.

    This is vey nice to use with a 1602 LCD display, as it allows to use it with only two pins (plus vcc and GND) .
