    Hi Bakos, The IC model was taken from KiCAD library. maybe it was not correct there. you can use the schematic as base and create your own board using different footprint. Thanks

    Hi Jose, this is an simple I/O expander board made for driving 16X2 or 20X4 LCD panels. You can use it just as a serial to parallel converter and use them to drive your required 7-segment displays. please note the current requirement and the current driving capability of the IC are in range.
