As the price of ICL7107 decreased dramatically through the time, I decided to use my stocks to build a modules for various purposes.

Therefore I designed the PCB, which is divided into two parts, but could be manufactured as one. The 2 parts are connected with right angle 25 pin header, which allows to use LED display vertically, while the driver is horizontally oriented.
