I'm new to this forum and only have a limited grasp of electronics, Im looking for a replacement LED display module, A customer of mine currently used a display module with a MM5405N driver chip on it, his supplier has told him that they can no longer supply as that chip is obsolete. I'm looking for either a replacent Module or someone who is handy enough to design a new circuit to suit existing Coin Mech and control card in over 100 existing Vending machines. I will try to get more details of exactly what he is using at the moment thanks in Advance apparently its a custom module for a coin mech
