I checked out the website, and the pc1602-L looks like a direct replacement (other than the background colour) for the Optrex displays I am currently using. Unfortunately Optrex has obsoleted some of their character displays so the order of the day is to locate alternate replacements for my design.

I am considering to redesign using one of the graphic displays instead. have you worked with any of the powertip graphic displays, and if so, any tips or suggestions?
