This is the recent development by Dreambrother7. Unlike other products in the market, it uses Raspberry Pico to interface the proprietary Casio bus to modern OLED screen. This allowed to reduce the cost of the project for DIY enthusiasts, by minimizing the BOM and using easily available SSD1309 OLED model. The result is the stunning looking OLED upgrade for whole family of Casio synthesizers.
Deftaudio designed PCB set for this project. The base PCB assembly hosts Pico and OLED screen as one piece. It connects to the adapter board that goes into flex cable slot on Casio. The base PCB has snap off regions to be mounted in FZ-1, FZ-10m/FZ-20m or VZ-10m.
The adapter board is unique for FZ-1 or FZ-10m/FZ-20m/VZ-10m due to a different connector type which is used on rack family. It connects with 10 pin ribbon cable (contact us if you have VZ-1 though).
