updated_uPD7220_design.zipUpdated schematic, with all KiCad design files. This is a bit messed up due to the KiCad version change and transfer, but the PCB design should work fine as is. This fixes the connections to the color resistor networks, and fixes the oscillator.Zip Archive - 3.62 MB - 05/08/2024 at 01:51 |
