Today I cleaned up the schematic by organizing it into more readable sections. I updated the op-amp power inputs to use ±15 V supplies and added a DAC input (0.0 V to 3.3 V). While routing, I realized I had forgotten to connect the ground for the dual ±15 V power input, so I corrected that. I also added a dedicated 3.3 V input from the microcontroller to feed the op-amp buffer, providing a lower impedance reference voltage.
also the routing was a breeze as there werent many components, so after arranging the components, i routed them and made the silkscreen much more organized and added power labels for easier use!
so my work is done for now i might try to add my own doodles on the pcb i have the time, i now need to complete my repo and BOM
