I am new to PCB design, and new to Ultiboard. I am working on a project where I have devices with different voltage needs ( 12V, 5V, 3.3V). In my board, I start with 12V (From my power Supply), and then step down that voltage to 5V, and then to 3.3V . Now, all my devices are in different parts of the board, and I need to provide the required voltage for each device.
I was thinking about physically tracing each voltage, but then I would have a lot of inductance and loss in the traces. So another option would be having a power plane, but I would need a 12V power plane, 5V power plane, and a 3.3V power plane. If I only have a 2-layer board, is there a way to have multiple power planes in the same layer (In Ultiboard)?
