DC Supply – Bill of Materials
- Kits are available from IEEE — contact the current IEEE representative, listed on the About page.
- The BoM includes everything needed to make the DC supply PCB. To use it, you will need an input supply, like a 12-VRMS wall-plug transformer or a DC supply with an voltage bigger than whatever output voltage you want to use.
