Hello, you need a 12 V power control circuit that latches on when a push-button is pressed and can be commanded to shut down by an external microcontroller. It must be built from discrete and integrated parts, switch within 30–50 ms, and be proven on a breadboard with video documentation before producing a PCB. I will design the circuit following power safety practices and PCB layout rules per IPC-2221 ensuring it is production-friendly. Following are the deliverables: • Schematic design and PCB layout • Gerber and Drill files for manufacturing • Bill of materials • Breadboard testing with video documentation I wanted to ask: • What max continuous current (A) must the switch handle? • What voltage level will the MCU GPIO use to command shutdown (e.g., 3.3 V or 5 V)? I have 7+ years of experience in similar projects like: • 12 V Push-Button & MCU-Controlled Power Latching Circuit Design • MOSFET-based load switching with low Rds(on) and thermal management I am proficient in software like: • Altium Designer, KiCAD, EAGLE Thank you for considering my proposal. Looking forward to collaborating with you on this project. Best Regards, Abubakar
