Dual Pump Control PCB Design

The system I’m building must drive two stepper-based peristaltic pumps independently at variable speeds, open and close a bank of solenoid valves, and exchange data with a Nextion touchscreen. I already have functional requirements and a block diagram; what I need from you is the complete hardware design that turns those ideas into a production-ready board.

Scope of work
• Capture the full schematic, selecting a suitable microcontroller or SoC, stepper drivers, MOSFET or driver ICs for the solenoids, power-supply stages, and all protections.
• Lay out a compact, low-noise PCB that separates the high-current paths of the pumps and valves from the logic section driving the Nextion display.
• Deliver fabrication files (Gerbers, drill, pick-and-place, and clear assembly drawings) plus a well-structured BOM with manufacturers’ part numbers.

Acceptance criteria
1. Both peristaltic pumps run smoothly across the specified RPM range without missed steps.
2. Each solenoid valve channel switches reliably from the chosen supply voltage with minimal heat buildup.
3. Nextion UART signals meet its timing specs on the assembled board.

When you reply, please focus on projects where you have already integrated stepper drivers, solenoid outputs, or touchscreen interfaces; that practical experience will help me assess fit quickly. CAD tool preference is flexible—as long as you can export industry-standard Gerbers and editable source files, we’re good to go.
