Hi there, I’ve carefully reviewed your scope and I’m confident I can design the two stackable Arduino UNO R4 shields exactly as specified. I have hands-on experience with Arduino shield form factors, isolated I/O using relays, MOSFETs and optocouplers, and serial interface design including RS232 while preserving native USB serial access for debugging. I can deliver clean schematics and PCB layouts with proper isolation (5V and 24V relays), stack-through headers and mounting holes, labeled silkscreen and branding, and an RS232 output via screw terminals. The design will integrate cleanly with the UNO R4 and the Zaber XAS01 shield, and be ready for full file handover with IP assigned to you. Feel free to message me so we can review the wiring references and get started. Best regards, Samuel tshibangu
