Hello, I understand your requirement: a rectangular through-hole LED array (60+ LEDs) with two separate power inputs, where one input drives all LEDs and the second drives only a selected group. The main challenge here is handling both power inputs safely when active at the same time, avoiding backflow and uneven current distribution. I can design a simple and reliable solution using proper current-limiting resistors, grouping logic, and protection (diodes or transistor control) to ensure both channels work independently without interference. I have 12 years of experience in PCB design and embedded systems, with strong expertise in LED circuits and power routing. I will provide a clean schematic, optimized PCB layout (KiCad/Altium), and complete Gerber files ready for manufacturing. The layout will ensure proper spacing, thermal handling, and uniform brightness across all LEDs. I can also share samples of my previous PCB designs on request. Let’s make your design robust and production-ready. Regards, Engineer Muhammad Usman PCB & Designing Expert MCU Specialist

With over a decade of experience in embedded system design and PCB layout, especially with power supply circuits and LED drivers, I am highly skilled in exactly the kind of work you need for your LED array project. I understand how crucial it is to have proper spacing and connections to ensure reliable functionality, something that has been a focal part of my work. I've not only designed LED arrays similar to yours but also worked with through-hole LEDs extensively, which gives me an in-depth understanding of their specific requirements. Furthermore, I've had substantial exposure to parallel operation of power supplies and will ensure that your design accounts for all possible scenarios. Equipped with my mastery over KiCad (Eagle as well), I promise that the layout design for your rectangular LED array PCB will exude attention to detail not just by providing the final Gerber files but also by creating schematic diagrams that make engineering sense. So let's discuss your design requirements further - I'm excited to turn your ideas into functional reality!

Hi there, I am a senior PCB designer and I can route this for you in KiCad today. The logic you are describing requires a simple diode OR-ing circuit to prevent the two power supplies from backfeeding into each other when both are active simultaneously. I will separate the LED array into two isolated buses using Schottky diodes, ensuring Input A powers all LEDs, while Input B safely powers only the targeted selection. I will deliver the schematic, Gerbers, and the exact BOM for the through-hole LEDs and diodes. Let me know the exact dimensions of your rectangular layout, and we can start immediately

@Motarek46

Hi, I've designed multi-layer PCBs for medical and industrial applications — but this project caught my attention for a specific reason: the dual-channel requirement with simultaneous power inputs is the detail most designers will underestimate, and it's actually the most critical part of getting this right. A few things I'd want to confirm before we start: — Are the two channels driving different LED groups at different voltages or currents, or is it purely a selection/subset difference? — When both supplies are active simultaneously, is there a priority channel, or should both operate independently without one back-feeding the other? — What's the LED forward voltage and target current? This determines whether current-limiting resistors are per-LED, per-row, or handled differently — and it significantly affects board real estate in a 60-LED rectangular array. These aren't basic questions — they change the protection topology, the routing strategy, and how I handle the isolation between channels to prevent back-current under simultaneous operation. What I'll deliver: Clean schematic with proper dual-channel isolation and current limiting DFM-ready Gerber files, drill files, and BOM PDF schematic for your records I've attached samples of previous PCB work for your review. I'd rather ask the right questions now than deliver the wrong board later. When can we talk through the details? Regards, Muhammad Tarek.

@Webslinger01

I have strong experience in PCB design and have worked on many custom PCB layouts, including LED-based boards. My Approach: I will design a clean rectangular PCB with proper spacing for 60–100 through-hole LEDs. I will create two separate power input paths so that one powers all LEDs and the other powers only selected LEDs. I will also handle the condition where both inputs are active at the same time by adding proper isolation to avoid conflicts. The layout will be simple, well-organized, and easy to assemble. I will test the design logic in my electronics lab to ensure it works reliably. Deliverables: • Complete schematic diagram • PCB layout files • Gerber files (ready for manufacturing) I also have an electronics lab for testing. I can’t attach previous samples here due to platform limitations, but I can share my past PCB work once we connect.

⭐⭐⭐⭐⭐ I can design this LED array PCB cleanly and make sure the two power-input modes behave correctly, including the case where both channels are active at the same time. The important part here is not just placing 60 LEDs in a rectangle—it’s designing the routing and drive logic so: • Channel A powers all LEDs • Channel B powers only the selected subset • Simultaneous power on both inputs does not backfeed, conflict, or create uneven brightness What I can deliver: • PCB layout for your rectangular through-hole LED array • Schematic showing channel logic, current limiting, and protection • Proper LED spacing and manufacturable routing • Gerber files ready for fabrication My approach: define LED count, dimensions, and the “subset” pattern design the dual-input circuit so both modes are safe and predictable complete PCB layout with clean through-hole spacing deliver schematic + Gerbers Quick questions: • What supply voltage will each power input use? • Are both channels the same voltage, or different? • Do you want current-limiting resistors onboard for every LED/string? • What board dimensions are you targeting? I’ve done custom PCB layouts for LED and embedded hardware and can keep this practical, reliable, and easy to manufacture.

@OyebisiHakeeem

Hello there I can help with your PCB project. I have experience designing compact, production-ready PCBs using [KiCad/Altium], including schematic capture, component selection, PCB layout, DRC/ERC checks, and generating all manufacturing files (Gerbers, BOM, pick-and-place, drill files). board is fully tested in simulation and ready for fabrication. I understand the requirement here is not just placing LEDs on a board, but designing a clean and reliable dual-channel system where power conditions directly control lighting behavior. I would approach this by first defining a robust LED grouping strategy ensuring that when one supply is active all LEDs are driven correctly, and when the second is active only the intended subset responds, without unintended backfeeding or interaction when both supplies are on simultaneously. This typically involves proper isolation (e.g., diode steering or controlled current paths) and careful current limiting to maintain uniform brightness and protect the LEDs. I can start right away and will provide clear communication throughout the process to make sure the board meets your expectations. Looking forward to delivering a clean, production-ready PCB for your project. Best regards, Amos
