64×80 mm 320-RGB LED PCB Design

@MuhammadUzair16

Hi, I am an embedded systems engineer with over 16 years of experience designing compact PCBs and taking consumer products from concept through production, including firmware support and manufacturing handoff. I can create this 64 × 80 mm, two-layer KiCad 7 board with all 320 LEDs precisely placed on the 4 mm grid, a clean serpentine data chain, rear-side connection pads, and power/ground routing sized for the stated peak current. I will deliver the complete KiCad source, Gerbers, drill files, IPC-356 netlist, BOM, centroid/PnP data, and fabrication notes for lead-free HASL. Before delivery, I will run KiCad DRC and prepare the outputs to satisfy common JLCPCB/PCBWay manufacturing constraints. Should I use the exact WS2812C-2020 part, or may I select a pin-compatible 2020 LED that is readily available for assembly? I would be glad to discuss the details and get started.

Hello, I can design your 320-pixel RGB LED PCB in KiCad 7 and prepare it for production. I’ll create the precise 16×20 grid with 4 mm pitch, using WS2812C-2020 or a suitable equivalent. The design will use a straightforward 2-layer stack-up, with all LEDs on the top side and 5V, GND, DIN, and DOUT connections on the rear. I’ll ensure proper power distribution for the ~5A peak current, clean serpentine data routing for board-to-board chaining, decoupling, grounding, and manufacturability for JLCPCB/PCBWay. Deliverables include KiCad source files, Gerbers, drill files, IPC-356 netlist, BOM, PnP file, and fabrication notes. I have experience with dense PCB layouts, power routing, and production-ready designs. Ready to start immediately. Best regards, Mahmoud

⭐⭐⭐⭐⭐ I can lay this out as a precise 16 × 20 WS2812C-2020 matrix, with the 320 LEDs locked to the required 4 mm centre-to-centre grid and the board kept within the ~64 × 80 mm envelope. I’ll specifically handle the design around your manufacturing requirements: • All LEDs on the top layer with verified 2020 footprint/land pattern • Rear-side 5 V, GND, DIN and DOUT solder points • Two-layer FR-4 layout optimized for low-cost fabrication • Power distribution sized for approximately 5 A peak, with sensible current paths and local decoupling • Clean serpentine DIN/DOUT routing for reliable cascading between boards • Ground stitching/vias where beneficial without compromising the compact grid • Accurate board outline, mounting/edge-chain considerations and silkscreen • KiCad 7 source plus Gerbers, drills, IPC-356, PnP and BOM Before release I’ll run KiCad DRC and a JLCPCB manufacturing/pre-check, and verify the LED coordinates against the 4 mm grid so there is no accumulated placement error across the matrix. I’ll also confirm the requested lead-free HASL finish and fabrication notes in the final package. If you provide the reference image and the exact WS2812C-2020 part/footprint you intend to use, I can start with the grid and power architecture immediately.

Hi, I’m a Senior PCB Design Engineer with 7+ years of experience in compact LED, IoT, and mixed-signal hardware, delivering 100+ production-ready PCB designs using KiCad and Altium. I have designed 2-layer boards with high-density component placement, controlled power distribution, and fabrication-ready outputs validated through DRC and manufacturer checks. Approach ✅ I will build the 16×20 WS2812C-2020 grid with exact 4 mm pitch and mechanical alignment within the 64×80 mm outline. ✅ I will route 5 V/GND with low-impedance copper sized for ~5 A peak, using strategic vias and ground stitching while maintaining clean thermal paths. ✅ I will implement a robust serpentine DIN/DOUT chain with rear-side solder points and edge-to-edge cascading capability. ✅ I will run KiCad 7 DRC, verify manufacturability against JLCPCB/PCBWay rules, and deliver Gerbers, drill, IPC-356, PnP, BOM, and source files. Questions ✅Can you confirm the exact LED part number/footprint and whether the 5 A peak represents the maximum current for one complete 320-LED board? ✅ Should DIN/DOUT be positioned on specific board edges for the intended edge-to-edge mechanical chain? Best, Yaroslav

Hello, This project is a strong fit for my PCB layout background. I can create a compact 2-layer KiCad design for the 16x20 WS2812C-2020 matrix, with the LEDs aligned on a 4 mm grid, rear-side solder points, and production-ready files for fabrication. My focus would be: - exact LED placement and footprint consistency - clean 5 V / GND routing for the expected current - straightforward serpentine data chaining between boards - DRC-clean KiCad files - Gerbers, drill, BOM, and centroid/PnP deliverables If you’d like, I can start by reviewing the mechanical constraints and defining the board outline and LED grid first. Best regards

✅✅✅✅✅ I can design this as a production-ready 2-layer KiCad 7 board with the 320 LEDs precisely aligned to the required 16 × 20 grid and 4 mm center-to-center pitch. The mechanical accuracy will be treated as a primary requirement, not something checked at the end. I’ll establish the grid and board coordinates first, then build the electrical layout around it while keeping all LEDs on the top and the 5 V/GND/DIN/DOUT connections accessible from the rear. My approach: Verify the WS2812C-2020 footprint, orientation and exact 4 mm grid Lay out the 320-pixel array with consistent coordinates Design 5 V/GND distribution for the ~5 A peak requirement Route a clean, manufacturable DIN/DOUT serpentine chain Add appropriate vias/ground stitching and edge-to-edge chaining provisions Run KiCad DRC and prepare fabrication/PnP outputs I’ll deliver the KiCad 7 source, Gerbers, drill, IPC-356 netlist, centroid/PnP file, BOM and fabrication note specifying the 2-layer stack-up and lead-free HASL finish. I’ll also check the final files against JLCPCB’s manufacturing constraints so the design is ready for a straightforward prototype order. If you confirm the exact LED part number/brightness-current requirement and the edge-to-edge connector/solder-pad arrangement shown in the reference image, I can finalize the routing strategy around those details.

Hi, I’ve carefully reviewed your requirements, and this is a great fit for my PCB layout experience. I can design a clean, production-ready 2-layer LED matrix with all 320 addressable RGB LEDs accurately aligned in the 16 × 20 grid at the required 4 mm pitch. I’ll focus on maintaining a clean serpentine data path for easy board-to-board chaining, while optimizing the 5V and GND distribution for the expected current using suitable copper pours, trace widths, and stitching vias. I’ll also ensure the rear-side solder points are properly integrated without compromising the LED alignment or routing. The final design will be fully DRC-checked and prepared for common manufacturers such as JLCPCB or PCBWay, including Gerbers, drill files, BOM, pick-and-place data, and the KiCad source project. Please feel free to check my portfolio for examples of my previous PCB designs. Best regards, Ahmed Yahia

HI, KINDLY READ THROUGH MY PROPOSAL The key challenge is fitting 320 WS2812C-2020 LEDs into a precise 16×20, 4 mm grid while maintaining reliable power and edge-to-edge data chaining. I’m a PCB Design Engineer with 6 years’ experience. I’ll create the 2-layer KiCad 7 layout, size 5V/GND paths for ~5A peak, route the DIN/DOUT serpentine path, and validate DRC/fabrication rules. I’ll deliver Gerbers, drill, IPC-356, PnP, BOM and source files. Questions: • Should edge pads carry power and data? • Any preferred pad geometry? PLEASE INITIATE A CHAT I look forward to collaborating with you.

As an electronics engineer with extensive experience across all major EDA tools—including KiCad, Altium, and Eagle—I am fully equipped to deliver this compact 16×20 LED matrix PCB within your strict 64×80 mm footprint and 4 mm pitch requirements. I will meticulously route all 320 WS2812C-2020 LEDs on the top layer while placing the 5V, GND, DIN, and DOUT solder points on the rear side for a clean two-layer stack-up. Leveraging my deep understanding of high-current power distribution, I will design suitably wide traces to handle the ~5A peak load, implement a carefully serpentined data path for seamless edge-to-edge chaining, and apply a robust via/stitching strategy that balances electrical performance with manufacturability at JLCPCB or PCBWAY. While I am equally proficient in Altium and Eagle, I will work natively in KiCad 7 to provide you with complete source files, Gerbers, IPC-356 netlist, pick-and-place data, and a detailed BOM, all with HASL lead-free finish. I will rigorously run DRC and JLCPCB's online pre-check to guarantee the LEDs are perfectly aligned to the grid, ensuring the design is production-ready right out of the box—delivered on time.

Hi, I can design the 320-pixel RGB PCB in KiCad 7 with the LEDs precisely arranged in a 16 × 20 grid at 4 mm pitch. I’ll keep all LEDs on the top layer, place 5 V/GND/DIN/DOUT solder points on the rear, and route the two-layer board with wide power distribution, solid grounding, and a clean serpentine data path for chaining multiple boards. I’ll prepare the complete fabrication package including Gerbers, drill files, IPC-356 net-list, BOM, centroid/PnP data, and the editable KiCad source project. I’ll also verify LED alignment, run DRC, and prepare the design for JLCPCB/PCBWAY manufacturing with lead-free HASL. Question: Do you have an exact board outline, mounting-hole locations, or edge-clearance requirements beyond the approximate 64 × 80 mm size? Best regards
