PCB layout is an intricate and complex process that requires many kinds of technical and engineering knowledge. In the world of PCBs and circuit boards, PCBLayout designers are experts in transforming electrical schematics into physical components that can be manufactured into a circuit board, using best practice techniques and components to ensure ultimately optimal results.
PCB Layout Designers must ensure that wiring features like trace and drill paths, component placements, clearances, tightly packed connections and more are all accurately planned and implemented; This means carefully dodging needless obstacles, such as constraints on the size, type and quantity of components, that could limit functionality or halt overall progress on the circuit board. This can include both automated processes like CAD (Computer Aided Design) software systems for component placement as well as manual valuations to make sure all design aspects are in order.
Overall, a professional PCB Layout Designer will be able to bring your electrical schematic from ideas on paper to physicality; by taking into account your available resources and budget to create boards with proper component placement that adheres best to the project's needs.

I need a surface-mount power-supply board designed for a consumer-electronics product. The board will run directly from 220–260 V AC and must deliver a regulated 144 V DC at 300–350 mA. Reliability is critical, so the design has to meet a 6 kV surge requirement, include both high- and low-voltage protection, and achieve a high power factor. I already know the exact outer dimensions for the PCB and will forward the drawing as soon as we start; everything has to fit inside that footprint. Apart from those limits, component placement is up to you. I’m leaning toward standard FR-4, but I’m open to alternatives if you see a clear advantage. Please supply the complete schematic, PCB layout, Gerber files, an annotated BOM with part numbers available from major distributo...
I’m developing a compact, aluminium-clad SMD PCB that will live directly on mains, so every detail must be right first time. The board sits on 1 mm aluminium with 25 µm copper, accepts 220-260 VAC and has to deliver a rock-solid 144 VDC at 300-350 mA. Power-factor must stay high thanks to a hybrid DOB topology, while the protection network must survive 6 kV surges and automatically cut in on both high- and low-voltage events. Everything must be RoHS-compliant. Because the board ultimately feeds a power-supply module, thermals and creepage/clearance are just as critical as the electrical design. I’m looking for a clean, production-ready package that lets me hand Gerbers straight to my fabricator and have parts placed with confidence. Deliverables • Complete schema...
I am building a battery-powered edge node around the STM32WL (LoRa-E5 module) that must sit in the field for years on a single 5 000 mAh cell. To reach that target I need both the hardware design and the accompanying firmware created with an obsessive focus on nano-amp sleep currents and efficient duty-cycling. Core capabilities • Data logging to internal flash or external EEPROM so records are retained between wake-ups. • LoRa communication only; no Bluetooth or Wi-Fi. The node will periodically wake, send an uplink, accept a downlink if present, and return to deep sleep. • Simple sensor block: one digital interrupt input (e.g., reed switch/pulse counter) plus one digital output that can drive an external load for a short, timed burst. Hardware scope – Compl...

I need a custom-shaped, single-layer printed circuit board produced quickly so I can test the mechanical fit and basic electrical routing for a new product I am developing. The overall board must stay as thin as practical; once we speak I will confirm exact thickness and any stack-up limits from my enclosure, but the goal is to minimise profile without sacrificing manufacturability. Here is what I will supply once we start: • A rough outline drawing and simple netlist showing the required connections • Components and preferred connector locations What I expect from you: • Review of my outline and placement to flag any manufacturability concerns • At least three fabricated prototypes shipped to me for bench testing Please use whichever professional tools you a...
I already have step-by-step build notes for a tactile glove and the preliminary PCB design files. What I now need is practical help getting that board fabricated through PCBWay. Your job is to take my PCB files, carry out any touch-ups they still require—basic DRC fixes, panelisation or drill map tweaks—then upload the finished Gerbers and BOM to PCBWay, configure the order and place it. The glove relies solely on sensors, with pressure sensors and flex sensors called out in the documentation, so please double-check that the footprints and connector pinouts for those parts remain intact throughout your edits. Deliverables I expect: • Cleaned, production-ready Gerber, drill and pick-and-place files • Updated BOM highlighting the pressure and flex sensors used &bull...
I need to replace my old SmartDrive-i2c-P.i.D. driver because of this: where, after several attempts, it is proven that the SmartDrive i2c P.i.D. driver does not run (at maximum motor speed) both motors on my side simultaneously
I’m inviting a handful of practicing hardware engineers or PCB designers to spend about 15 minutes inside my pre-launch web app, PartPilot (). Upload a BOM or punch in a part number, then tell me—straight, no sugar coating—what keeps this from becoming a tool you’d lean on every day. During my own testing, the ability to see stock information across four distributors in one glance feels like the killer feature, but I need fresh eyes. Point out what’s confusing, what’s missing, and what would make you actually pay for Pro. How this works • You must have real-world PCB experience; KiCad users are ideal, though Altium or EasyEDA is fine too. • Reply with a line or two about your experience designing boards or managing component sourcing. No ...

I need a production-ready printed circuit board for a compact consumer-electronics tracker. The board has to combine Bluetooth connectivity for smartphone pairing, GNSS positioning for global location data, a LoRa module for long-range updates, and a 3-axis motion sensor to wake the unit only when it moves. Everything will run from a single rechargeable battery, so careful power budgeting and a low-power microcontroller are essential. Form-factor will be small enough to slip into a key-tag style enclosure, so component height and antenna placement must be considered from the start. I’m flexible on the exact silicon—Nordic, Espressif, STM, Semtech, etc.—as long as you can justify part choice against current draw, cost and global availability. Please take the design from ...
I am building a new solar-hybrid inverter around an Infineon reference design and need an experienced technical advisor who can work with me on-site in Bangalore, part-time, through the entire prototype cycle. Your guidance is required across hardware design, firmware development, hardware fabrication, integration and final testing.

Expect plenty of hands-on lab work—oscilloscopes, power analyzers, thermal cameras, rework stations—plus...
I’m looking for a senior technologist who can sit with my Bangalore-based team and guide us through the full hardware-software stack of our new UAV prototype. The work is hands-on and spans three pillars: hardware design, embedded-software bring-up, and end-to-end integration testing. On the hardware side you’ll dive into sensor integration, power-management architecture, and lightweight frame design, checking schematics in Altium/KiCad, reviewing BOM choices, and helping us close EMI and thermal issues. In parallel, you’ll pair with our firmware engineers to refine drivers, control loops and companion-computer interfaces (C/C++, Python, PX4 or ArduPilot experience is ideal). Finally, you’ll shape and run a systematic integration-test plan—bench, HIL and flig...

I need a complete PCB solution for a BeagleBone-based light pod whose primary purpose is, quite simply, “Lightpod.” The concept is already proven on a breadboard; now I want a production-ready board that consolidates the BeagleBone, LED drivers and all supporting circuitry into a compact, manufacturable form factor. What I expect from you • Schematic capture that respects BeagleBone design guidelines and pin-muxing constraints • Optimised PCB layout compatible with standard four-layer fabrication, mindful of thermal paths for high-current LED channels • Clean, clearly annotated BOM with sourcing that avoids hard-to-find parts • Manufacturing outputs (Gerbers, drill files, assembly drawings) plus original design files so I can iterate later in KiCa...
I need a clean, production-ready multi-layer PCB for a new consumer-electronics device. The board will host an average number of components—nothing exotic—but the layout must still respect typical high-speed, signal-integrity, and power-distribution guidelines so the final product performs reliably and passes EMC tests the first time. You will begin from my preliminary schematic and functional block diagram, refine component selection where needed, then build out the full stack-up and routing. I’m comfortable with Altium Designer, KiCad, or Eagle files, so choose whichever platform lets you work fastest; just note that I will need fully editable source files at hand-off. To keep the process straightforward, here’s what I expect at each stage: • Updated schema...
I’m building a compact embedded platform that runs from a single 12 V supply and I need a purpose-built PCB to act as the system’s brain.

I need a clear, ready-to-build circuit diagram that closes the voltage feedback loop on the DC bus of an off-grid inverter running in the 12 V – 24 V range. The diagram must show how a suitable voltage sensor feeds a microcontroller so the firmware can keep the bus voltage within safe limits and trigger protective actions when it strays. Please size all resistive dividers, isolation devices (if required), and any signal-conditioning stages so the microcontroller’s ADC receives a clean, scalable signal. What I expect from you • Complete schematic, preferably drawn in KiCad or Altium, showing the microcontroller, voltage sensor path, power supply rails, and any filtering or isolation you recommend. • Short bill of materials with part numbers that are actually ...

I want to bring a small, ESP32-powered toy drone from concept to first lift-off. The goal is purely recreational: a fun flyer that can be controlled from a smartphone rather than a conventional RC transmitter. Core functionality must include reliable auto-stabilization so even a beginner can keep the craft level. Here’s what I already have in mind: • Flight controller: ESP32 (your choice of dev-kit or custom PCB) • Sensors: a compact 6-axis IMU such as MPU6050/ICM-20689 for attitude data • Motors & ESCs: typical micro-quadcopter class, but I’m open to your sizing suggestions • Firmware environment: Arduino IDE or ESP-IDF—whichever you can deliver faster and maintainably • Mobile control: a lightweight Android/iOS app communicating via...
I need a matched transmitter-receiver pair built around a 200 kHz carrier that can cover at least 40 m in open air and recognise simple OOK (On-Off Keying) pulses reliably. The intended application is “Radio Frequency RF”, so there is no higher-level protocol to worry about; raw, clean carrier switching will do the job. Everything will be mounted and operated outdoors, so the design must tolerate ambient temperature swings, sunlight and occasional moisture without detuning or loss of sensitivity. Both TX and Rx are separate not transceiver and battery powered with minimum 2 days running time. What I am looking for • Circuit-level design of both the low-power transmitter and the super-regen/ super-het (designer’s choice) receiver, including complete schematics, PCB...
I need a compact, self-contained light show for a fan that will be used purely for entertainment. The blades already have addressable LEDs installed; what’s missing is an eye-catching sequence of color-changing effects and the code or controller setup that drives them. Here’s what I’d like from you: • Design several smooth, vivid color-changing patterns that look great while the fan is spinning. • Provide the controller code (Arduino, ESP32, Raspberry Pi Pico, or any platform you prefer) together with a clear wiring diagram so I can replicate the exact results on my unit. • Include simple instructions for adjusting speed, brightness, and palette so I can fine-tune the mood for different occasions.
