Layout PCB Jobs

I have a CAN-based hardware concept for trucks and excavators that still needs an expert eye and solid firmware. The board carries a CAN transceiver plus an as-yet-undecided microcontroller; your first job will be to review the schematic and component choices, making sure the design can reliably tap into a heavy-vehicle J1939 network. Once the electronics check out, I need production-ready code that listens for multiple PGNs, performs light, on-board processing, and then forwards all remaining data to my back-end through a Bluetooth link. On the edge we have to handle three record types: sensor readings, diagnostic trouble codes, and operational parameters. Any PGN we do not actively process must be packed efficiently and shipped over Bluetooth for cloud processing, so memory management a...

I need a complete engineering package for a fully-automated, single-ram stationary compactor that serves municipal transfer stations across Libya and North Africa. The unit must accept waste straight from collection trucks, guide it through a hydraulic tipping device into a hopper, then compress it into a detachable hook-lift container. Two identical containers will work in rotation so the site can keep running while one is being hauled away. Key performance and build notes • Continuous duty cycle with twin, interchangeable containers • Conventional steel fabrication only, using processes commonly available in Tunisia and Libya (no exotic alloys or proprietary castings) • Robust automation: PLC-controlled sequencing of tipping, ramming and container exchange • ...

I need a purpose-built PCB for an APAS control system that will ultimately drive a small embedded platform. The board must be laid out on two copper layers and should balance tight signal integrity with compact mechanical footprints, as space inside the enclosure is limited. You’ll start from a functional block diagram and a rough schematic I already have on paper. Component selection is mostly open, so feel free to optimise around availability and cost. I’m comfortable with Altium Designer, Eagle, or KiCad, so use whichever environment lets you work fastest; I only ask for the native files along with the usual production outputs. Deliverables • Cleaned-up schematic ready for review • Final two-layer through hole PCB layout (230 mm × 130 mm target size) ...

The job is to turn a very small, single-sided board—35 mm × 23 mm, 1.5 mm thick—into a full Gerber package ready for fabrication. The layout is straightforward: one reed switch, a single copper track, and two solder lugs. You will work from the material I already have: clear photographs of the prototype and a dimensioned PDF that came out of my AutoCAD workflow. No special manufacturer or industry rule set is required; just follow standard defaults that any board house can accept. Deliverables I need back: • RS-274X Gerber files for all layers (copper, solder-mask if used, silkscreen if needed, and board outline). • Excellon drill file. • A quick read-me confirming layer naming and the units you used. Once I receive those files, I should be able to u...

I have several single-layer printed circuit board that has stopped performing reliably. Several symptoms point to multiple underlying faults: a few components no longer behave as expected, some traces appear open or damaged, and certain connectors intermittently lose continuity. Unfortunately, I do not have the original schematic or any Gerber/design files, so the job will require hands-on troubleshooting and a bit of reverse-engineering. Here’s what I need from you: • Locate and replace or re-solder the malfunctioning components. • Identify and restore any broken or lifted traces so every signal path is solid. • Resolve the intermittent connection issues at the board’s headers and edge connectors. • Once the board is fully functional again, capture ...

I already have a complete STEP-format CAD model of my foot massage device and have sourced the key parts I’d like to use inside it. What I still need is a skilled electrical engineer who can turn that mechanical shell into a working MVP that we can put in front of early testers. Core features to implement • Adjustable pressure driven by a compact motor system • Consistent, safe heat therapy integrated into the same housing Scope of work You will review my CAD, confirm that the components I’ve chosen truly fit the envelope, then design and build the electrical architecture that powers both features. This includes creating the schematics, selecting any supporting parts I may have missed (drivers, temperature controllers, safety fuses, wiring gauges, connectors), and...

I have completed the schematic and multilayer PCB layout for a custom GNSS / GPS module that will sit inside a small-form-factor UAV. Before I press the “order” button, I need a second set of expert eyes to validate every critical detail, with extra attention on the power-supply architecture—which I flagged as my primary concern. The review should cover GNSS/RF trace routing, impedance control, grounding strategy, EMI/EMC risk points, component placement for manufacturability, and overall reliability under airborne vibration and temperature swings. If you spot an issue, I expect you to offer (and, if we agree, implement) concrete fixes so the board comes back right the first time. Design files are proprietary; I will share the Altium project after I see examples of ...

I already have a complete schematic for a multi-function meter built around the STM32H743BIT6. Before I move to PCB layout I need a fresh set of eyes to refine the design, swap a few key parts, and fold in two new capabilities. Work required • Correct any schematic errors you spot (net ties, pin assignments, power flags, ERC issues). • Replace the specified parts—new values for several resistors and capacitors plus an updated pin-compatible MCU revision. • Add extra sensing channels and tighten the power-management section so the board runs cooler and meets my standby-current target. • Schematic circuit diagram design and PCB Design in Altium software. We may provide Altium software. • Simulation required in Proteus software. We may provide software. &...
