PCB Layout Jobs

Project Golden Eagle couples solar, a lithium-ion battery energy storage system and gas-fired reciprocating engines into one behind-the-meter plant that will offset our facility’s demand charges and provide resilient back-up power. The preliminary economic model is complete; what remains is a construction-ready electrical design that folds the three resources into a single, code-compliant package. The generation mix is fixed—solar arrays, BESS and gas engines—as confirmed in our internal feasibility study. I already have detailed equipment specifications, protection philosophies and utility interconnection requirements; these must be reflected verbatim in the drawings and calculations you prepare. Where gaps appear, NEC 2023, IEEE 1547 and local AHJ amendments should gui...

I need a compact Bluetooth mouse engineered from the ground up with four physical buttons, a smooth scroll wheel, and a USB-C port for both charging and optional wired use. Beyond the standard right- and left-click, the two extra buttons have to ship pre-mapped to volume control (up / down or mute / un-mute) yet remain fully re-programmable through companion software or firmware so users can assign any shortcut they like later on. The build should feel as solid as today’s premium portable mice, keep latency low, and work cross-platform without separate drivers. I’m open to Nordic, Cypress, or similar Bluetooth LE chipsets as long as you hit excellent battery life and achieve seamless reconnection after wake-up. USB-C power management and over-the-air firmware update capability...

I need an engineer who can take me from concept to working prototype on a precision electromagnetic sensing instrument aimed squarely at industrial non-destructive testing and material verification. The core job is to design a sensor that reads electrical conductivity with high accuracy on metallic parts, while also giving me phase-shift and signal-amplitude data that I can use for deeper analysis. My ideal workflow looks like this: we agree on the excitation frequency range, coil geometry, and signal-conditioning chain; you model and build the probe; you develop the embedded firmware and a simple desktop interface so I can visualise raw and processed readings in real time. Throughout, please keep calibration and repeatability in mind—stable baselines and traceable test procedures a...

I need a complete PCB design built around the ESP32-C3 and five onboard power MOSFETs. The board will sit inside a medium-sized, handheld consumer-electronics enclosure and run from a regulated mains-derived supply, so careful attention to isolation, creepage, and thermal paths is essential. The circuit will drive five independent high-side or low-side loads (I can adapt to whichever topology is simpler on your end) while giving the ESP32-C3 solid Wi-Fi/BLE antenna performance. GPIO pin mapping, level-shifting, protection, and a clean 3 V3 rail must all be worked into the schematic. Please route with sensible trace widths, keep EMI in check, and leave me a little proto area for future tweaks if space permits. Deliverables • Schematic and well-annotated PCB layout • Gerber, ...

I already have three completed boards built around an ESP32, DS3231 RTC, EM18 RFID module, buzzers and indicator LEDs. The schematics and layouts are all in KiCad and functionally proven, but a handful of physical tweaks are still needed before I send them to fabrication again. What I need you to do in KiCad: • Reroute a few traces . * Reszie PCBs * Mark / update silkscreen text • Widen or narrow specific pads and drills so the joints wet better and hand-soldering is more reliable. • Shift certain through-hole parts and add a couple of extra mounting pads called out in my notes. • Adjust overall board outlines on two of the three PCBs so they seat perfectly in their enclosures. Turn-around is short; if you are comfortable in KiCad this should fit easily into a...
