PCB Design and Layout Jobs

I want an HID Omnikey 3021 smart-card reader—converted so it connects through a standard USB-C port instead of USB-A, while still providing full-speed data communication and bus power. I only need the cable/connector side removed and replaced with a USB-C connector so the device enumerates and draws power over USB-C just as reliably as it does over USB-A. There should be no cable, just a USB-C connector so that the device is as small as possible. Here is what will make the job a success: • The finished reader plugs into any standard USB-C host and both powers up and transfers smart-card data without errors. • All USB-C wiring follows the spec’s pin-out and current-handling guidelines. • You supply clear documentation (schematic or wiring map, parts used and...

We are seeking an experienced PCB designer to review, correct, and optimize an existing PCB design and provide the layout file with the dxf format Project Scope: * PCB includes ESP32 (or MCU), USB interface, and RS485 communication * Existing schematic is already completed in EasyEDA (there are some issues) Tasks: * Review and validate schematic (identify gaps/issues) * Optimize power design and signal integrity. * Perform professional PCB layout design. * Ensure EMI/EMC considerations and stable communication (USB + RS485) * Prepare production-ready files (Gerber, BOM, Pick & Place) Requirements: * Must work in EasyEDA (collaborative mode) * Strong experience with mixed-signal PCB, communication interfaces, and power optimization. * Ability to identify design flaws and improve reli...

I’m building a compact, two-layer PCB in Altium Designer for the back-light circuit of a bus. The schematic is roughly sketched, component choices are clear, and now I need an experienced board designer to turn the concept into a production-ready layout that can survive the automotive environment (vibration, temperature swings, noise). The job covers refining the schematic where needed, arranging the components for optimal thermal flow and EMC performance, routing the board within the mechanical outline I will supply, and running all Altium DRC checks until the file is clean. Once we are happy with the layout, I also want standard fabrication outputs so I can send the job straight to the board house. Deliverables • Altium project (schematic & PCB files) • Gerbers,...

I need a complete engineering solution for an ultra-low-frequency electromagnetic transmitter that operates at roughly 22 Hz and fits inside an inline pipeline PIG. Once the PIG is in service, the beacon’s field must be strong enough to be detected up 3–5 m above the pipe, even when the signal has to pass through steel wall, backfill, soil, and asphalt or reinforced concrete. All operations take place underground and fully enclosed by steel, so coil geometry, core selection, drive strategy, and noise rejection are critical. Scope of Work: • Design a low-frequency (~15–30 Hz, target 22 Hz) EM transmitter • Optimize signal strength for underground detection • Develop efficient antenna/coil design suitable for pipeline use • Design low-power circuitry fo...

Design a complete electronic schematic for our smart orthotic insole device based on the given system requirements. The circuit will include multiple FSR sensors (Force Sensitive Resistors) for plantar pressure sensing and an IMU sensor for gait/motion tracking. Select and integrate suitable supporting components such as microcontroller, BLE communication module, power management circuit, battery charging unit, connectors, and signal conditioning circuits. Ensure proper sensor interfacing, analog signal acquisition, filtering, and calibration provisions in the schematic design. After schematic approval, develop a compact, optimized PCB layout suitable for wearable insole integration with size and flexibility constraints in mind. PCB must be designed for low power consumption, stable sensor...

I’m outfitting an ArduCopter that runs 6-cell Li-ion packs and need a purpose-built Battery Management System. The board and firmware must continuously monitor pack health, actively balance the cells and speak Mavlink over CAN so the flight controller sees accurate live data. Core functions • Real-time battery monitoring with voltage, current and temperature reporting for every cell and for the full pack • Automatic cell-to-cell balancing to maximise capacity and cycle life • Safety layer that disconnects or limits power on over-charge, over-discharge or short-circuit events • Mavlink-over-CAN telemetry, using the standard ArduCopter battery status messages so Mission Planner and QGroundControl display everything without custom plugins What I expect as d...

I need a complete electronic design for a next-generation health-monitoring smartwatch whose signature element is a high-resolution micro camera mounted flush to the wrist side of the case. That camera will analyse the wearer’s skin to extract deeper, image-based health insights beyond the usual heart-rate and SpO₂ readings. I am open to your proposals on exactly which metrics image processing can reveal, provided they are scientifically sound and can be handled by an embedded processor in real time. Core hardware requirements • High-resolution skin-facing camera, paired with a wearable-class microprocessor powerful enough to process or compress the image stream on-device. • Minimum 16 GB on-board storage for captured data. • Bluetooth for data sync, a vibrant T...
