I am building a board that needs a compact mixed-signal section dedicated to high-accuracy data conversion. The job is to design the entire ADC/DAC front-end, marrying the sensitive analog path with the supporting digital logic so the output is ready to drop straight onto my main PCB. What I need from you • A complete schematic showing the analog input stage, the chosen ADC and DAC devices, reference circuitry, clocking, and the glue logic that links everything to an MCU or FPGA header. • Component selection with justification, balancing performance, availability, and cost. • Simulations that verify noise, linearity, and timing (SPICE, LTspice, or similar). • A clean, well-annotated PCB layout file (Altium, KiCad, or Eagle—your choice, just tell me up fro...

I need a compact, modular eddy-current device built from the ground up to verify the purity of non-ferrous metals during material research and development. Because the unit will often be carried to mines, scrapyards, and temporary field labs, I’m prioritising a rugged, weather-resistant enclosure, battery operation for a full working day, and quick-swap probes so I can tailor frequency and coil geometry to different sample shapes. Core expectations • A handheld main unit that houses the signal generator, receiver, display, data-logging memory and rechargeable power pack. • Interchangeable probe modules covering the typical kilohertz-to-megahertz range used for non-ferrous purity checks, each probe auto-calibrating on connection. • On-board firmware that shows im...

PCB Layout Engineer Needed – Manual Routing of Existing 4-Layer PCB I am looking for an experienced PCB layout engineer to complete the manual routing of an existing 4-layer PCB for a portable AI-powered scientific field instrument (spectral reflectance analyzer). The schematic, component selection, BOM, and initial PCB placement have already been completed. The objective is to complete the routing and prepare the board for manufacturing. Scope of Work: - Review the existing schematic and PCB placement. - Complete manual routing of all remaining nets. - Optimize power, ground, and return-current paths. - Route GPS/RF, SPI, I²C, UART, USB-C, and LED driver signals following PCB best practices. - Resolve all DRC errors and ensure the board is fully connected. - Preserve the exi...

Preference: • Developers who already have a similar prototype or existing industrial hardware platform that can be customiz...

I need an experienced hardware designer to turn my concept for a six-port, gigabit-speed Ethernet switch into a complete, production-ready design. 3 of 6 channel must deliver up to 70 W of IEEE-compliant PoE, other 3 must deliver up to 20 W and, instead of the usual RJ45 jacks, I want every data-plus-power line brought out on JST-GH connectors. Mechanical requirements • Board must be as smaller as possible with 4 holes M3 at the corners. Electrical highlights • True gigabit switching performance across all six ports, with robust QoS and VLAN support. • 70 W continuous PoE available on 3 of 6 ports, other 3 ports 20 W. • 50V output voltage for POE • Input-voltage capability: 10-26V • Protection for reverse polarity, surge, and hot-swap events is essen...

Refer to the detailed SoW: We need a product/electronics-mechanical designer to develop a simple passive extension adapter for a removable code/calibration chip used in a handheld diagnostic device. The device currently requires the chip to be inserted directly into a small slot. We want to create a male-to-female extension so that one end remains inserted in the device and the original chip can be inserted at the other end of a short cable. We already have a 3D STEP model/mapping of the chip geometry, which will be shared after project allocation. The project includes: Male insert design Female chip receiver design Short cable connection Simple PCB/contact design 3D-printable housing design Prototype fabrication Testing with the device Complete design-file and knowledge transfer Im...

Please refer to the detailed SoW - We need an experienced embedded systems / biomedical hardware consultant to design and develop a compact vitals and body composition acquisition subsystem for integration into an existing diagnostic hardware platform. The system must capture BP, SpO2, PPG-derived respiratory rate, heart rate from PPG/BP, temperature, height, weight, BMI, and body composition values such as body fat %, visceral fat, muscle mass, body water %, bone mass, BMR, metabolic age, and segmental distribution where technically feasible (through bio impedance). The work includes sensor/module selection, hardware architecture, PCB/control board design if required, firmware, Windows/Linux compatible local service/API, local session-wise data handling, calibration workflows, validat...

I'm looking for an experienced hardware developer to assist with my Solar MPPT project, which is currently in development. The specific areas where I need help are: - PCB Layout - Circuit Design - Component Selection Ideal skills and experience: - Strong background in power electronics and solar energy systems - Proficiency in PCB design software - Experience with circuit design and component selection - Ability to work collaboratively and provide detailed documentation Please provide examples of similar projects completed.

I need a compact RC timing network that drives a MOSFET to short-out an NTC after start-up so the circuit acts as an inrush-current limiter only for the first few hundred milliseconds. The system runs from a 110 V DC bus and the load can draw up to 10 A once the bypass closes. Your task is to select suitable parts, calculate the RC values that give a clean, repeatable hand-over, and show how the MOSFET gate is protected against the high dV/dt on the bus. I’d like the work delivered as: • Schematic (PDF or KiCad). • Brief calculation sheet or annotated simulation showing how you arrived at the delay and confirming the inrush profile. • Short parts list with readily available components. I can validate the design on my bench, so please keep the explanation con...

I’m putting together an automotive-grade dashcam that runs on an AI SoC and would like a complete hardware schematic as the next step. The core board has to handle two on-board 1080 p digital cameras via MIPI-CSI while also accepting two additional analog cameras through an external A/D bridge so the system can switch seamlessly between all four views. The SoC must be wired to support real-time object detection, lane detection, collision warning, and driver monitoring / assistance functions; please route all required high-speed, power-management, and memory interfaces accordingly. I already have a rough block diagram, so the focus here is turning that concept into production-ready circuitry with a clean, logically layered design that will pass an automotive EMC review. Delivera...

Project Overview I am developing a commercial automotive telematics device for the Indian market. The product will be used for fleet management, GPS tracking, vehicle diagnostics, driver behavior monitoring, and future FASTag ecosystem integration. This is **NOT** a hobby or Arduino-based project. I require an industrial-grade PCB design that can be manufactured in China through PCBWay, JLCPCB, or a similar PCB assembly service. The final deliverable should be ready for prototype manufacturing and later mass production. I am looking for an experienced hardware engineer or embedded systems engineer who has previously designed automotive telematics devices, GPS trackers, CAN bus products, IoT hardware, or vehicle diagnostic devices. --- # Objective Design one universal hardware platfo...
