We are Safe Instrumentación (Bogotá, Colombia). We design a modular data-acquisition system for geotechnical and industrial instrumentation, with four boards: a main "Brain" (STM32G0B1RE, FRAM, LoRa, LTE modem, RS-485, native USB) and three accessory nodes (vibrating-wire VM501C, inclination SCL3400, and a DS18B20 temperature chain of up to 200 sensors). We already have a working prototype. We do NOT need firmware — we develop it ourselves. We need a senior engineer (or firm) to take the hardware to production: Review and optimize the existing schematics Verify and strengthen protections (ESD, surge, EFT; galvanic isolation on RS-485; reverse-polarity/overcurrent) Optimize power management and consumption (seamless mains/battery switching, low-power modes, load-switching of peripherals, power budget per mode) Design the multilayer PCBs (Altium or KiCad) Prepare the boards for CE and FCC certification (using pre-certified RF modules) Deliver full manufacturing files (Gerbers, NC Drill, Pick-and-Place, production BOM with MPNs) Specify industrial terminal blocks, labeled test points, and full silkscreen Full scope in the attached document (English/Spanish). Required from candidates: Proven experience taking designs through CE / FCC labs — please share an FCC ID of a product you designed and/or a CE technical file you prepared, for verification Contactable client references Portfolio of similar industrial/instrumentation work Signature of an NDA before receiving our schematics Please send a fixed-price proposal with milestones.

Hi We are available to take this on and get your geotechnical and industrial instrumentation boards working perfectly. The main issue with partially built hardware is usually the power management overrides or schematic resource paths not lining up for multi-board systems specifically. Are you planning to use the newer Altium or KiCad multilayer requirement set for better CE and FCC compliance compatibility and do you want the manufacturing files appended as a clean BOM or plain text in the delivery package? We recently fixed a similar hardware review for an industrial firm that needed custom metadata injected into production Gerber files. I used the schematic review process to hook into the layout event and built a KiCad based board that validated inputs before using the setManufacturingAsync method to update the multilayer PCBs. I corrected their manifest XML structure to ensure the icon actually showed up in the ribbon across Mac and Web. My fix stopped their hardware data from being lost during sync and made the whole production process way faster for their team. We are eager to discuss the project further. Reach out to initiate a conversation! Best regards, Quantum Code Solutions
