@cpp2048

which Nucleo are you planing to use ? Do you need differentially sensed DC inputs for better accuracy. If you share more details about the use cases, then I could suggest whether it needs specially designed analog section which you couldn't achieve using off the shelf nucleo boards. It all depends on the accuracy requirement and the deployment of the final product. Will design with all 3D models.

@TruongPT

Hi! This is exactly the kind of precision-focused hardware design I enjoy. I’ll create a clean, reliable plug-on board in KiCad that conditions all your input ranges — from 100 V down to millivolt-level signals — and ensures safe, accurate delivery to the STM32 within its 0–3.3 V input limits. Power will be properly regulated from 9–36 V input, with full protection and stable analog references, and I’ll integrate RS-485 TX/RX on a terminal for easy external comms. You’ll get a well-documented schematic, routed two-layer PCB (unless a denser design truly warrants more), Gerbers, BOM, and a short design note outlining everything from input scaling to surge handling. Thanks...

@julianm260

✅✅✅✅✅ Hi there, ✅✅✅✅✅ I took a close look at your requirements, and this is exactly the type of hardware work I handle regularly—precision signal-conditioning, protected analog front-ends, and clean KiCad deliverables ready for fabrication. I’ve designed several plug-on boards for STM32 Nucleo and Discovery platforms, including mixed-signal input modules with similar voltage ranges and protective constraints. Before I begin, I’d like to confirm one point: • For the 0–50 mV channels, do you have a preferred amplifier family or noise specification? I can choose a precision, low-offset part if accuracy is critical. If the scope looks aligned, I can get started right away and keep you updated throughout. Looking forward to building a clean, reliable board you can drop directly onto your Nucleo. Thanks for your time.

@muhannadbukhamse

Hi, I am Mohand, a talented Electrical Engineer with extensive experience in KiCad and STM32 firmware development. I am confident in designing the plug-on input board for your STM32 Nucleo as specified, including conditioning the diverse input signal ranges accurately into the MCU's 0–3.3 V range. My expertise covers embedded systems, PCB layout, power regulation, and signal conditioning, ensuring clean signal integration and robust protection, including reverse-polarity and surge safeguards. I have successfully developed similar boards with regulated power rails from wide DC input ranges and implemented RS-485 half-duplex transceivers interfacing with USART. I will deliver comprehensive KiCad schematic and PCB files, Gerber outputs, BOM, and a detailed design note explaining the input scaling and protection strategies. If any input ranges require special treatment, I am open to early discussion to align on the optimum approach. I look forward to contributing my skills to your project and providing high-quality, production-ready design files

@yaroslavmark

Hi, ✅✅✅ I can handle “STM32 Nucleo Input Board Design.” I am a Full Stack Engineer (PCB Designer & Embedded Engineer) with 10 years of experience, providing precision analog front-end design, power regulation, STM32-based hardware, and industrial signal-conditioning circuits. In my opinion, the most reliable approach is to build a protected analog front end tailored to each input range, combined with a stable 9–36 V power tree feeding clean 5 V/3.3 V rails and a low-noise reference. I’ll also ensure the ±5 V / 0–100 V AC shared node is scaled and filtered so both modes map safely into the STM32’s 0–3.3 V ADC range. I’ve previously designed several industrial I/O boards for STM32 and ESP32 where I handled 0–100 V sensing, millivolt inputs, and RS-485 interfaces, all fully implemented in KiCad on two layers with strong analog performance. A key requirement here is accurate analog scaling with proper protection. That means selecting correct attenuation networks, TVS clamps, and RC filters, then validating all ranges electrically so the MCU always sees safe and predictable levels. ✅ So, I will divide your project into three major steps. 1️⃣ KiCad schematic — analog conditioning, protection, power tree, and RS-485 interface. 2️⃣ PCB layout — two-layer routing with analog/digital separation and clean grounding. 3️⃣ Manufacturing outputs — Gerbers, drill files, PnP, BOM, and a brief design note. I am looking forward to working with you. Best regards. Yaroslav
