PCB Design & IoT Hardware
SDI designs production-ready printed circuit boards and connected hardware platforms — from architecture and schematic capture through layout, bring-up, and factory release.
Whether you need a sensor node, gateway, edge controller, or full IoT product stack, our engineering team unites electronics, embedded software, and manufacturing discipline under one program.
Hardware Strategy
Real-world IoT products fail when schematic choices, RF layout, power architecture, and firmware assumptions are made in isolation. SDI coordinates every layer — electrical, mechanical, thermal, and software — before the first spin.
Our multidisciplinary approach de-risks BOM cost, certification paths, and factory testability early, so your platform scales from pilot builds to volume without redesign cycles.

Common questions about PCB design, IoT hardware, timelines, and production handoff.
What PCB design services does SDI provide?
Architecture, schematic capture, multi-layer layout, SI/PI review, prototype coordination, and factory-ready Gerber releases.
Do you design IoT devices with wireless connectivity?
Yes. We integrate Wi-Fi, Bluetooth, LoRa, cellular, Thread, Matter, and other protocols with antenna and certification planning.
Can you work from an existing schematic or layout?
We audit and improve existing designs for cost, reliability, manufacturability, and firmware compatibility.
Do you handle firmware alongside PCB design?
Yes. Embedded bring-up, drivers, RTOS, and communication stacks are part of our hardware programs.
What MCUs and processors do you support?
ESP32, nRF52, STM32, NXP i.MX, Raspberry Pi compute modules, TI, Microchip, and Qualcomm platforms among others.
How do you approach sensor integration?
Signal conditioning, calibration, fusion algorithms, and mechanical placement coordinated with industrial design.
Do you support edge AI on device?
We implement edge inference pipelines on capable MCUs and companion processors with cloud fallback.
What is included in a factory handoff package?
Gerbers, assembly drawings, BOM, test procedures, firmware images, and vendor communication support.
How long does a typical PCB + firmware program take?
First-spin hardware often ships in 8–14 weeks depending on complexity, RF requirements, and certification scope.
