Device architecture

Custom embedded hardware design

Architecture and prototype design for embedded systems that combine MCUs, sensors, power, wiring, enclosures, connectivity, and firmware.

Use this when a product or internal tool needs a practical hardware plan before PCB layout, manufacturing, or vendor handoff.

Typical scope

  • MCU/module selection, sensor suite design, wiring architecture, enclosure constraints, BOM notes, and bring-up plan
  • ESP32, PIC, Atmel, STM32-style MCUs, Raspberry Pi or embedded Linux companions, Wi-Fi, BLE, UART, I2C, SPI, MQTT, OTA notes, and cloud APIs
  • Readable documentation so PCB designers, installers, manufacturers, or internal engineers can continue safely

Questions this page answers

Do you do PCB layout?

I can handle architecture, review, prototypes, and vendor-ready specs. Larger PCB layout or certified product work can be coordinated with specialists.

Can you improve an existing prototype?

Yes. Existing boards, dev kits, messy wiring, and partial firmware are common starting points.

Next step

Send a small brief.

Include the board, sensors, machine interface, current failure, desired behavior, connectivity, dashboard or alert needs, and the artifact you need: IoT prototype, working firmware, data bridge, control box, edge AI workflow, OTA/telemetry plan, or vendor handoff packet.
