Electronics Design (PCB)

Comprehensive embedded systems design — from schematic to working prototype. Unique combination of hardware and software competencies.

Service Details

  • MCU Specialization : 32-bit ARM Cortex-M
  • Main Platforms : STM32, nRF52/53, ESP32
  • IoT Connectivity : WiFi, BLE, LoRaWAN, NB-IoT
  • Power : SMPS, LDO, Li-Ion BMS
  • Tool : KiCad (open source)

🎯 Need Electronics Design?

Typical challenges I help with:

  • Prototype on Arduino/devkit — Time to move to a production board
  • EMC problems — Device fails certification tests
  • HW/SW integration — Hardware works, firmware works, together they don’t
  • Cost optimization — BOM too expensive for mass production
  • Battery life — Device drains battery in hours
  • Missing competencies — Software team needs hardware support

My key advantage: I combine Hardware (PCB) and Software (Firmware) engineering competencies. You get not just a board design, but an integrated, working system.


💪 My Specializations

Microcontroller Systems

PlatformApplications
STM32 (F0, F1, F4, G0, G4, L4, H7)Industrial, IoT, control
nRF52/53BLE, Zigbee, Thread, ultra-low power
ESP32WiFi, BLE, prototypes, consumer IoT
RP2040Cost-sensitive applications

System-on-Module (SoM) Integration

For projects requiring Embedded Linux, I use pre-certified SoM modules. This approach significantly simplifies CE certification, accelerates Time-to-Market, and reduces costs and risks associated with designing high-speed buses (DDR, USB3, PCIe).

I design carrier boards for computing modules:

ModuleApplication
SoMLabs (preferred)STM32MP2, industrial, IoT
Raspberry Pi CM4Linux, multimedia, edge computing
Toradex, VarisciteIndustrial applications

Benefit: Faster deployment, lower risk and project costs. A SoM module is a tested, certified system — you get reliable hardware without paying for complex DDR, USB3, PCIe interface design.

⚡ Why HW + SW Integration Matters

Typical problem: Silos

      "Together it DOESN'T work" 😱

My approach: Integration from the start

Result: Drastically shorter Time-to-Market and no “ping-pong” between teams.


📋 Work Standards

Design for Certification (DfC)

Designs created with CE certification and RED directive in mind:

  • ✅ Proper ground and power plane routing
  • ✅ Power filtering and signal separation
  • ✅ Pre-certified radio modules (where possible)
  • ✅ EMI/EMC risk minimization

Design for Manufacturing (DfM)

Designs ready for mass production:

  • ✅ IPC standards for footprints and pads
  • ✅ Panelization and fiducial markers
  • ✅ Test points for ICT/FCT
  • ✅ BOM optimization for component availability

Full Transparency (KiCad)

All designs delivered in open KiCad format:
