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
| Platform | Applications |
|---|---|
| STM32 (F0, F1, F4, G0, G4, L4, H7) | Industrial, IoT, control |
| nRF52/53 | BLE, Zigbee, Thread, ultra-low power |
| ESP32 | WiFi, BLE, prototypes, consumer IoT |
| RP2040 | Cost-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:
| Module | Application |
|---|---|
| SoMLabs (preferred) | STM32MP2, industrial, IoT |
| Raspberry Pi CM4 | Linux, multimedia, edge computing |
| Toradex, Variscite | Industrial 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.
Connectivity (IoT & Industrial)
| Type | Technologies |
|---|---|
| Wireless | WiFi, BLE, LoRaWAN, NB-IoT, LTE-M |
| Industrial | Ethernet, CAN, RS485, Modbus |
| Short-range | NFC, RFID, SubGHz |
Power Management
| Area | Scope |
|---|---|
| Power supplies | SMPS (buck, boost, buck-boost), LDO |
| Batteries | Li-Ion/LiPo, charging, BMS |
| Energy Harvesting | Solar, thermoelectric |
| Ultra-low power | Consumption optimization <1µA sleep |

Working system ✅
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)

💰 Pricing
Project Quotation
Price depends on complexity — typical ranges:
| Complexity | Example | Price Range |
|---|---|---|
| Simple | Sensor, simple controller | €1,200 - €2,500 |
| Medium | IoT gateway, industrial controller | €2,500 - €6,000 |
| Advanced | System with SoM, multi-channel | €6,000 - €12,000 |
Prices include design (schematic + PCB). Prototypes, firmware, and certification quoted separately.
What Affects Price?
| Factor | Impact |
|---|---|
| PCB layer count | More layers = higher price |
| Power complexity | Multi-rail, battery management |
| Communication interfaces | More interfaces = more work |
| EMC requirements | Stringent requirements = more iterations |
| BSP firmware | If you need a working system |
