From Concept to Prototype—Built for Function, Ready for Production
From Concept to Prototype—Built for Function, Ready for Production
At ProtoLab, we specialize in the design and development of custom electronic devices—from idea to fully functional prototype. Whether you’re building an EVSE controller, industrial gateway, sensor node, or vending telemetry module, we deliver complete, integrated hardware solutions tailored to your specific requirements.
As a compact engineering bureau, we focus on speed, flexibility, and quality. Our design process bridges electronics, firmware, mechanical integration, and user interaction—giving you a real, testable device that’s ready for the next step.
What Is Device Design?
What Is Device Design?
Device design is the full-stack process of creating an electronic product—from its internal circuits and embedded logic to its physical enclosure and user interface. At ProtoLab, device design includes:
Requirements definition and block diagram architecture
Component selection and schematic capture
PCB layout, validation, and review
Embedded firmware design
Connectivity (RS485, CAN, Ethernet, Wi-Fi, etc.)
Enclosure and mechanical integration
Prototype build and functional validation
Our strength lies in bridging the gap between concept and hardware—especially when it comes to low-to-medium complexity devices used in energy, automation, IoT, and industrial environments.
Why Clients Choose ProtoLab
Why Clients Choose ProtoLab
Many of our clients are startups, product teams, or OEMs who need:
A working prototype built quickly for testing or pilot deployment
Help defining a realistic technical scope for a custom product
A design that’s ready to scale into small-batch production
Localized support for Moldovan or EU-based clients with tight integration needs
Flexibility across communication protocols, power domains, or form factors
With ProtoLab, you don’t need a 10-person engineering team. You get a lean, focused group that designs, builds, and tests hardware that works.
Our Device Design Workflow
Our Device Design Workflow
🧩 1. Architecture & Requirements
🧩 1. Architecture & Requirements
We begin by understanding:
Intended use cases and operating environment
Key electrical, communication, and physical constraints
User interface or display needs
Certification or safety requirements
We then produce a block diagram and design strategy that clearly defines how the device will work.
🔌 2. Schematic & PCB Design
🔌 2. Schematic & PCB Design
Once the architecture is defined, we move to detailed design:
Component selection (cost, availability, certification)
Schematic capture and library management
Power distribution and signal integrity planning
PCB layout with design-for-manufacturing (DFM) focus
Review and validation with your team
Designs are delivered with Gerber files, BOMs, and 3D models, ready for prototyping or production.
🧠 3. Embedded Firmware
🧠 3. Embedded Firmware
We also handle embedded software development:
Microcontroller initialization and driver integration
Communication stacks (Modbus, MQTT, HTTP, CAN, etc.)
State machines, logic control, timing functions
Power-saving modes and fault handling
Real-time monitoring, ADC/DAC, and peripheral integration
Our firmware is written to be portable, testable, and production-ready.
📦 4. Enclosure and Mechanical Integration
📦 4. Enclosure and Mechanical Integration
Device design doesn’t stop at the PCB. We ensure:
Board fits with buttons, connectors, and displays
Enclosure provides proper thermal dissipation and sealing
Mounting methods suit the deployment (DIN rail, panel, wall, handheld)
Prototypes are physically robust and client-demo ready
We support 3D printing, laser-cut acrylic, and CNC machining through in-house tooling or trusted partners.
🧪 5. Testing and Iteration
🧪 5. Testing and Iteration
Each device is tested for:
Power-up behavior
Functionality of each I/O or feature
Interface behavior (UI/UX logic)
Electrical safety and EMI behavior (pre-compliance)
Environmental and mechanical fit (enclosure-level)
We work in fast iteration cycles, enabling agile development of even complex hardware.
