Cost-conscious engineering
Validate important decisions early and reduce avoidable board spins, rework, and integration cost.
Ideas, engineered into real hardware.
We help early-stage startups, innovators, and researchers turn deep-tech ideas into products that work in the real world, with hardware, firmware, mechanics, and software built together.
5+ years
Building hardware since 2021
End-to-end
From concept to tested hardware
Global
Clients worldwide
6 disciplines
One engineering team
We engineer the difficult parts.
From the first technical concept to a functional prototype, Spezar brings together the disciplines required to turn an idea into a real, testable product.
- 01
Electronics & PCB
Schematic design, multi-layer and high-speed PCB layout, power electronics, sensor and RF interfacing, and hardware bring-up and testing under real load.
- 02
Embedded Systems
Firmware for STM32, ESP32, nRF and similar MCUs in C/C++, bare-metal or FreeRTOS, with drivers, bootloaders, OTA updates and low-power design.
- 03
IoT & Connected Systems
LoRaWAN, BLE, Wi-Fi and cellular connectivity, gateway design, MQTT and cloud integration, and telemetry that stays reliable in the field.
- 04
Robotics & Automation
Mobile robots and AGVs, robotic arms and custom robotic systems, BLDC, stepper and servo motor control, navigation and sensor fusion, and PLC and machine automation.
- 05
Mechanical & Product Design
3D CAD and industrial design, enclosures with IP-rated sealing, thermal and structural analysis, and design for manufacturing from the first revision.
- 06
Prototyping & Manufacturing
3D printing, CNC machining, laser cutting, PCB manufacturing and assembly, bench testing, and small-batch production support.
- 07
AI & Intelligent Systems
Computer vision and TinyML on edge devices, sensor signal processing, anomaly detection, and models tuned to run within embedded power and memory limits.
- 08
Software & Cloud
Web apps and real-time dashboards, mobile and desktop apps, backend APIs and device management, OTA update infrastructure, and cloud integration.
From idea to engineered product.
Hardware mistakes get expensive the later they're found. Our six-stage process tackles the risky decisions early, so every step builds on something already tested.
Ideas become tested hardware, one stage at a time.
- 01
Idea
We dig into the problem, the users and the environment, then turn it into clear technical requirements, including any standards the product must meet.
- Requirements
- Feasibility check
- 02
Concept
System architecture, key component choices and an early BOM, plus a wired proof-of-concept on dev boards to prove the core idea before any custom design.
- System architecture
- Wired prototype
- Concept design
- 03
Design
Industrial design, schematics and PCB layout, 3D CAD and enclosure design, firmware, and the software and cloud pieces, all designed together.
- Industrial design
- Electronic design
- Mechanical design
- Firmware development
- Software & cloud
- 04
Prototype
PCB fabrication and assembly, 3D-printed and machined parts, and first bring-up on the bench to get a working device in hand quickly.
- PCB assembly
- 3D printing
- Bench bring-up
- 05
Validation
Functional, thermal and power testing, EMC pre-compliance and field trials, with product design iterations until it's ready for release.
- Functional testing
- Field trials
- Design iterations
- 06
Product
Design for manufacturing, production files and assembly guides, test fixtures, and support through pilot runs into volume production.
- PCB manufacturing
- Machining & laser cutting
- Production support
The right tools for every layer.
From embedded hardware to cloud-connected products, our teams work across a carefully selected technology stack.
Hardware & embedded
Platforms and tools for electronics, connectivity, and edge devices.
Software & cloud
Tools for connected products, applications, and data services.
More than a working prototype.
Hardware, firmware, mechanics, and software are built by one connected team, so interfaces don't break between agencies and your product moves forward with confidence.
- No friction between PCB dimensions and enclosure tolerances
- Firmware developers sit right next to hardware bring-up benches
- Continuous testing at each iteration prevents costly re-spins
One connected team
Electronics, firmware, mechanics, and software are designed together around the same product goals.
Ready to scale
Build a dependable foundation that can grow from a working prototype to a production-ready system.
Fewer handoff gaps
Keep requirements, design choices, and validation connected across disciplines and project milestones.
A partner through delivery
Work directly with the engineering team through prototyping, testing, refinement, and technical handover.
Expertise across verticals.
From agriculture and healthcare to industrial automation and consumer products, we bring the same engineering depth to every sector we work in.
Consumer IoT
Connected home devices, wearables, and everyday products.
MedTech
Diagnostic devices, biometric sensors, and patient monitoring.
Oil & Gas
Rugged telemetry for remote and demanding infrastructure.
Energy & Utilities
Metering, renewables, and real-time grid monitoring.
Smart Agriculture
Field sensing, solar gateways, and automated irrigation.
Industrial Systems
Machine connectivity, automation, and production testing.
Remote Solutions
Autonomous monitoring beyond reliable network coverage.
Assistive Tech
Adaptive electronics for mobility, haptics, and daily living.
