We build the whole electronic system, from silicon to cloud
Bare-metal firmware and embedded Linux, high-speed PCB layout, mechanical and thermal, SMT manufacturing, through to backend and cloud — all in one team. We do project-based R&D for high-reliability systems; we don't sell off-the-shelf products.
One team that owns the whole system — not an integrator, not a product vendor
Unlike large-scale integrators or off-the-shelf product vendors, Spark Labs builds custom from scratch for each problem: firmware, hardware, mechanical, manufacturing and software all sit inside one team. Clients pay no 'coordination tax' across vendors and face no hand-off gaps between stages. We engage through a long-term R&D partnership model.
Why clients choose Spark Labs
Customizable down to the register
We own hardware and firmware down to NVIC/MPU configuration, register-level programming, and writing our own drivers, BSP and Device Tree — not assembling from closed libraries. We can reach as deep as the problem requires.
One team, silicon to cloud
Bare-metal, Linux kernel, high-speed PCB, mechanical and thermal, SMT manufacturing, backend/cloud — one group. No hand-off gaps, no dependence on multiple vendors.
In-house manufacturing
Hands-on SMT line operation, quality control and supply-chain management — rare for an engineering studio. We can carry a design all the way from R&D prototype to mass production.
Small-team speed
A small team, no bureaucracy, direct technical decisions. AI-assisted workflows make us faster — but every output is verified by a qualified engineer.
Absolute transparency
We state our capabilities, limits and risks clearly — including what we haven't done. No fabricated specs, no spin. Engineering errors from inaccurate information are unacceptable to us.
From silicon to cloud
Multi-disciplinary engineering capability for complete electronic products.
Embedded Firmware Engineering
Firmware across many MCU families, from bare-metal and RTOS to embedded Linux — mastered down to the register, not just library calls.
Embedded Linux & BSP
Deep embedded Linux capability, from bootloader to kernel — a rare skill set in the Vietnamese market.
Hardware Design & High-Speed Digital
Schematic and PCB layout for mixed-signal, RF and high-speed digital — designed so it can be measured and verified.
Wireless Mesh Communications
A core strength: multi-node mesh that self-forms, self-heals and tolerates faults — including time-synchronized mesh for deterministic communication.
Vehicle Electronics & Automotive
ECU and CAN network design for motorcycles and cars — automotive-grade reliability under real operating conditions.
Mechanical & Enclosure Design
Mechanical tied to electronics — from PCB to a complete ruggedized enclosure, with thermal simulation.
Engineering depth, verified
Three rare capabilities that demonstrate genuine engineering depth.
ARM Cortex-M mastery, down to the register
Thumb-2 and single-cycle execution optimization, NVIC tuning for deterministic interrupt latency, MPU for safety/security, register-level SysTick/DMA programming, JTAG/SWD debug with breakpoints/watchpoints. Across Cortex-M0/M3/M4/M7 on STM32, SAM, nRF, ESP32.
Embedded Linux from bootloader to kernel
Kernel configuration and porting for custom hardware, device drivers (char/platform, I2C/SPI/UART/USB, network), BSP bring-up, U-Boot porting, Device Tree (DTS/DTB) authoring, custom distros with Yocto/Buildroot, kernel debug with kgdb/ftrace/JTAG. A rare skill set in this market.
High-speed digital — and measured
10 Gigabit Ethernet (XFI/SFI), multi-gigabit SerDes lane routing, SFP+/SFP integration, controlled impedance, length/skew matching, power-integrity (PDN) design. Above all: we measure and verify it with eye diagrams and jitter analysis on real oscilloscopes and analyzers.
Engineering rigor on every project
Six principles across every project — and one commitment: we don't design to 'run once', but for mass-production durability.
Accuracy First
We never fabricate specs, datasheets or technical conclusions. When something is uncertain, we state the degree, explain the assumptions, and propose how to verify.
Research Before Answering
Analyze thoroughly, verify assumptions, compare options and weigh trade-offs before recommending — no generic, surface-level solutions.
Engineering Mindset
Design for reliability, maintainability, scalability, safety and manufacturability — stable enough for real production, not just to "run once".
Grounded in Reality
Products must run in harsh conditions: vibration, shock, heat, unstable power, electrical noise, intermittent connectivity, and limited MCU resources.
Structured Thinking
Trace the root cause, state assumptions and constraints, compare options with trade-offs, then justify the choice and anticipate risks and edge cases.
AI-Native Engineering
We bring AI into the workflow methodically to work faster and better — but every output is verified by a qualified engineer.
To us, engineering errors caused by inaccurate information are unacceptable — especially in safety-critical systems. When something is still uncertain, we state the degree plainly, explain our assumptions and propose how to verify, instead of giving an answer that merely sounds good.
Transferable engineering experience for mission-critical systems
Harsh-environment design, long-term reliability, trusted supply chain, secure communication and wireless mesh — building blocks tied directly to defense and security systems.
