From concept to production: schematics, multilayer layouts, embedded firmware, EMC pre-compliance support. For certified medical devices and precision instrumentation.
We join the project from the concept stage: together with the client we define architecture, regulatory constraints, platform choices and certification roadmap. We do this because we know that every early decision shapes what happens 18 months later in audit.
We develop schematics and multilayer PCB layouts, from the simplest configurations up to complex stack-ups with controlled impedance and HDI microvia technologies.
From 8-bit MCUs (HC08, PIC, AVR) to 32-bit ARM, RISC-V and DSP architectures, we develop firmware in C, C++ and assembly. We choose bare-metal or an RTOS (FreeRTOS, Zephyr) based on real-time, footprint and application-complexity constraints.
Spectrum analyzer, current and differential probes, wide-band oscilloscopes, logic analyzer. We identify and mitigate EMC issues during development, reducing pre-compliance cycles at accredited laboratories. We do not substitute accredited EMC labs for final compliance.
Hardware bring-up and firmware debugging with JTAG/SWD, logic analyzer, low-level signal analysis. Functional validation, driver integration, stress testing in realistic conditions before release.
Development compliant with MDR, IEC 60601, IEC 61010, producing the technical documentation supporting CE-marking dossiers, FDA 510(k) submissions and ISO 13485 quality systems. Our internal DMS/QMS (Alfresco + OpenProject + Wiki.js) can be made available to the client for regulatory submissions.
3D Front-end for four-channel IEPE piezoelectric sensors, sampled simultaneously — the condition for reading a triaxial accelerometer without shifting the axes. 24-bit conversion over 20 kHz of bandwidth, up to 400 kSPS per channel, ±10 V AC input with 3.5 mA excitation and a non-isolated boost on board. It detects cable break and sensor short circuit.

PCB layout, rapid prototypes via EU PCB house
Drivers, integration test, validation
EMC debugging, documentation, support to external compliance labs
Production documentation, versioned Gerber/BOM/CPL files, pre-production prototype validation, support for production setup at the EMS chosen by the client or coordinated by us on request.
Real client work produces open-source tools we publish so other engineers can use them. They are demonstrative — not a substitute for compliance tools — but they embody our approach to engineering computation.
Load the Gerber + drill files of a PCB (multi-file or .zip) and view the composed layers, with pours and clearances rendered correctly.
Decode and build USB-PD Power Data Objects: paste the hex PDOs to read voltages, currents and PPS/EPR profiles — or generate the PDO from values, ready for firmware.
