Micro-ElementsCustom electronics & software
Why us

Custom projects, for companies of every size.

Custom engineering and production are what we have done all our working life. Start-ups, manufacturers and large companies alike need devices that simply aren't on the shelf — a controller for a machine, a gateway for a fleet of inverters, a sensor that sees what others miss. Whatever the size of your company or of your project, you get a dedicated team that builds exactly what you need. One team designs the hardware and writes the software, so nothing gets lost between suppliers.

  • 01
    One point of contact, idea to production

    The same engineers draw the schematic, write the firmware, build the server and the app — and answer your call afterwards.

  • 02
    Hardware and software designed together

    The board is designed for the software it will run, and the software knows the board. Fewer surprises, faster debugging.

  • 03
    From the first prototype to series production

    Boards designed for automated assembly, production test stations, programming tools, serial-number labels and test records for every unit.

  • 04
    Built to keep running

    Watchdogs, safe fallback states, remote firmware updates and monitoring — devices that recover on their own in the field.

What we do

Anything in electronics. And the software around it.

A selection of what we design, build and run every day. Need something that isn't listed here? Ask us — custom work is what we do.

Electronics & PCB design

Schematics and multilayer layouts: mixed-signal, galvanically isolated interfaces, Power over Ethernet, mains-powered and battery designs — ready for automated assembly.

IsolationPoE230 VLow powerDFM

Embedded firmware

ESP32 (S3, P4), STM32 down to bare-metal register level, Microchip PIC 8/16/32-bit. Over-the-air updates, signed firmware, watchdog recovery, production test modes.

ESP32STM32PICC / C++OTA

Industrial connectivity

Fieldbuses and networks that talk to the equipment you already own — meters, inverters, PLCs, sensors and the cloud.

Modbus RTU/TCPCANRS-485MQTT / TLSSNMPLoRa 868BLEUWBwM-Bus

Edge AI & machine learning

Neural networks trained on raw sensor signals and squeezed to run on the microcontroller itself — classifiers of a few kilobytes that decide on the device, without the cloud.

CNNINT8TinyMLDatasetsPython

Measurement & signal processing

Precision multi-channel energy metering, pressure, radar, time-of-flight, pyroelectric and UWB sensing. Filtering, DSP, Kalman tracking, software-defined radio.

Cloud & IoT platforms

Multi-tenant platforms with real-time dashboards, alerts and PDF/CSV reports, MQTT brokers and device management — running on infrastructure we operate ourselves.

Node.jsPostgreSQLRedisLinuxProxmoxVPN

Web & mobile apps

Web apps and dashboards, web interfaces served by the device itself, and native Android apps with push alarms, prepared for Google Play.

ReactAndroidKotlinPush alarms

AI-powered software

Language-model assistants built into our platforms: they read documents, lab results and sensor data, and help specialists reach a decision faster.

LLMDocument AIDecision support

Energy systems

Solar and hybrid inverters, battery management systems, energy meters, heat pumps, export limiting and automated UPS / battery testing.

InvertersBMSMeteringHeat pumps

Building & industrial automation

I/O controllers, HVAC and fan-coil control, building management, wireless zone gateways, alarm and safety systems.

PLC-style I/OHVACBMSGateways

Test automation & production

Automated bench tests driving lab instruments, production programming and test stations, labels and traceability for every unit: serial number, test results and firmware version, recorded automatically.

SCPITest stationsTraceability

Enclosures & 3D

3D-printed enclosures designed in code and checked against the real board for fit and printability — plus interactive 3D presentations like the ones on this page.

How we work

From a conversation to devices in the field.

Talk

What it must do, where it will run, how many units, the budget — and you get a clear plan for getting there.

Prototype

Schematic, board, first firmware and a working demo — usually the fastest way to settle open questions.

Validate

Bench tests, edge cases, a pilot on site. Measurements, not assumptions.

Produce

Series production: machine-assembled boards, test stations, enclosures, labels and documentation — at the volume you need.

Support

Remote updates, monitoring and changes when your needs change.

Engineering, amplified by AI. We combine decades of hands-on electronics experience with AI-assisted design review, verification and documentation. Every check is automated where it can be — and every result is confirmed on real hardware.

A few lines are enough: what the device should do, roughly how many you need, and by when.
