Embedded Linux & IoT Consultancy — Dublin on Electronics Consult

PCB Design & Assembly

Mon, 01 Jan 0001 00:00:00 +0000

Getting from schematic to a working board is rarely straightforward — component placement, trace routing, impedance, thermal relief and DFM constraints all interact. At Electronics Consult I work through that process iteratively, optimising layouts for performance and cost before sign-off.

Software Development

Mon, 01 Jan 0001 00:00:00 +0000

Embedded firmware and software development in Dublin. ARM, ESP32, PIC, Raspberry Pi, embedded Linux and Yocto for IoT and connected devices.

There are many powerful microprocessors on the market but what they all have in common is the requirement for quality firmware code development to produce reliable products.

Device Integration

Mon, 01 Jan 0001 00:00:00 +0000

IoT device integration in Dublin: connect devices over Wi-Fi, cellular or LoRaWAN and integrate with cloud services like AWS IoT and ThingSpeak.

When it comes to IoT, connectivity is usually a vital component. We offer experience in the following connectivity methods:

Matter, Thread & Zigbee: What IoT Developers Need to Know Before Choosing

Sun, 26 Apr 2026 00:00:00 +0000

If you’re building a connected product in 2026, you’ve almost certainly been asked: “Are you doing Matter or Zigbee?” The answer is less straightforward than the marketing suggests. Having recently built a working Matter pressure sensor on ESP32-C6 and gone through CSA certification on the Zigbee side, here are the practical differences that actually affect your development timeline, cost, and product viability.

Debugging a Blank Display on an Embedded Board

The One-Line Fix That Took Days
#

or: why your mental model of the hardware matters more than your register dumps
#

A step-by-step debug walkthrough for diagnosing a blank display on an embedded board — the checks, tools and pitfalls from a real engineering project.

AI-Assisted Hardware-in-the-Loop for Embedded Linux

Sun, 15 Feb 2026 00:00:00 +0000

AI-Assisted Hardware-in-the-Loop for Embedded Linux
#

AI coding assistants are genuinely useful for embedded Linux work — navigating unfamiliar build systems, writing device tree overlays, debugging kernel configs. But they hit a wall the moment physical hardware is involved. The agent can modify source files and run builds, but it cannot flash the board, watch it boot, or read back what happened.

CSA Testing — Lessons Learned

Sun, 01 Feb 2026 00:00:00 +0000

CSA Testing — Lessons Learned
#

TL;DR — Lessons learned bringing Zigbee end devices through CSA certification testing: what to expect, common failure modes and how to prepare your firmware.

EFR32 — Accessing Serial Output via RTT from the Command Line

EFR32 — Accessing Serial Output via RTT from the Command Line
#

Setting up Segger RTT for fast debug output on Silicon Labs EFR32 microcontrollers — practical configuration notes from an embedded engineering consultancy.

ESP32 — Enabling PSRAM

Mon, 01 Jan 2024 00:00:00 +0000

ESP32 — Enabling PSRAM
#

How to enable and use PSRAM on the ESP32, with the configuration steps and gotchas you’ll hit in real firmware projects. Notes from an embedded consultancy.

Meritech CleanTech Evo — Automated Handwashing Station

Mon, 01 Jan 2024 00:00:00 +0000

Meritech manufactures automated handwashing stations used in food processing, healthcare and industrial environments. The CleanTech Evo is their flagship unit — a fully automated station that washes and sanitises hands in 12 seconds without any manual contact.

ESP32 Partition Calculations

How to calculate and configure ESP32 flash partitions for OTA updates, NVS and SPIFFS. A practical walkthrough from an embedded engineering consultancy.

Graphical User Interface (GUI) Development

Mon, 01 Jan 0001 00:00:00 +0000

Embedded GUI development for industrial HMIs, touchscreens and Raspberry Pi. Qt and modern responsive interfaces for embedded Linux hardware.

Many embedded projects require a user interface and a common solution is the use of touchscreens. Rendering clean, clear & responsive displays requires careful selection of an appropriate framework. Qt has previously been considered the go-to solution for embedded graphical user interface (GUI). With its extensive development environment coupled with a multitude of libraries it enables rapid progression to market. This, however, comes with a cost, which can be prohibitively expensive.
