EN 18031 Explained: EU IoT Security Standard for RED
EN 18031 Explained: Meeting EU Security Standards for IoT Devices Wireless products that connect to the internet, handle personal data, or handle monetary value must meet the RED cybersecurity requirements. This comes from Delegated Regulation (EU) 2022/30 and its amendment that moved the due date to 1 August 2025. The EN 18031 series is […]
A Step-by-Step Guide to Comply With the EU RED Cyber DA (for Hardware Manufacturers)
As of 1 August 2025, the RED Cybersecurity Delegated Act (Cyber DA) is in effect . This means all wireless products sold in the European Union must now meet mandatory cybersecurity requirements. For hardware manufacturers, it’s a market access issue. Without compliance, your products cannot legally be sold in the EU. This guide walks […]
How to Comply an Existing IoT Device With RED Cyber DA Without Redesigning Hardware
The EU’s RED Cybersecurity Delegated Act (2022/30) comes into force in August 2025, making cybersecurity compliance mandatory for all internet-connected radio devices sold in the EU. This includes WiFi, BLE, and cellular-enabled devices, even if they are already CE-marked. At Oxeltech, we provide RED Cybersecurity compliance support for connected devices. Many clients ask: Do […]
What Every IoT Manufacturer Selling in EU Must Know About RED Cyber 2025
From 1 August 2025, the EU’s Radio Equipment Directive (RED) will enforce mandatory cybersecurity requirements for all internet-connected radio devices. This change affects nearly every manufacturer selling connected products, including those using WiFi, Bluetooth, or cellular technologies. What’s Changing? The RED Delegated Regulation (EU) 2022/30 activates Articles 3(3)(d), (e), and (f) of the directive. […]
SoC vs. SoM in Low-Power Devices
A SoC is a single chip that integrates key functions but requires external components, while a SoM is a ready-to-use module that includes a SoC plus supporting circuitry like power, memory, and RF, simplifying integration. The decision which one to use is a trade-off between full control (SoC) and faster deployment with lower RF risk […]
Hunting a Memory Leak that Crashed Remote Devices
Credit: www.blues.com Introduction Imagine a fleet of embedded devices deployed across the country, running smoothly for weeks—until, without warning, they stop communicating. That was the mystery we faced when a customer reported a baffling issue in their widely deployed product. After extended uptime, devices would suddenly and silently stop communicating with the central server. The […]
Coredump Can Help You with Embedded Firmware Debugging (Better than Breakpoints)
Source: embeddedcomputing Coredump captures the crash moment of an embedded system. It shows memory, registers, and stack traces. Firmware bugs are tricky. Hardware-software interactions are complex, resources are constrained, and runtime behavior can sometimes be unpredictable. For teams working on developing embedded products, this can feel like navigating in the dark. To reach the core […]
How to Select the Right Microcontroller for Your Embedded System?
Choosing the right microcontroller is like laying the foundation for your embedded system—get it wrong, and you risk delays, cost overruns, or an outright redesign. The microcontroller (MCU) you choose will determine not just the technical feasibility of your product but also its cost, scalability, and long-term reliability. And there is no free lunch and […]
Design Guide for Battery Safety in Wearable Electronics
Wearable devices often use Lithium-Ion or Lithium Polymer batteries, which have a high flammability risk. This is due to higher energy density and the use of flammable electrolytes inside Lithium-based batteries. Safety against fire and explosion is critical in wearable and consumer electronic devices (this goes without saying). But how do the designers ensure […]
eSIM – Its Benefits & How to Integrate it into Your IoT Hardware
An eSIM (embedded SIM) is an alternative to a traditional SIM (Subscriber Identity Module) card. Unlike traditional SIM cards, eSIMs do not require physical swapping to be reprogrammed for a different cellular network provider. In this blog, when we refer to eSIM, we mean an IC that can be soldered onto your PCB, such as […]
