Node-RED vs Xedge32

Sat, 28 Mar 2026 17:59:58 GMT

This comparison is written for (OT) engineers with some hardware design expertise who are evaluating practical edge-platform options for industrial connectivity, protocol bridging, and embedded device integration. The emphasis is not on generic IT workflows. It is on what helps when you need to connect real equipment, manage device-side logic, and make sound deployment choices close to the machine.

Interpreting CRA Expectations for Embedded Web Interfaces

Thu, 05 Mar 2026 22:03:19 GMT

Many embedded devices include a built-in embedded web server to provide a browser-based interface for configuration and management within Intranets (private networks). While convenient, this design introduces security considerations that are not always straightforward to interpret under modern cybersecurity regulations.

Troubleshooting: When It Looks Like Xedge32 Crashed

Fri, 06 Feb 2026 17:47:02 GMT

When you're developing with Xedge32, the device can behave like a black box if you're not watching its console output. Unlike a laptop or phone, the ESP32 doesn't have a screen or UI that tells you what's going on internally. That means that if Wi-Fi stops working or the network stack gets into a bad state, your board can appear to "just crash," even though the firmware is still running under the surface. In other words, a lost Wi-Fi connection is not a real crash. It's often just the part of

CRA Security Guide for IoT and Embedded Web Servers

Fri, 28 Nov 2025 21:27:55 GMT

The EU Cyber Resilience Act (CRA, Regulation (EU) 2024/2847) introduces mandatory cybersecurity requirements for products with digital elements, including firmware, embedded software, IoT devices, and connected applications. The CRA entered into force on December 10, 2024. Its main obligations apply from December 11, 2027, while the reporting obligations for actively exploited vulnerabilities and severe incidents start earlier, on September 11, 2026.
