/about · Who We Are
We read the datasheets so you don’t have to.
Most tech sites tell you what to buy. We tell you what’s inside it. Down to the silicon, if that’s where the answer lives. When a $200 security camera outperforms a $400 one, there’s an engineering reason. We find it. When a spec sheet number doesn’t match what I see on a TruSentry install, I say so. EG3 is an independent tech publication. No manufacturer pays to influence our analysis. The engineering either holds up or it doesn’t.
The EG3 Lineage
Same name, same mission, rebuilt for 2026.
If you remember EG3 from the early web, you’re in the right place. This domain has pointed at embedded-engineering content since 1996, when EG3 was one of the internet’s go-to directories for embedded systems, DSP, RTOS, and development tools. Thousands of universities, vendors, and engineers linked to it, and many of those links still work today because we made sure they land somewhere useful.
To be direct about it: we are not an unrelated company that bought a catchy domain. Today’s EG3 is a deliberate rebuild of the original’s mission, cataloging what embedded engineers actually need to know, updated for how the field works now. The directory model died with the early web. The subject matter didn’t. So instead of link lists, we publish researched, datasheet-cited guides on the same topics the original EG3 indexed: microcontrollers, signal processing, real-time systems, and the tools that build them. The 8051 pages gave way to Cortex-M and RISC-V. The spirit is unchanged.
Our Methodology
How we research.
01
Primary Sources
Every guide starts with datasheets, reference designs, FCC filings, and manufacturer TRMs. Not blog posts. Not press releases. The actual documentation that engineers read.
02
Engineering First
If a thermostat runs a PID loop, we explain PID. If an inverter uses MPPT, we walk through the signal chain. The spec number means nothing without the context around it.
03
No Pay-for-Play
Nobody pays to be recommended here. We earn revenue from content and traffic. When we recommend something, it’s because I’ve either installed it through TruSentry or read enough teardown data to trust the engineering.
04
Quarterly Reviews
Specs change. Firmware updates break things. New silicon ships. We review every guide quarterly and update when the underlying tech moves. Every guide shows its last-reviewed date.

The Reviewer
Editorial Standards
Corrections & contact.
We take accuracy seriously. If you find an error in any guide — a wrong spec number, an outdated firmware version, a misidentified chipset — email us at editor@eg3.com and we’ll correct it within 48 hours. Corrections are noted at the top of the affected guide with the date and nature of the change.
For general questions, press inquiries, or partnership discussions, use the same address: editor@eg3.com.
Every guide starts with primary technical sources. Datasheets, reference designs, IEEE papers, manufacturer documentation. Not blog posts, not press releases, not marketing collateral. Field observations from TruSentry installations supplement the specs. When the spec sheet doesn’t cover something, we check it in the field. When we can’t verify a claim either way, we flag it.
