Since hardware production for ESP32JTAG is progressing smoothly, the EZ32 team has also been building something exciting behind the scenes: AEL (AI Embedded Lab).

Part 1 — AEL Announcement

We are very excited to announce that AEL is now in good shape and available to try today.

AEL is completely free and open-source, released under the Apache License 2.0, and already available on GitHub.

More importantly, for ESP32JTAG users, this is not just another software project. We believe it may become a genuinely exciting free gift for everyone who supports ESP32JTAG.

What Is AEL?

AEL is an AI-driven embedded development system that allows AI to work directly with real hardware.

With AEL, AI can:

• Generate embedded firmware
• Flash firmware onto a microcontroller
• Capture and analyze signals from the target hardware
• Observe system behavior
• Debug problems automatically
• Verify whether the result matches the goal
• Generate a final report

In other words, AEL makes it possible to do fully AI-driven embedded vibe coding on real hardware.

Here is a short video to give you a quick feel for how this works in real life:

Yes — I’m actually using my phone to keep an SSH connection open to my PC, so I can check on the AI’s progress and give it instructions whenever needed. Surprisingly, this has become one of my favorite ways to work.

I don’t need to stay in front of a desktop. I don’t need to manually write code, open an IDE, compile, flash, step through code, or set breakpoints over and over again. The AI handles the heavy lifting, while I focus on goals, direction, and review.

And the best part is — I can do this from anywhere. On the couch, in a café, or even lying on the beach.

That shift in workflow feels remarkable. It is not just faster — it feels like a genuinely new way to do embedded development.

I’m incredibly excited about it, and I can’t wait to share more with you.

Why Does ESP32JTAG Matter Here?

ESP32JTAG was designed from the beginning not only as a tool for human engineers, but also as an instrument that can be used directly by AI.

Because ESP32JTAG has built-in Wi-Fi connectivity, it can communicate with AEL directly over the network. At the same time, it can perform MCU flashing and signal capture in one integrated workflow.

That combination is what makes ESP32JTAG especially exciting in this context.

It means ESP32JTAG is not just a debugger or programmer. It may be one of the first real products that can support AI-driven embedded system development in a practical way.

Imagine Embedded Vibe Coding Like This

Suppose you have an STM32F411 board connected to ESP32JTAG, and the wiring has already been defined.

You simply tell AEL:

Generate firmware for this STM32F411 board so that one GPIO visibly blinks an LED, while four other pins output signals at different frequencies. Then flash the firmware, capture those signals with ESP32JTAG, verify that the behavior matches the request, debug if needed, and return a report.

With this workflow, you do not need to do any of the following manually:

• Write the firmware
• Flash the chip
• Probe and inspect signals
• Debug every issue yourself

Instead, AEL and ESP32JTAG can work together to complete the full loop automatically:

• Code generation
• Flashing
• Signal capture
• Analysis
• Debugging
• Verification
• Final reporting

That is the part we find especially exciting. It is a fundamentally new workflow: AI is no longer only helping write code on screen — it is directly interacting with physical embedded hardware, observing real results, and iterating automatically.

What Comes Next?

We are currently preparing a tutorial and a more detailed in-depth article to show how AEL works together with ESP32JTAG in real embedded development scenarios.

When you receive your ESP32JTAG and see this style of AI-driven embedded development in action, we believe you will find it just as surprising and exciting as we did.

Part 2 — ESP32JTAG Production Update

Here is where we currently stand on the production side of ESP32JTAG.

Production & Testing

Hardware production has been progressing smoothly.

Each unit has gone through functional testing to ensure everything works as intended, and so far the results have been solid and consistent.

Packaging Preparation

All packaging materials are now ready, including:

• Product labels
• Small accessory bags
• Protective packaging materials
• Other supporting items required for shipment

Everything is prepared and waiting for the final step before packaging begins.

Final Remaining Component: The Cable

At this point, the only remaining item is the ESP32JTAG cable, which is still being manufactured.

The factory is currently working to complete cable production as quickly as possible. Once the cables arrive, we will immediately begin final packaging and shipping preparation.

All other materials are already in place.

Project Status

Overall, the ESP32JTAG project remains on track, and we have not encountered any major unexpected issues during production.

If everything continues as planned, we expect to begin shipping to customers by the end of this month, or very close to it.

Thank You!

Thank you all for your patience and support throughout this process. Your enthusiasm for ESP32JTAG has been incredibly encouraging, and we are excited to get these devices into your hands very soon. We will continue to share updates as we move into the shipping phase.
