The main change in this version is that the antenna now extends beyond the LCD cover, improving Wi-Fi signal performance. As a result, the overall size is slightly larger than Version V1.3.

We also designed a new enclosure.

The two side pushbuttons are now functional:

• Left button changes the LCD screen orientation.
• Right button scrolls through LCD information pages.

In previous revisions, one button served as a system reset, but since a quick USB-C re-plug achieves the same effect, we reassigned it for display control.

We’ve also added an opaque protective panel above the LCD for improved durability and appearance.

Feedback and suggestions for additional button functions are welcome!

Carrying Bag

We also found a carrying bag for ESP32JTAG.

We’re confident this version of the hardware is close to the final production version.

Thank you again for your continued support, your feedback and suggestions are always welcome!
