PCB Modification + 3D Enclosure Update (ESP32 with External Antenna)

I am looking for an experienced hardware/PCB designer with expertise in both PCB layout and 3D enclosure design.

The task includes:

PCB Modification
-Replace the existing ESP32 chip with an ESP32 model that supports an external antenna.
-Review the current layout for any minor improvements.
-Ensure the design complies with JLCPCB’s manufacturing standards (PCB production at JLCPCB).

3D Enclosure Update
-Add a mounting/hole for an external antenna.
-Modify the design so the enclosure can be assembled with screws instead of the current solution.
-Ensure the design meets JLCPCB’s 3D printing standards.

Materials Provided:
-Existing PCB layout (Gerber/PCB source files).
-3D CAD files for the enclosure.

Estimated Time:

The changes are expected to take approximately one working day.

Requirements for Freelancer:

-Proven experience with ESP32-based PCB designs.
-Familiarity with JLCPCB manufacturing standards (both PCB and 3D printing).
-Experience with 3D modeling (e.g., Fusion 360, SolidWorks, FreeCAD, or similar).

Deliverables:

-Updated PCB files ready for production at JLCPCB.
-Updated 3D CAD model of the enclosure ready for 3D printing at JLCPCB.
