Custom Circular PCB with ESP32-C3

I need a custom circular PCB designed and manufactured (including component assembly via services like PCBWay) to integrate several modules into one compact, reliable board.

Requirements:

Microcontroller: ESP32-C3 (bare MCU, not development board)

I previously used the ESP32-C3 Super Mini for testing, but many of its pins, USB port, and onboard buttons are unnecessary

However, red and blue indicator LEDs (similar to the Super Mini) should be included on the custom PCB


Flashing Interface:

A separate, reusable programming jig/module is required (spring-loaded, clip-on, or non-soldered) to flash the MCU before detaching


PCB Form Factor:

Circular PCB

Outer diameter: 33mm

15mm x 15mm square cutout in the center


Power Input:

12V input via 2-pin header

Input passes through a bridge rectifier

Followed by a 12V to 3.3V DC-DC buck converter to power the ESP32-C3


Outputs:

2-pin header to control an external 12V component (200mA coil) via MOSFET

2-pin header for an LED indicator


Control Logic:

The ESP32-C3 will control a MOSFET to switch the 12V power to the external component

The external component is a 12V / 200mA coil that may generate voltage spikes (inductive kickback) when switching; proper protection (such as a flyback diode or TVS diode) must be included to prevent damage to the circuit



Additional Requirements:

The freelancer will place the PCB production and assembly order on PCBWay (or similar service) using my provided shipping details

All files and documentation must be delivered at the end of the project, including:

Schematics

PCB layout

BOM

Gerber files

Any other relevant project files



Please apply only if you have experience in compact embedded PCB design, ESP32-C3 integration, and handling inductive loads safely.
