As a seasoned electrical engineer and experienced freelancer, I specialize in intricate PCB designs, especially those with complex and stringent requirements, much like your Annular ESP32 project. I am well-versed in both EasyEDA and KiCad formats, ensuring that your manufacturing-ready Gerber ZIPs and BOM details will be precise and error-free. My extensive understanding of the ESP32-WROOM-32U and other components you've specified for the board guarantees an efficient layout that respects crucial factors like antenna keep-out zones, appropriate routing for UART, I²S, I²C, SPI interfaces, atop more. Additionally, as a part of the distinct services I offer, I'll provide you with the essential editable CAD source files and Pick-and-Place files that are fundamental to your production needs. Uniquely positioned bridge between AI systems and hardware integration through ERP workflows, my stack offers a holistic approach to address complex challenges like yours. Not only will I create a highly functional PCB design but being seasoned in deploying projects on edge devices, I'll ensure that your board is fully compatible with the broader system it operates. So let's make AI communicating with hardware a reality - together!

Hello, I can design the two-layer donut-shaped PCB around the ESP32-WROOM-32U, ensuring the 92 mm OD, 54 mm minimum ID, antenna keep-out compliance, and reliable routing of the GPS, MAX98357A, DS3231, MicroSD, USB-C power, and touch pad within the available ring space. I will deliver editable EasyEDA source files, production-ready Gerbers, NC drill files, BOM with manufacturer part numbers, and Pick-and-Place files. The design will follow JLCPCB design rules and be verified to pass DFM checks before delivery. Looking forward to working on this project.

Hi, You can check my portfolio for ESP32-based PCB projects, including compact IoT devices, GPS integration, audio circuits, SD card interfaces, and production-ready designs for JLCPCB. I can design the 2-layer donut-shaped PCB while respecting the ESP32-WROOM-32U antenna keep-out, routing constraints of the 19 mm ring, and integrating the Quectel L80, MAX98357A, DS3231, MicroSD, USB-C power input, and touch pad. The final design will be optimized for manufacturability and verified against JLCPCB design rules before release. Deliverables will include editable source files, Gerbers, NC drill files, BOM with MPNs, and Pick-and-Place files ready for assembly. Best regards, Ahmed

I've done over a decade of ESP32 and custom PCB work, so an annular design is well within reach. I've shipped boards for vending machines, wearables, and air quality monitors, all with tight form-factor and routing constraints. I'll handle the schematic, layout, and firmware integration so the board works the first time, not just on paper. I also do full prototyping and can ship you working units. Let me know if you want to go over the pin assignments and power requirements before I start.

@soniaer987

I came across your project for the annular ESP PCB design and I have to say, it really caught my attention. I've been working on embedded hardware for about six years now, and projects with unique form factors like this are exactly the kind of challenge I enjoy. I've designed custom PCBs for everything from smart golf balls to industrial controllers, so I'm confident I can handle the layout constraints of a circular board while keeping signal integrity and thermal performance solid. I can also take care of the firmware side if needed, and I'm happy to discuss your specific requirements whenever you're free.

Hello, Your project presents an interesting PCB layout challenge, and it aligns well with my experience in compact embedded hardware design and PCB layout optimization. I am a Hardware Design Engineer with experience designing ESP32-based systems, mixed-signal PCBs, sensor interfaces, power management circuits, and manufacturing-ready boards using KiCad. The donut-shaped form factor and limited routing area require careful component placement, layer utilization, and signal planning, particularly with the ESP32 antenna keep-out, GPS module, MicroSD interface, I²S audio routing, and USB-C power integration. For this project, I can: • Design the complete 2-layer PCB within the specified 92 mm OD and 54 mm ID constraints • Ensure compliance with ESP32-WROOM-32U antenna clearance requirements • Integrate the Quectel L80 GPS, MAX98357A audio amplifier, DS3231 RTC, MicroSD interface, USB-C power input, and capacitive touch pad • Optimize routing for SPI, I²C, UART, and I²S interfaces within the narrow ring geometry • Generate JLCPCB-compatible manufacturing outputs and verify the design against standard DFM rules • Deliver editable KiCad source files, Gerbers, NC drill files, BOM, and Pick-and-Place data I have experience with ESP32, RP2040, STM32, Teensy, and other embedded platforms, along with designing boards intended for automated assembly and production. I can begin immediately after reviewing any additional mechanical requirements or preferred component footprints.

Hello, I have strong experience in compact, multi-layer PCB design for ESP32-based systems, including constrained form factors with strict antenna keep-out requirements and mixed-signal layouts. I can design your 92 mm donut-shaped board with a 54 mm inner cut-out while efficiently routing UART GPS (Quectel L80), I²S audio (MAX98357A), I²C RTC (DS3231), SPI MicroSD, and capacitive touch within the limited 19 mm ring area. I regularly work in KiCad/EasyEDA and ensure all designs pass JLCPCB DFM checks on the first submission, including correct stack-up, trace widths, impedance considerations, and clean power distribution for 5V and 3.3V rails. I also pay close attention to ESP32-WROOM-32U RF layout rules, ensuring proper antenna isolation and stable wireless performance. I will deliver fully production-ready files including Gerbers, NC drill, BOM with manufacturer part numbers, and Pick-and-Place files ready for assembly without revision delays.
