@yaroslavmark

✅Okay, I got what you want exactly. I am an Embedded Hardware & PCB Design Engineer with over 10 years of experience, providing custom PCB design, ESP32-based systems, I²C sensor integration, and JLCPCB-ready manufacturing files. This project is very similar to my previous works. I’ve designed several ESP32 and STM32 carrier boards that connected 5–8 I²C sensors on a single bus, including CO₂, temperature/humidity, light sensors, and OLED displays, all with mixed JST, RJ, and pin-header connectors. In one recent project, I delivered a 2-layer KiCad design with a 5V input, onboard 3.3V LDO, shared pull-ups, full BOM, pick-and-place, and JLCPCB assembly without any revisions needed. ✅ So, I will divide your project like following: ⚡ Review dev board pinout, power requirements, and I²C addressing ⚡ Create schematic with power regulation, pull-ups, connectors, and protection ⚡ Design clean 2-layer PCB with proper grounding, routing, and mounting holes ⚡ Prepare Gerbers, BOM, and pick-and-place files for JLCPCB ⚡ Optional 3D render and final design review Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and i want to discuss about the budget and timeline in detail. Best regards. Yaroslav

@TheDesignBloke

Hi there, I went through your project carefully, and the core challenge is clear: designing a custom PCB for the ESP32-S3 Dev Board that seamlessly connects multiple I²C sensors requires precision and expertise. This isn’t a surface-level task — it needs someone who understands PCB design and can execute without hand-holding. I’ve handled similar work where clean layout and effective I²C routing mattered. My approach is straightforward: I will create a two-layer PCB design using KiCad, ensuring proper grounding, decoupling capacitors, and clear silkscreen labels for manufacturability by JLCPCB. No guesswork, just results that are ready for fabrication. If this aligns, I can start immediately and deliver the Gerber files and schematic within 10 days. One quick question before I proceed: What specific I²C sensors do you prioritize for this project? Best regards, Muskan

@julianm260

Hello, I’m an embedded systems and PCB design engineer with 8+ years of experience designing manufacturable microcontroller carrier boards and sensor hubs, and I’ve carefully reviewed your ESP32-S3 I²C sensor PCB requirements. I’ve completed 25+ custom PCB designs, including 10+ ESP32-based boards and 15+ multi-device I²C networks, all fabricated and assembled through JLCPCB without revisions. For this project, I’ll design a 2-layer carrier PCB for the ESP32-S3 Dev Board with clean I²C routing, a single 4.7kΩ pull-up set, proper grounding, and decoupling placed per best practices to ensure stable sensor communication. I’ve integrated sensors like SCD30, BH1750, SHT4x, and OLED displays multiple times, and I routinely handle mixed connectors (pin headers, JST-GHR, RJ12) with correct pinouts and pull-configurations such as the 10kΩ SEL-to-GND requirement you mentioned. I typically deliver production-ready schematics, PCB layout, Gerbers, drill files, BOM, and Pick-and-Place files on the first pass, with an average turnaround of 5–7 days for boards of this complexity. I also provide optional 3D PCB renders to help verify connector placement and enclosure fit before fabrication. You’ll receive files fully compatible with KiCad or EasyEDA and ready for direct upload to JLCPCB. If you’d like, I can confirm regulator choice/current budget and preferred board dimensions before starting to avoid any revisions.

@ahmedy607

Hi, Please check my portfolio — these types of ESP32 sensor network projects are exactly what I handle regularly. I’ve carefully reviewed your project details, and this is exactly the type of PCB design I usually work on. While the project could be implemented on a 2-layer PCB, this may lead to challenges with power distribution, signal integrity, and I²C reliability. I strongly recommend a 4-layer design to ensure proper grounding, clean I²C routing, and overall robustness. The PCB will serve as a carrier for the ESP32-S3 N16R8 Dev Board, connecting all your I²C sensors (SCD30, SEN0394, SEN66-SIN-T-ES, SHT40I, BH1750, and OLED display), with 3.3V regulation, decoupling capacitors, mounting holes, connectors, and clear silkscreen labeling. I can provide for you: Schematic and PCB layout in KiCad or EasyEDA JLCPCB-ready Gerber, drill, BOM, and Pick-and-Place files Optional 3D PCB render Recommendations for decoupling, pull-ups, and component placement for clean I²C operation Ready to start immediately. Best regards, Ahmed

@joaquinc48

✅✅✅Embedded Hardware / PCB Design Engineer (ESP32)✅✅✅ Hi there, I have hands-on experience designing custom ESP32-based carrier boards and sensor hubs, including ESP32-S3 modules, multi-device I²C buses, and JLCPCB-ready layouts. I’ve delivered clean 2-layer PCBs with proper power regulation, pull-ups, decoupling, and clear silkscreen for assembly and debugging. My approach is to start with a robust schematic, validate I²C addressing and pull-up strategy, then route with short, clean SDA/SCL paths and solid grounding. I focus on manufacturability, BOM compatibility with JLCPCB, and clear documentation for smooth fabrication. Is the ESP32-S3 Dev Board footprint fixed or vendor-specific? Do all sensors run at 3.3 V only? Are there enclosure or board-size constraints to consider? I am ready to start immediately. Best regards

@SebastianHamburg
