With over 8 years of PCB design and layout experience, I'm confident I can provide the high-quality, manufacturing-ready design files you need for your IoT trap monitor device. I'm well-versed in using Eagle, Altium, KiCAD, and EasyEDA - the precise tools you're looking for. My professional experience with EasyEDA even earned me a certification (which can be viewed in my portfolio). One key aspect of this project is the specific requirements around firmware compatibility. I understand the importance of maintaining consistency and avoiding any unnecessary modifications that could impact your existing firmware. To ensure this, I will diligently study your provided specifications and firmware `config.h` file to guarantee all GPIO assignments, UART configs, power rail voltages and logic levels align precisely to keep your firmware intact. My proficiency in Power Supply Design and understanding of RF antenna routing (50Ω controlled impedance) will be valuable in crafting a PCB optimal for low-power consumption and efficient conductivity for GPS usage respectively. Moreover, my familiarity with ESP32 designs and cellular modem integration (specifically Quectel) ensures a solid foundation for Phase 1 of this project. Let's move forward together on executing Phase 1 efficiently & effectively while setting up for a perfect transition into Phase 2.

Hi, From your description, you need a development PCB integrating the ESP32-S3-WROOM-1-N8, Quectel EG800Q-EU, and u-blox MAX-M10S while keeping the exact GPIO mapping so the existing firmware binary runs without modification. My approach would be: 1. Review your `config.h` GPIO map and hardware specification 2. Create schematic with correct 3.3V/3.8V rails and level translation 3. Place modules with proper RF separation and 50Ω antenna routing 4. Optimize power paths for low-power sleep and modem peak current 5. Generate full JLCPCB-ready manufacturing package for Phase 1, do you prefer using **breakout modules for the EG800Q and MAX-M10S**, or should I place the bare modules directly on the carrier PCB? Best regards Mykola

@leonidye

Hello, I can deliver the complete Phase 1 PCB design package quickly, ensuring the schematic, layout, and manufacturing files match your provided specification and firmware config.h GPIO mapping exactly so the same firmware runs without modification. I have experience with ESP32-based IoT hardware, cellular modem integration, low-power designs, and preparing JLCPCB/PCBWAY-ready Gerbers, BOM, and pick-and-place files for fast prototype production. If required, I can also assemble and functionally test 3–5 prototype boards (power, LTE registration, GPS fix, and deep-sleep verification) to accelerate your field testing timeline. Best regards

Hello, I’m an experienced PCB designer specializing in low-power IoT and cellular-connected embedded systems. I can deliver the complete Phase 1 design package including schematic, PCB layout, Gerbers, BOM, pick-and-place files, and 3D renders ready for JLCPCB or PCBWAY assembly. I have prior experience working with ESP32 platforms, Quectel cellular modules, GNSS receivers, and solar-powered battery systems, which aligns closely with your trap monitoring device requirements. I will ensure the GPIO mapping, UART configuration, and voltage levels match your provided config.h exactly so the same firmware binary runs on both Phase 1 and Phase 2 boards without modification. The carrier-board approach using dev modules is a sensible strategy for rapid prototyping, and I can design the layout to keep RF paths clean and power rails stable for reliable LTE and GNSS performance. My quote for the design files (schematic, layout, Gerbers, BOM, documentation) is $900 USD, with an estimated turnaround of 5 days once all materials are provided. As an optional add-on, I can also arrange 3–5 assembled prototype boards with basic functional testing (power, modem registration, GPS fix, deep sleep current, trigger wake) for $350 USD plus component and fabrication costs. I’m comfortable iterating quickly during development and can also support Phase 2 integration and RF-aware production design after field testing. Best Regards

Okay, I got what you want exactly. I am a Full Stack Engineer PCB Designer with 15 years of experience, providing PCB schematic design, ESP32 integration, RF-aware layout, cellular/GNSS module interfacing, and low-power IoT hardware design. In my opinion, the key point of this project is maintaining firmware compatibility while building stable hardware. I will follow the exact GPIO mapping from your config.h so the same firmware runs on both Phase 1 and Phase 2 boards. At the same time, I will design stable power rails and proper RF routing to ensure reliable LTE and GNSS operation in outdoor environments. This project is very similar to my previous works. I designed ESP32-based remote monitoring boards with LTE modem and GNSS modules for solar-powered outdoor devices. I also built carrier PCBs using development modules and prepared Gerber, BOM, and assembly files for JLCPCB prototype production. One of the most important skills for this project is low-power IoT hardware architecture with RF-aware PCB layout. I focus on stable power delivery, correct level translation (3.3V ↔ 1.8V), and reliable antenna routing. ✅ So, I will divide your project into three major steps. 1️⃣ Design the schematic and confirm GPIO compatibility. 2️⃣ Create PCB layout with proper RF and power design. 3️⃣ Deliver Gerbers, BOM, and PnP files for fabrication. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project. Best regards.

Hi, I’m an Senior Electronics Engineer with deep expertise in low-power IoT hardware, ESP32 systems, and cellular/GNSS device design for remote deployments. I’ve designed 30+ PCBs for battery-powered monitoring systems, including wildlife trackers, solar IoT nodes, and LTE-connected sensor platforms using ESP32, Quectel modems, and u-blox GNSS modules. For this project: ✅ I will implement the carrier PCB design around the ESP32-S3, EG800Q modem, and u-blox M10 GNSS, ensuring the GPIO mapping exactly matches your firmware config.h so the same binary works for both Phase 1 and Phase 2 boards. ✅ I will design the power architecture for ultra-low power operation, integrating the LiFePO4 battery system, CN3767 solar charger, buck/LDO rails, and ensuring clean power delivery for the modem during LTE transmission bursts. ✅ I will apply proper RF layout practices including controlled impedance routing, antenna feedline design, and separation of GNSS and LTE paths to ensure reliable connectivity for both Telstra Band 28 and Starlink Direct-to-Cell Band 7 operation. I am confident I can deliver a reliable, low-power PCB design quickly while maintaining full firmware compatibility, ensuring your Phase 1 field testing can begin as soon as possible. Looking forward to hearing from you. Best,

This is a very good fit for my background. I have extensive experience designing battery powered embedded boards with ESP32, GNSS, LTE modules, level shifting, solar charging, and low power operation for outdoor deployments. Since your hardware specification, BOM, and firmware pin map are already prepared, I can focus on turning the design into a clean Phase 1 PCB package ready for JLCPCB or PCBWAY without unnecessary delay. I can also support the optional prototype build and first functional checks so the boards are ready for field testing as soon as possible.
