Hi, Thanks for sharing the detailed requirements. I can support the ESP32-based Arduino UNO-style control board design, including schematic, PCB layout, screw-terminal I/O breakout, 2-cell 18650 battery/BMS section, Arduino-compatible firmware setup, and matching ABS enclosure design. My approach would be to first confirm the exact ESP32 module, required UNO pin compatibility, battery configuration, charging method, output current limits, enclosure size, branding details, and whether Wi-Fi/Bluetooth antenna clearance is required. I will then design the PCB in KiCad/Altium with proper ESP32 power supply, USB/programming interface, screw terminal mapping, battery protection, safe power routing, test points, and manufacturing outputs. For the enclosure, I can prepare STEP/STL files with wall-mounting features, standoffs, connector openings, snap/fastener closure, and alignment with the PCB. I can also provide firmware flashing instructions so the board can be programmed from Arduino IDE. Deliverables can include schematic, PCB files, Gerbers/ODB, BOM, firmware image/instructions, enclosure CAD, and prototype support. Since two fully assembled prototypes and enclosure fabrication involve material, PCBA, battery, and shipping costs, I would quote those separately from engineering. Regards,

Hi, I can design a custom ESP32-based control board in the Arduino UNO R3 form factor with screw-terminal I/O, dual 18650 battery support with integrated 2-cell BMS, and a matching ABS enclosure. The board will be fully compatible with the Arduino IDE, preconfigured for easy programming, and delivered with complete hardware documentation, firmware, manufacturing files, and tested prototypes. I have experience designing ESP32 hardware, battery-powered embedded systems, and production-ready PCBs, ensuring reliable wireless performance, safe power management, and a clean enclosure ready for prototyping or manufacturing. I can begin immediately and keep you updated throughout each milestone.

@jtm245

As a seasoned Electronics and Hardware Design Engineer, I've spearheaded numerous projects and brought complex concepts to fruition. I've worked with ESP32 extensively, as well as battery management and mechanically constrained devices. Logistically, I have established relationships with local suppliers and manufacturers for prototyping, small-batch production, and final assembly which means I can facilitate fast turnarounds without compromising on quality. I have worked closely with injection moulding partners previously, which would be advantageous when designing the ABS enclosure. I also have 3D printers to hand for the 2 prototypes requested.

@Webslinger01

I’ve read your brief and this is a straightforward fit for what I do. I’ve been building custom PCBs and firmware for over a decade, including end-to-end projects like a solar-powered RFID water vending machine deployed in South Africa and a Raspberry Pi thermal printer for POS systems. I handle the full stack — schematic design, PCB layout, 3D enclosure modeling, and prototyping. I can deliver a board that’s both ESP and Arduino compatible with a clean, functional enclosure design. No fluff, just a working prototype that ships to you ready to test. Let me know your project requirements and I’ll get you a clear scope and fixed price.

Hi, The challenge here isn't replacing the ATmega328P with an ESP32. It's preserving the familiar Arduino UNO experience while integrating dual 18650 battery management, screw terminals and a clean RF layout into a board and enclosure that's ready for manufacturing, not another design iteration. I recently completed an ESP32 based product where careful power architecture and PCB layout avoided a costly prototype respin while delivering stable wireless performance and reliable battery operation from the first assembled boards. I can deliver your complete schematic, PCB layout, Gerbers or ODB, verified BOM, Arduino IDE compatible firmware, STEP and STL enclosure, and support through prototype validation. Since the posted budget appears to be an initial placeholder, I'm happy to structure the work into phases so each milestone stays focused, measurable, and low risk. My priority is delivering a design that's ready for production, not one that needs engineering fixes afterward. Share any enclosure or branding constraints, and I'll review the architecture and identify the key design considerations before layout begins. One question: should the ESP32 preserve the exact Arduino UNO pin mapping for shield compatibility, or is matching the Arduino IDE workflow the primary goal? Muhammad Umar

Hi, I’ve closely reviewed your project for creating a custom ESP32 control board with an enclosure, and I'm confident my experience aligns perfectly to deliver innovative, professional results. I specialize in 3D Design and Print, which enhances my capability to design precise enclosures and mechanical files that match your specifications, ensuring seamless integration with your PCB layout and wiring needs. My background in PCB Layout and 3D Printing ensures the electronic and mechanical aspects are meticulously coordinated for optimal performance. I will develop the detailed schematic, PCB layout, and industry-standard Gerber files, alongside a complete BOM and straightforward Arduino IDE flashing instructions. My design approach guarantees functionality, like reliable battery management and secure I/O pass-through, and an enclosure that is both practical and visually appealing, ready for injection molding or 3D printing. I am eager to bring my innovative design skills to your project and will provide two tested prototypes for your review. Looking forward to discussing your precise functional and aesthetic goals. How can we further optimize the enclosure design for easier assembly and maintenance, considering the space constraints? Thanks, Rahul

@rakhshanz3

Hi! I design ESP32-based PCBAs with enclosures and this is right in my wheelhouse. I'll deliver a compact, Arduino-compatible ESP32 board that loads Blink from the Arduino IDE at 115200 with no driver fuss, plus a safe battery section (balanced charging, protection, and cutoff at safe limits for both cells), screw-terminal I/O with full continuity and signal integrity, and a snap-shut wall-mount enclosure aligned to the mounting holes. You'll get industry-standard output files (Altium or KiCad), schematic, BOM, Gerbers, firmware and clear documentation, plus two fully assembled and tested prototypes for final verification. I've done solid ESP32 wireless and reliable battery-management work before and can share references. Could you confirm the two cells/battery spec and I/O count? Happy to start right away.
