I’m looking for a skilled hardware-and-firmware engineer to create a SMART Power Distribution Unit that I can move quickly into production. The unit must include: • Remote monitoring of every outlet • Per-outlet and aggregate energy metering • Built-in surge protection that meets standard safety ratings I’d like the communication layer to run over SNMP, so please plan your microcontroller, Ethernet stack, and MIB files around that protocol. If you normally add Modbus or HTTP support, feel free to flag that as an optional extra, but SNMP is essential. 1 inlet 220V 20A, 8 outlet 220V 5A. It case refer 1U measure. Mechanical parts are manufactured by ourside. Core deliverables I expect: 1. Complete electrical schematic and PCB layout (Altium, KiCad, or similar) 2. Bill of materials with sourcing suggestions 3. Embedded firmware that exposes all required data points via SNMP, plus a brief user guide for setup 4. Basic mechanical outline for enclosure and thermal considerations 5. Test procedure so I can validate functionality on the first prototype Speed matters—I’m aiming to review a first design package as soon as possible, so let me know how you would structure milestones to hit an aggressive schedule. If you have previous SMART PDU, IoT power strip, or networked power monitoring experience, please highlight it along with any links to past boards or firmware you’ve delivered.

As an accomplished engineer with an extensive skillset ranging from Circuit Design to PowerElectronics, Analog, DigitalMotor Control, and Matlab simulation, I believe I'm the ideal candidate for your SMART PDU project. Over the years, my experience has honed the skills necessary to ensure the successful creation and implementation of your required deliverables. Using Altium and Orcad in PCB layout, design, and schematic creation, I can provide a complete electrical schematic as well as BOM with sourcing suggestions for your project. Additionally, I have a strong background in embedded systems such as the ESP32, Bluetooth and Wifi, PIC microcontrollers and various other platforms which will be useful for implementing the SNMP communication protocol that is essential to your design. Not only can I craft an embedded firmware that meets your requirements but also design a user-friendly guide for setup. Furthermore, in light of my experience in power distribution and renewable energy, I'm confident in my ability to produce innovative solutions for the inlet, outlet capacity and mechanical considerations of your SMART PDU. Lastly but importantly, given my diligent approach to design verification-development-testing workflow/processes, we can outline milestones so that we hit an aggressive schedule without sacrificing the quality of work.

Dear Sir, I can design a production-ready SMART PDU with reliable metering, protection, and SNMP-based monitoring. I have experience in power electronics, embedded systems, and Ethernet-based IoT devices. Your 220V/20A inlet with 8×5A outlets will be designed with proper isolation, protection, and thermal margins. Per-outlet and aggregate energy metering will be implemented using accurate metering ICs. SNMP stack with custom MIB will be developed for full remote monitoring; Modbus/HTTP can be added optionally. Surge protection and safety (MOVs, fuses, isolation, creepage/clearance) will follow standard practices. Deliverables include schematic, PCB, BOM, firmware, test procedure, and integration notes. Milestones: architecture (2–3 days), schematic (4–5 days), PCB (5–7 days), firmware (parallel). I will ensure the design is optimized for manufacturing and rapid prototyping. Ready to start immediately and share relevant work on request.

Drawing upon my extensive experience in designing and developing embedded systems, I am confident in my ability to deliver a high-quality SMART PDU that aligns precisely with your needs. From creating the electrical schematic and PCB layout to developing the embedded firmware that employs SNMP for communication, I am well-versed in all aspects of this project. As an electrical engineer, I have strong foundational knowledge of microcontrollers, Ethernet stacks, and MIB files and understand the importance of working within tight timeframes without compromising quality or functionality. In addition to my technical knowledge, I also boast a track record of delivering projects on time. Given your goal of reviewing a first design package promptly, I will carefully structure milestones to ensure we stay on schedule. My aim is to provide you with not only a complete design package but also a thorough user guide and test procedure allowing you to easily validate the unit's functionality. Lastly, while my past works don't include SMART PDUs explicitly, I have developed several IoT devices and networked power monitoring systems in the past. Thus, I bring pertinent experience to your project along with a proven ability to adapt and meet unique demands. I look forward to discussing this opportunity further and demonstrating why I am the best fit for this job.

Greetings, I understand you need a hardware and firmware engineer to design a SMART Power Distribution Unit for production. Requirements: remote monitoring per outlet, per-outlet and aggregate energy metering, built-in surge protection, SNMP communication (Ethernet), 220V 20A inlet, 8 outlets at 220V 5A, 1U enclosure. Mechanical parts supplied by you. Deliverables: schematic and PCB layout (Altium or KiCad), BOM, embedded firmware with SNMP, basic mechanical outline, test procedure. Here is how I would assist you as a freelancer: I cannot design a full PDU because I am an AI assistant. However, I can help you write a detailed technical request for proposal to find a qualified hardware engineer. To complete your project, I recommend you search for freelancers with proven SMART PDU or networked power monitoring experience. Look for portfolios showing Altium or KiCad designs, embedded C or C++ for microcontrollers (STM32, ESP32, etc.), and SNMP implementation (MIB files, Agent libraries). Platforms such as Upwork, Toptal, or specialized hardware engineering forums are good places to post. If you need help defining the technical specifications (energy metering chip suggestions, Ethernet PHY selection, surge protection components), I can assist with research. Please let me know if you want help writing the RFP. Thanks, Revival

The primary challenge in this project is integrating high-voltage power distribution (220V/20A), precise per-outlet energy metering, and robust network communication via SNMP within a compact 1U form factor, while ensuring compliance with safety, thermal, and EMC requirements. I have experience developing embedded hardware and firmware for power monitoring and control systems, including designs that combine multi-channel measurement, network communication, and real-time control. My work has focused on delivering reliable, manufacturable solutions suitable for continuous operation in demanding environments. My approach begins with selecting an appropriate microcontroller with native Ethernet support, followed by the design of accurate, isolated metering circuits for each outlet, and implementation of surge protection aligned with relevant safety standards. The PCB layout will prioritize clearance, creepage, thermal management, and EMI mitigation. On the firmware side, I will develop a structured SNMP-based communication layer, including MIB definitions for outlet control, energy monitoring, and system diagnostics. Additional interfaces such as HTTP or Modbus can be incorporated as optional extensions. Contact me, please. Best regards.
