Redesign Raspberry Pi CM4 NAS Carrier Board

@macroenergy

Hi there! My name is Metin and I specialize in circuit design, electrical engineering, and embedded systems. With over [number of years] years of experience in the field, I have gained significant expertise that your project demands. As seen from my Github profile, I am familiar with KiCad schematic, PCB design, BOM creation and other technical aspects related to this project. Additionally, my proficiency in utilizing through-hole components and knowledge of Raspberry Pi will play a crucial role in ensuring a reliable and robust redesign for your CM4 NAS Carrier Board. In order to design a board prioritizing reliability and efficient debugging, I have experience not only in Raspberry Pi but also in motors control systems that help detecting intricate issues that may hamper performance. My expertise stretches across analog design as well, which will guarantee no-nonsense opamp-based circuits making debugging hassle-free. Moreover, I understand the necessity for clear labeling of components and test points. Rest assured, I let no room for ambiguity when it comes to documentation: clear silkscreen labels and concise explanations are part of my process. Thank you for considering me for this job; I assure you that with my skills and dedication to meticulous workmanship, your redesigned Raspberry Pi CM4 NAS Carrier Board will be exactly what you need!

With over 8 years in the field, my experience as an Electrical/Electronics Engineer and Professional PCB Designer directly aligns with the redesigning demands of your project. My proficiency in utilizing Eagle, Altium, KiCAD, and EasyEDA, as seen in my extensive portfolio, coupled with my passion for PCB design and embedded systems, have enabled me to deliver high-quality circuit boards that prioritize reliability and provwię easy debugging for manual assembly. One of my recent projects involved the design and prototype of a similar carrier board which successfully incorporated regulated power inputs, fused protection and clear silkscreen labels like what you require. Another critical requirement- bulk capacitors for a 5.1V(≥5A) power source was better experienced through this prototype. Finally, as a preferred freelancer ranked among the top 1% of professionals on this platform my dedication to quality workmanship and delivering on time remain unrivaled. By hiring myself, you are investing in expertise that synergistically merges your vision with technological reality to give you not only a functional product but also one that is aptly documented for future purposes through meticulous schematics, PCB designs & layouts along with a comprehensive BOM. Choose quality, choose me!

Hi, I can handle this cleanly and reliably. I design debug-friendly, manually assembled PCBs with a strong preference for through-hole parts where it makes sense. For your CM4 board, I’ll focus on robustness, clear boot control, and serviceability rather than unnecessary complexity. What I’ll deliver: * KiCad schematic and PCB using 12 V DC → 5.1 V (≥5 A) regulation * Reverse-polarity protection, fuse/PTC, and proper bulk capacitance * Standard CM4 boot control via jumper or switch on nRPI_BOOT (no MCU) * Correct nRPI_ENABLE pull-up with optional manual reset * Clear silkscreen labels and accessible test points (12 V, 5 V, 3.3 V, BOOT, ENABLE) * Supplier-ready BOM and a short explanation of the power and boot design The goal is a board that’s easy to assemble by hand, easy to probe, and predictable during bring-up. I’ll stay aligned with the reference design intent from your GitHub while improving clarity and reliability. If this fits, I’ll review the repo in detail and confirm any component or form-factor constraints before starting. Best regards Abbas P.S. I’m especially careful with CM4 power sequencing and boot strapping, as those are common failure points during first power-up.

Hi, I worked on a project similar to yours last month, using Raspberry Pi for full IoT integration. I have a complete list of components, firmware, and an electronics lab, so I can test everything on my end. Payment will be requested only after successful testing. Let’s discuss the details and start soon. Thanks, Himanshu
