@macroenergy

As an experienced electrical engineer with a diverse portfolio that spans across the fields of circuit design, embedded systems and PCB layout, I believe that I am well-suited to handle your project’s needs. Beyond the requirements listed for this initial assignment, I boast a track record of success in designing carrier boards for Raspberry Pi CM4/CM5 and similar SOM/COM models. Moreover, if you need any more convincing of my competence, a core area of my expertise includes embrace digital motor control. Amongst others, I have carried out significant projects on low-speed applications as well as BLDC, Step, and DC motors. Additionally, my knowledge of Analog Design paves the way to noisless OPAMP based analog circuits and Orcad simulations that will come handy in dealing with NMEA0183 and other such marine protocols. As regards to your pricing model; I am open to a fixed-price per project or an hourly rate approach as per your convenience. Also, I would like to notify that while Altium Designer is my primary CAD tool it would not pose any obstruction if you instead prefer KiCad files. newInstance speaking, I understand the urgency of completion/fabrication of this board; therefore I ensure my total devotion to the job; from reviewing existing references to delivering perfect schematic files (KiCad or Altium), PCB layout files even till providing Gerbers, drill files pickup-and-place package etc for the fabrication.

Hi there, I’ve reviewed your CM5 carrier board concept and the scope list, including the CM5 integration, CAN/NMEA interfaces, eDP at 4‑layer impedance‑controlled routing, and marine/industrial robustness. I will consolidate the provided open‑source designs into a clean, manufacturable schematic and a 4‑layer layout with careful impedance control, EMC practices, and verifiable DFM for a small‑boat environment. Deliverables will be fully documented schematic and layout files (KiCad preferred), plus a complete fabrication package (Gerbers, BOM, pick‑and‑place, drill data). For this design‑only phase, I propose a design‑level effort with clear handoffs, while remaining open to fabrication and bring‑up as future work. What are the exact mechanical constraints and environmental requirements (IP rating, vibration, temperature range) for the carrier board, and do you have a preferred CAN transceiver and NMEA 2000 variant to use in this design? Best regards, Marko Aleksic

Hi, I recently designed a carrier board around a compute module platform integrating high-speed interfaces and industrial communication buses. The main challenge was maintaining signal integrity for display and USB interfaces while keeping the CAN network robust in electrically noisy environments. From your description, you need a 4-layer carrier board integrating the Raspberry Pi Compute Module 5 with power management, CAN networking, serial interfaces, and an external display via Embedded DisplayPort. The critical aspects will be proper impedance control for high-speed interfaces, stable power delivery, and reliable industrial communication including CAN bus and NMEA 0183. My approach would be: 1. Review and consolidate the open-source reference schematics 2. Design a clean CM5 carrier schematic with robust power and I/O 3. Define a 4-layer stackup and floorplan for high-speed routing 4. Route eDP and other critical signals with impedance control 5. Deliver full fabrication package (schematics, PCB, Gerbers, BOM) Scope: I can provide **design + prototype fabrication support**, including DFM review and coordination with the PCB manufacturer. Quick question: Do you already have the mechanical constraints and connector placement defined for the marine enclosure, or should this be optimized during the PCB floor-planning stage? Best regards Mykola

Hi, I recently designed a CM4 and CM5 based IO board for industrial communication units used in Utility companies. This board include High speed Ethernet, Serial communication modules, an SSD (yes it's possible on CM4 as well, I added an PCIe to NVMe SSD on this board). I used KiCad for it but I'm comfortable with Altium as well if you prefer that. I can show you the board as a demo if you want. My quote includes PCB design plus fab support including Gerbers and BOM. I can also do prototype testing if you want. I already have reference designs for CM5 Message me and we can further discuss details. Thanks

As an Embedded Systems Engineer with extensive experience in PCB design and Raspberry Pi-based projects, I am confident that I'm the ideal candidate for your 4-layer Raspberry Pi CM5 carrier board project. I have successfully designed carrier boards for similar SOM/COM modules, and I am well-versed in interfaces such as DisplayPort/eDP/HDMI and USB 3 on 4-layer boards with controlled impedance. I can seamlessly integrate the existing open-source designs you will provide while cleaning them up for a robust and manufacturable end result. Moreover, my expertise extends to CAN bus systems and protocols, which aligns perfectly with your project's marine/industrial interfaces requirement. This includes working with NMEA 2000 and NMEA 0183. My multi-disciplinary background also enables me to thoroughly understand and implement your mechanical constraints within design. In terms of CAD tools, I'm highly skilled in KiCad and I can certainly deliver source files in that format if required. Regarding scope, my proposal encompasses design as well as the option for prototype fabrication support. Additionally, my pricing model is based on fixed-price per project; this ensures that you get excellent value without compromising on quality or timelines. Thank you for considering me! Let's collaborate to bring your project to life!

@tetianam8

⭐⭐⭐⭐⭐ This is a good fit for the way I work: take proven open-source building blocks, clean them up properly, and turn them into a robust, manufacturable CM5 carrier board instead of a fragile copy-paste design. I’m comfortable with Raspberry Pi carrier-style boards, 4-layer mixed high-speed layouts, CAN interfaces, and industrial/marine-oriented I/O. For this first phase, I can handle design-only: schematic consolidation, final PCB layout, and a complete fabrication package. I can also support prototype bring-up as a separate follow-on if you want continuity. Preferred CAD: KiCad (can also work in Altium if needed). Quoted scope: Design only Deliverables: source schematic/PCB files, Gerbers, drills, PnP, stackup, BOM. My approach: Review your reference designs and remove weak/duplicate sections Finalize CM5 power, CAN/NMEA0183, eDP, and connector architecture Build a clean 4-layer layout with controlled-impedance attention for eDP and solid EMC grounding practices Deliver a release package ready for fabrication Relevant background: SOM/carrier boards, embedded Linux carrier designs, USB/high-speed routing, and industrial communications layouts. I can also deliver in KiCad source if that’s your preferred long-term format. Quick questions: • Which exact CM5 interfaces are mandatory beyond eDP/CAN/NMEA0183? • Do you already have connector/mechanical envelope constraints? • Is isolated CAN required for the marine side?

I am quoting for the design-only scope, and I will deliver the KiCad schematic and PCB source files along with the complete fabrication package (Gerbers, drill files, BOM, pick-and-place, and stack-up documentation). I would be happy to collaborate long-term on the additional boards you plan after this prototype. I’d be glad to discuss the requirements and references you have. Regards: Tanzeel Ehsan
