I have very good mixed signal board design experience and have worked a lot on compute modules from Veriscite. CM4 is no different. I will design it in KiCad latest version 9.0.6 in which I have more than 6 years of experience with overall 20 years PCB design experience. I know how to handle low level signals accurately with proper GND signalings and other stuffs required for best analog experience. In case you want to capture details of PF or reactive power and other details, this ADC needs to be captured in realtime. In that case it's better to use a small ad-hoc MCU to capture these details and present the result to CM4 via UART. CM is not good for realtime data capturing and if you need to calculate power factor or voltage/current phase then it wont be suitable. Also this design needs power section to be designed properly. I will design it with all 3D models so that if you have any specific enclosure (Yes, I collaborate with MCAD nicely with my KiCad if you have STEP file) in mind or want to use off the shelf DIN rail mounting enclosure, this would help. Total design charge would be $3000, design duration less than 4 weeks. If you are interested, we can discuss in more details. Thank you.

@AlexandrGergel

Greetings, I recently finished a compact 3-phase metering board that paired a CM4 with an energy-IC (ADE series), dual RS-485, and cellular over M.2. I handled the full stack in KiCad—from isolated GPIO and CT inputs to EMI-safe power—and brought it up on Linux with clean device trees. That mix of CM4, metrology ICs, and industrial comms fits your needs well. The main challenge here is tight layout on 60×100 mm while keeping metrology accuracy, isolation, and RF performance for the 5G and Wi-Fi modules. I’ll split the board into quiet metrology and noisy digital/RF zones, follow ADE9000 Kelvin routing for CT and dividers, enforce creepage/clearance around mains, and give the M.2 + RTL8189 proper ground, keep-outs, and antennas. First demo (schematic freeze, placement, power tree, and critical routing plan) in 7–10 days; full release files in about 3 weeks. Budget fits your range; I estimate 1.1k–1.4k for the listed scope. A question: 1. CT details: ratio, target currents, and preferred connector pitch; any built-in burden or should I size onboard burdens? Sincerely, Oleksandr

@christopherj157

✔️ Best Match! I’ve designed several smart metering and energy-monitoring systems built around ADE-series ICs (ADE7953, ADE9000) and Compute Module 4 (CM4), so your project’s architecture feels very familiar. I can finalize your schematic, optimize the 4-layer PCB layout for low noise and thermal balance, and deliver full fabrication-ready files (Gerbers, drill, BOM with sourcing, and 3D export for enclosure fitting). My workflow emphasizes precision metrology routing (guard rings, Kelvin sensing, creepage spacing), clean power and ground separation, and solid RF layout for the 5G and Wi-Fi modules. I’ll also ensure proper isolation for the five opto-GPIOs and smart-load interfaces, plus well-placed CT and voltage inputs. You’ll receive: • Complete schematic and PCB in KiCad or Altium • BOM with DigiKey/LCSC links • Fabrication + assembly outputs • Optional bring-up documentation and test plan I’ve shipped production boards integrating CM4, LTE/5G modems, RS-485, and AC metering before, and I’m confident I can deliver your prototype within 2–3 weeks inside the stated budget. Let’s discuss your enclosure constraints and any mechanical models so I can align connector placement early.

I’m highly interested in your 3-phase smartmeter project and well-qualified to deliver it. I specialize in PCB and embedded hardware design for energy-monitoring systems and have previously developed compact 4-layer boards integrating Raspberry Pi CM4, ADE9000, and industrial communication interfaces (RS-485, Ethernet, and 5G modules). I’ll finalize your schematic and design a 60 × 100 mm 4-layer PCB in Altium or KiCad, ensuring clean signal integrity, isolation for CT/voltage sensing, and clear separation of high-voltage and logic domains. The board will include the IRM-20-5 AC-DC converter, RM502Q-AE 5G via M.2, RTL8189 Wi-Fi, dual RS-485, opto-isolated GPIOs, and MOSFET/relay load control. Deliverables: full schematic, PCB files, Gerbers, 3D model, BOM with sourcing links, and documentation. I can complete the project in 3 weeks and provide production-ready outputs tested for manufacturability and EMC compliance.
