Nice to meet you rodrigouSW, My name is Anthony Muñoz, I express my interest in working on your project after carefully reading the requirements and concluding that they match my area of knowledge and skills. I am currently the lead engineer for the IT agency DSPro and I have more than 10 years of experience in the field. I have successfully completed a large number of similar jobs and I consider your project to be a challenge in which I would like to work and be able to make it a reality. Please feel free to contact me, it will be my pleasure to help you. I greatly appreciate the time provided and I remain attentive to any questions or concerns. Greetings

✅Hi — I’ve done similar work, and I can already picture how to approach it effectively. I can deliver a fully integrated, production-ready KiCad design for your Orange Pi CM4 carrier board, including Gerbers, BOM, and documentation tailored for JLCPCB or PCBWay turnkey assembly. I am a Full Stack Engineer and hands-on Project Manager with 17 years of experience, providing custom embedded hardware designs, audio interfaces, and CM4-compatible boards using KiCad and Linux SBCs. In my opinion, the key is smart component selection for sourcing reliability and tightly integrated layout planning to ensure clean I2S audio, touchscreen response, and stable power distribution—especially with dual-input (PoE + USB-C) scenarios and audio isolation. This project is very similar to a CM4 carrier I developed featuring a 5" DSI display, I2S DAC with onboard MAX97220A headphone amp, USB ports, and PoE+ input. I also worked on a streaming audio device with rotary UI, physical buttons, and touchscreen—all assembled through JLCPCB with LCSC sourcing. So, I will divide your project into three major steps. Create schematic with validated components and modular block design Layout 4-layer PCB (if needed) with proper routing, shielding, and thermal planning Export Gerbers, BOM (LCSC), and full documentation package I need some details to start the project: touchscreen model/interface, preferred I2S DAC/amp (or let me suggest options), and enclosure constraints if any.
