I am ready to move from concept to production on a 55-Zoll LCD Digital-Signage-Screen and need an experienced hardware developer to guide the full electronics side. The panel size is fixed at 55", and my preferred control solution is a Huidu motherboard, Android 13, 14; if you have a strong case for an equivalent European board, we can discuss it— The job covers everything between the raw panel and a turnkey prototype: selecting the exact Huidu mainboard model, designing or adapting the logic board, defining all I/O (HDMI, USB, Ethernet, Wi-Fi, audio, power input, service port), creating schematics and PCB layout, and supplying a production-ready BOM with component alternatives that are immediately sourceable in Europe. I will also need the firmware flashed, tested, and demonstrated running looped media so we can verify stability, The idea is that we will build a digital signage screen under your guidance, with all the necessary modules.

Hello, I understand you need a full hardware and software setup for a 55" digital signage display, from selecting the control board to a turnkey prototype ready for production. My approach focuses on designing a stable, production-ready system that integrates your preferred Huidu motherboard (or equivalent European-sourced alternative) with all necessary I/O, firmware, and media playback capabilities. I will select the exact mainboard, adapt or design the logic board, define HDMI, USB, Ethernet, Wi-Fi, audio, power, and service ports, and create schematics and PCB layouts. A production-ready BOM with alternative components available in Europe will be provided. Firmware will be flashed and tested to run looped media, ensuring stability, reliable playback, and seamless operation. The final deliverable will be a fully documented prototype ready for replication, including PCB files, BOM, firmware, test results, and a demonstration of looped content playback on the panel. This ensures the signage system is reliable, maintainable, and immediately actionable for production. Thanks, Asif.

Hi, From your description, you need full electronics development for a 55-inch digital signage screen built around a controller such as a Huidu Android motherboard. The key aspects will be selecting the correct controller for the LVDS or Embedded DisplayPort interface of the panel, designing the supporting logic board, defining all I/O (HDMI, USB, Ethernet, Wi-Fi, audio), and preparing a production-ready BOM with components available in Europe. My approach would be: 1. Identify the exact LCD panel interface and electrical requirements 2. Select the appropriate Huidu controller or compatible Android board 3. Design the interface PCB with power regulation and connectors 4. Define I/O architecture and service/debug interfaces 5. Deliver schematics, PCB files, BOM, and prototype validation documentation Quick question: Do you already have the exact 55-inch LCD panel model selected, or should the controller board be chosen based on the panel’s interface and timing requirements? Best regards Mykola
