FAQs

1. Where is your manufacturing facility located and what is your monthly production capacity for the Guition ESP32 display module?

Our primary manufacturing facility is located in Shenzhen, China, where we maintain a stable monthly production capacity of over 50,000 units for the Guition ESP32 display module series. By centralizing our SMT assembly and LCD bonding processes, we ensure rigorous oversight of every ESP32-S3R8 core integration. For bulk orders, our typical lead time ranges from 15 to 25 business days, depending on the specific volume and any requested hardware customizations. We welcome both on-site factory audits and third-party inspections to verify our infrastructure and lean manufacturing standards. Feel free to contact our sales team to schedule a virtual tour of our production lines or to request a factory profile.
2. What is your Minimum Order Quantity (MOQ) for the Guition ESP32 display module, and do you support custom branding?

Our standard Minimum Order Quantity (MOQ) for the Guition ESP32 display module starts at just 100 units for stock models like the ESP32-4827S043N. For large-scale B2B clients requiring custom branding, logo silk-screening, or tailored firmware pre-loading, the MOQ typically increases to 500 or 1,000 units to cover setup costs. We provide flexible sample kits for initial prototyping to help your engineers validate the 480x272 resolution and MCU performance before committing to mass production. Our tiered pricing structure rewards larger volumes, offering significant cost savings for orders exceeding 5,000 pieces. If you have specific hardware modification needs, our engineering team can provide a feasibility report within 48 hours.
3. What certifications does your factory hold to ensure the Guition ESP32 display module meets international regulatory standards?

Every Guition ESP32 display module is manufactured in compliance with strict international quality and safety regulations, holding official CE, RED, and FCC certifications. These certifications guarantee that our modules meet the electromagnetic compatibility and radio frequency standards required for legal sale and operation in European and North American markets. Specifically, the integrated ESP32-S3R8 dual-core MCU is tested to ensure stable Wi-Fi and Bluetooth connectivity without interfering with other industrial equipment. Beyond product-level certification, our factory follows ISO 9001 management protocols to maintain consistency across every production batch. Documentation and full test reports are available upon request for your compliance filing. You can download our latest certification pack from the resources section.
4. How do you guarantee the reliability and aging performance of your LCD modules during the mass production process?

We implement a 100% triple-stage inspection process for every Guition ESP32 display module to eliminate potential defects before they reach the customer. This includes an automated optical inspection (AOI) of the PCB assembly, a functional test of the 8MB PSRAM and 16MB Flash, and a mandatory 24-hour high-temperature aging test for the backlight and LCD panel. Our quality control team monitors the 30,000 to 50,000-hour rated backlight lifespan to ensure long-term durability in industrial HMI environments. By maintaining a factory defect rate below 0.3%, we provide our B2B partners with the reliability needed for critical medical or smart home control panels. Our detailed Quality Assurance (QA) manual is available for review by your procurement department.
5. What are the key factors to consider when choosing a professional manufacturer for ESP32-based HMI display modules?

Evaluating a professional manufacturer requires looking beyond price; one must assess R&D depth, supply chain stability, and technical support capabilities. A top-tier provider should offer comprehensive documentation for development in Arduino IDE, ESP-IDF, and MicroPython, ensuring your engineering team can utilize the full 240MHz frequency of the ESP32-S3 core. Additionally, verify if the manufacturer maintains a safety stock of critical components, like the 4.3-inch LCD panels, to prevent project delays during global chip shortages. Direct manufacturers should also offer customization services, such as high-brightness variants for outdoor use or capacitive touch integration. Selecting a partner with proven experience in HMI solutions ensures your product remains competitive and supported throughout its entire lifecycle.
