The YVT021WV-C01 offers strong environmental adaptability, with an operating temperature range of -20°C to 70°C and a storage temperature range of -30°C to 80°C, suitable for different working scenarios. It passes strict reliability tests, including 120 hours of high-temperature (80°C) and low-temperature (-30°C) storage, 120 hours of high-temperature (70°C) and low-temperature (-20°C) operation, and 10 thermal cycles (-20°C ↔ 25°C ↔ 70°C) without functional or appearance abnormalities. Additionally, the module’s glass display panel and soft polarizer require careful handling—avoid mechanical shocks, clean only with isopropyl or ethyl alcohol, and maintain anti-static measures (like grounding the body and tools) during assembly to prevent damage
The YVT021WV-C01 offers multiple customization options to meet diverse application needs:
