设计工程师的关键差异化者
(1)双接口灵活性
支持SPI(4线)和8位8080平行接口,用于与ARM Cortex-M/R,Raspberry Pi Pico和其他嵌入式平台无缝集成。
专用的恒电流背光驱动销(LED+/LED-)将寿命扩展到40,000小时(第8页)。
(2)坚固的结构
通过-30°C〜80°C的存储,±8KV ESD保护和60厘米的降落测试(IEC 60068-2-32符合±8kV)。
可选的化学加强盖玻璃(≥6H硬度),≥85%的光传输(第5页)。
(3)精确的光学性能
活动区域:22.7×42.72毫米|像素螺距:0.1335毫米| RGB垂直条纹矩阵。
由工厂校准的白点(CIE 1931 x = 0.302/y = 0.325)用于医疗/工业色彩准确性(第12页)。
工程资源
STM32/Arduino平台的预测试初始化代码(第18-19页)。
提供机械图,时序图和光学测试报告(BM-7标准)。
带有OCA层压板的可选多点触摸溶液(CST816D IC)。
欧盟/美国合规性保证
◾遇到ROHS(EU 2015/863),到达SVHC和无卤素指令。
◾包装符合欧盟2025/40的可回收性要求(有效2026年)。
