Cortex-M33大小核架构，大核主频高达240MHz，性能强劲。芯片集成蓝牙5.3、8MB PSRAM和板载16MB Flash。</span></p> <p> </p> <p><strong><span style="font-size:14pt">屏幕</span></strong></p> <p><span style="font-size:14pt">配备1.33英寸TFT显示屏，虽然是小尺寸屏，但分辨率高达240×240，画面显示细腻。</span></p> <p><span style="font-size:14pt"><img src="https://image.lceda.cn/oshwhub/pullImage/9f9a873a41474cf2b4d4c398f2f21969.png"></span></p> <p> </p> <p><strong><span style="font-size:14pt">音频系统</span></strong></p> <p><span style="font-size:14pt">采用NS4150B功放 + 红米Note扬声器 + 共鸣腔设计，外放效果接近手机。</span></p> <p><span style="font-size:14pt">第一版共鸣腔设计：出音孔较大，声音尖锐，低频不足，但通过胶带封堵出音孔，低频有显著提升，音质接近手机（<a href="https://www.bilibili.com/video/BV172YPzVE5o/" target="_blank">详见演示视频</a>）。</span></p> <p><span style="font-size:14pt"><img
