A-Pocket - 基于全志A133的掌上终端

渲染.5.5

视频介绍：【开源】 自 制 手 机 ：【一】PDA？_哔哩哔哩_bilibili

虽然是奔着DIY手机去的，不知咋的就做成PDA了（

由于屏幕特殊，性价比极低，不建议复刻除核心板外的其他东西。

硬件组成

  • 核心板：板载全志A133邮票孔模块、USB-OTG、USB-Debug、带MIC的3.5mm耳机接口、扬声器接口、电池接口、MPU6050、RTC等，单板即可满足正常工作。另外由板对板引出显示屏接口和USB接口供拓展。未引出A133提供的摄像头接口。
  • 拓展板：板载LCD背光电路、USB5V的DC-DC升压电路和USB-HUB电路等。
  • 散热：背壳贴石墨烯，由导热硅垫传热

软件组成

核心模组厂商提供了安卓10和Ubuntu的镜像，要适配屏幕只需要简单修改设备树的配置文件即可。

缺点

屏幕性价比低，屏占比低，核心模组也比较贵

板对板连接导致厚度大，扬声器音质很烂

待改进

改用量产的手机MIPI屏幕，但需要学写驱动（泪目

主控想改用RK3399或RK3588，但价格~~
