- 当前安装位置适合作为样机默认布局，尚未针对最终外壳进行结构定型。
安全及首次上电检查
- 只能使用带保护板的单节锂电池；
- 通电状态下禁止插拔墨水屏 FPC；
- 安装屏幕前，确认 J3 的 6、7、8、17 脚均为 GND，并用实物再次核对 连接器接触面和 Pin 1 方向；
- 第一次上电使用带限流功能的实验电源，先确认 3.3 V 正常，再安装屏幕；
- 屏幕刷新时通过 TP5～TP8 检查 GDR、RESE、PREVGH 和 PREVGL；
- 墨水屏高压电路采用 SSD1677 参考拓扑，C12～C23 必须使用 X5R/X7R、 耐压不低于 25 V 的电容。

Questions
How big is the Ai mobile reader PCB?
It measures 58 × 102 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ai mobile reader use?
79 parts, built around the ESP32-S3-WROOM-1-N16R8, BQ24074RGTR, TPS63031DSK and MBR0530. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ai mobile reader KiCad files?
From the beishan/ai-mobile repository on GitHub, at the commit this page was made from: the board is hardware/ai_mobile_reader.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ai mobile reader design in my own project?
Its repository states no licence, so its author keeps all rights: ask beishan before reusing the design.
