UINIO-Monitor 显示屏幕模组

UINIO-Monitor 是一款同时拼接了 0.96 英寸 LCD 显示屏(ST7735,160×80)、0.96 英寸 OLED 显示屏(SSD1315,128×64)、1.3 英寸 LCD 显示屏(ST7789,240×240)、2.4 英寸 LCD 显示屏(ST7789,240×320)、1.69 英寸 LCD 显示屏(ST7789,240×280) 的五合一屏幕驱动电路设计。

设计概要

  1. 采用 FreeCAD 绘制了合理并且美观的板框(长度与宽度均小于或等于 10cmm);
  2. 分别提供有 4 个 1mm 直径螺丝孔,便于安装至其它结构件,快速搭建出产品原型;
  3. LCD 屏幕的外接引脚线序全部保持统一,并且重要的丝印信息会同时标注在 PCB 的顶层与底层;
  4. PCB 板载 0.5mm 间距的 FPC 柔性排线连接器,同时还引出了 2.54mm 间距的直插排针,便于通过杜邦线快速搭建实验电路;
  5. 由于 OLED 屏幕的功耗相对较小,因而采用了 300mA 输出的线性稳压芯片 XC6206P332MR;而功耗相对较大的 LCD 屏幕,则统一采用 ME6211C33M5G-N 线性稳压芯片;

注意事项

  1. 工程的 CAD 目录下,保存的是 FreeCAD 绘制的 PCB 板框草图文件;
  2. 工程的 3D Models 文件夹,保存的是 LCD 和 OLED 裸屏的 3D 模型 FreeCAD 源文件;
  3. 工程的 Reference 目录下提供了裸屏相关的数据手册以及参考原理图;
  4. 0.96 英寸 OLED 显示屏 同时兼容采用 SSD1306 和 SSD1315 两款驱动芯片的屏幕;
  5. 由于 XC6206P332MR 电源正负极反接时,极易导致线性稳压芯片烧毁,所以串联 SOD-323 封装的肖特基二极管防止反接;
  6. 当使用 Arduino 的 U8g2 库驱动 0.96 英寸 OLED 显示屏 的时候,必须焊接上 R20 电阻,而 R19 电阻位置可以留空;

What parts does the UINIO Monitor use?

66 parts, built around the S8050. 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 UINIO Monitor KiCad files?

From the uinika/UINIO-Monitor repository on GitHub, at the commit this page was made from: the board is UINIO-Monitor.kicad_pcb and its schematic UINIO-Monitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the UINIO Monitor design in my own project?

Its repository states no licence, so its author keeps all rights: ask uinika before reusing the design.
