基于 ESP32-S3 的开源圆屏电子徽章，面向日常佩戴与社团展示。用静态或动态壁纸表达个人喜好，通过触摸切换协会名片和小应用，也可以通过电脑或无线连接管理内容。
圆屏亮屏实物 · 计协图案
 侧边按键与边框 |  侧面轮廓 |
照片展示外观与亮屏效果，点击可查看原图；设计版本与验证状态见下方版本表。
可以做什么
- 壁纸与名片：静态图片、EAF 动态壁纸、协会名片，支持触摸浏览和切换。
- 内容管理：通过 USB 或本地 HTTP 上传壁纸，支持 Wi-Fi、BLE 连接管理；电脑端提供原生 NBTCA Badge TOOL。
- 日常交互：亮度设置、姿态与唤醒交互、可选 FPS 显示。
- 小应用：Grok 表情、MC 二维地图、奶蛙矿工、重力小球，以及测试版中的 FluidBox、TimeTiles 和 BLE 心率。详见应用说明。
GIF/视频需先在电脑端转换为 EAF，设备不直接播放 GIF/视频。OTA 与 BLE 传图尚未提供；功能适用版本及待测项见已知问题。
快速入口
| 你想做什么 | 从这里开始 |
|---|---|
| 已有设备，安装或使用固件 | 正式固件、测试固件、安装步骤、无线与壁纸管理 |
| 自己制作一块 CABadge | V2.1 PCB、BOM 与采购资料、V11 外壳与装配、完整复刻流程 |
| 查看单个应用源码 | 应用源码目录：宝可梦、TimeTiles、Grok、MC 实时地图，各自单独保存 |
| 修改源码或参与开发 | 构建环境、开发约定、界面架构 |
版本与资料对应
固件、PCB 与外壳独立编号，请按用途选择配套文件。
| 资料 | 当前版本 | 下载或说明 |
|---|---|---|
| 正式固件 | v1.2.0 / 7.9.16-eaf-transition | 正式 Release，工作台默认安装此版 |
| 测试固件 | v1.3.0-rc.1 / 7.9.23-timetiles-fix | 测试 Release，新功能仍有待测项 |
| 公开源码 | 7.9.23-timetiles-fix | main 分支；自行编译 |
| 当前 PCB | V2.1 GEK100 / 星火计划 | 工程说明：嘉立创EDA原生重画版（2026-10-27）与 KiCad 原工程（2026-10-20），两者不自动同步 |
| 配套外壳 | V11 一体杯壳 + V11_Button_R2 | 打印件与装配、SolidWorks / STEP；仅 Cup + Button，按键专项待验证 |
| 历史硬件 | V1 首板 c7c59dff，仅 KiCad | V1 归档；冻结制造包属于此版 |
自行编译请使用 main。 v1.3.0-rc.1 标签的自动 Source code (zip) 是旧源码快照，与其 7.9.23 固件附件不对应；下载说明解释各文件的用途。
首板 c7c59dff 的实测证据见首板测试记录。V2.1 新增电源与机构、R2 按钮，以及测试固件的部分交互和长稳仍需分项验证；照片、构建或 CAD 检查不代表这些项目已全部通过。

如何开始复刻
- 选定版本：从上方表格分别选择 PCB、外壳与固件。
- 准备器件和板子：按BOM 说明核对采购，从所选 PCB 工程导出并检查制造文件。
- 焊接与上电：按分阶段检查表调试；V2.1 新增电路的检查要求见完整复刻说明。
- 安装固件：按烧录步骤核对版本、备份需要的数据并安装；已有同版设备可从这一步开始。
- 验证与装配：检查显示、触摸、壁纸及连接，再按外壳装配说明完成组装。
BOM 保留 DRAFT 状态；V2.1 尚未附配套制造 ZIP，需从实际选用的工程导出。V1 冻结制造包不能用于制作 V2.1。具体器件、打样、分区及升级注意事项见复刻与安装。
继续开发
板端使用 ESP-IDF / PlatformIO 与 LVGL 9.4.0，当前构建流程面向 Windows、Python 3.10+ 和 PowerShell 7。环境由 tools/bootstrap.ps1 安装；CABADGE_BUILD_ROOT 可配置工具目录，默认 F:\CABadgeBuild。详细操作见构建说明与开发约定。

Questions
What parts does the CABadge V2 1 use?
110 parts, built around the ESP32-S3R8, W25Q128JVSIQ, SC7A20TR and SGM62117XTGH10G/TR. 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 CABadge V2 1 KiCad files?
From the nbtca/CABadge repository on GitHub, at the commit this page was made from: the board is hardware/pcb/current/kicad/CABadge_V2_1.kicad_pcb and its schematic hardware/fabrication/JXBadge_EVT_20260909_c7c59dff/verification/source/Controls_Test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CABadge V2 1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
