+## 四、BLE 蓝牙资源消耗专项
+
+| 组件 | 大小 | 说明 |
+|------|------|------|
+| libbt.a | 193.7 KB | Bluedroid 协议栈 |
+| libbtdm_app.a | 71.5 KB | BLE 控制器固件 |
+| libcoexist.a | 4.9 KB | WiFi/BLE 共存 |
+| libbtbb.a | 3.4 KB | BLE Baseband |
+| libesp_phy.a | 3.1 KB | PHY (部分) |
+| **BLE 合计** | **~276.6 KB** | 约占固件总大小 20% |
+
+**BLE 内存优化配置**：
+- `CONFIG_BT_ALLOCATION_FROM_SPIRAM_FIRST=y`：BLE 动态分配优先使用 PSRAM，减少内部 SRAM 压力
+- BLE DIRAM 占用仅 ~15 KB（得益于 PSRAM 分流）
+
+---
+
+## 五、LVGL 图形库资源消耗专项
+
+| 项目 | 大小 | 说明 |
+|------|------|------|
+| LVGL 核心库 | 322.9 KB | 控件、渲染、动画等 |
+| LVGL Port | 3.9 KB | ESP-IDF 适配层 |
+| UI 图片资源 (Flash) | ~333 KB | 内嵌在 libmain.a 中的 PNG/图标 |
+| LVGL DIRAM (.bss) | 65.1 KB | 帧缓冲、对象树等 |
+| **LVGL 合计** | **~326.8 KB** | 约占固件总大小 24% |
+
+---
+
+## 六、功能模块清单
+
+| 模块 | 状态 | 资源影响 |
+|------|------|----------|
+| LVGL UI (三界面) | 已启用 | Flash ~327 KB, DIRAM ~65 KB |
+| BLE GATT Server (图片传输) | 已启用 | Flash ~277 KB, DIRAM ~15 KB |
+| SPIFFS 文件系统 | 已启用 | Flash ~23 KB |
+| JPEG 解码 | 已启用 | Flash ~6.3 KB |
+| LCD ST77916 (QSPI) | 已启用 | Flash ~5.2 KB |
+| CST816S 触摸 | 已启用 | Flash ~1.3 KB |
+| PWM 背光 | 已启用 | Flash ~5.1 KB |
+| 电池 ADC 监控 | 已启用 | < 1 KB |
+| 按键驱动 | 已启用 | < 1 KB |
+| 低功耗管理 (DFS + Light Sleep) | 已启用 | Flash ~2.8 KB |
+| WiFi | 未启用 | 仅链接 58 B (stub) |
+| ~~温湿度传感器~~ | **已移除** | — |

+
+## 七、资源余量评估
+
+### 7.1 关键资源余量
+
+| 资源 | 当前占用 | 总量 | 剩余 | 余量评估 |
+|------|----------|------|------|----------|
+| **内部 SRAM (DIRAM)** | 180.6 KB (54.1%) | 333.8 KB | **153.2 KB** | 充裕，可支撑更多功能 |
+| **IRAM** | 16.0 KB (99.99%) | 16.0 KB | **1 B** | 已满，但正常（ESP-IDF 自动管理溢出到 Flash） |
+| **App Flash** | 1,359 KB (33%) | 4,096 KB | **2,737 KB** | 非常充裕 |
+| **总 Flash** | ~6 MB (分区) | 16 MB | **~10 MB** | 极其充裕 |
+| **PSRAM** | 运行时动态分配 | 8 MB | ~7.5+ MB | 极其充裕 |
+
+### 7.2 IRAM 满载说明
+
+IRAM 99.99% 是正常现象：
+- ESP-IDF 的链接脚本会自动将溢出的 IRAM 代码放到 Flash 中执行
+- 只有标记为 `IRAM_ATTR` 的关键中断处理函数才必须在 IRAM
+- 不影响正常运行，无需优化
+
+### 7.3 运行时内存估算（满负荷）
+
+| 项目 | 预估消耗 | 来源 |
+|------|----------|------|
+| FreeRTOS 任务栈 (5-6个任务) | ~30 KB | DIRAM 堆 |
+| LVGL 帧缓冲 (双缓冲) | ~43 KB | PSRAM |
+| LVGL 对象树/样式 | ~20 KB | DIRAM 堆 |
+| BLE 连接管理 | ~10 KB | PSRAM (优先) |
+| JPEG 解码临时缓冲 | ~15 KB | 堆 (临时) |
+| SPIFFS 缓存 | ~4 KB | 堆 |
+| **合计** | **~122 KB** | |
+| **DIRAM 堆剩余** | **~153 KB** | 满足需求 |
+
+---
+
+## 八、总结
+
+**N16R8 模组资源完全满足当前项目需求**：
+
+1. **Flash (16MB)**：固件仅用 1.36 MB，SPIFFS 2 MB，大量空间可扩展 OTA 或增加图片存储
+2. **内部 SRAM (512KB)**：DIRAM 占 54%，剩余 153 KB 足够运行时动态分配
+3. **PSRAM (8MB)**：BLE 动态内存优先使用 PSRAM，有效降低内部 SRAM 压力，剩余 7+ MB
+4. **BLE 影响可控**：BLE 增加约 277 KB Flash + 15 KB DIRAM，对 N16R8 影响微乎其微
+
+**优化建议**（可选）：
+- 如需进一步减少 Flash 占用，可考虑压缩 UI 内嵌图片资源（当前 ~333 KB）
+- 如需启用 WiFi + BLE 共存，DIRAM 仍有足够余量
+- PSRAM 可用于存储更大的 JPEG 解码缓冲，提升图片切换速度
