AtomS3R CAM、AtomS3R M12 是 M5Stack 推出的基于 ESP32-S3-PICO-1-N8R8 的物联网可编程控制器，搭载了摄像头。Atomic Echo Base 是一款专为 M5 Atom 系列主机设计的语音识别底座，采用了 ES8311 单声道音频解码器、MEMS 麦克风和 NS4150B 功率放大器的集成方案。
两款开发版均**不带屏幕、不带额外按键**，需要使用语音唤醒。必要时，需要使用 `idf.py monitor` 查看 log 以确定运行状态。
## 配置、编译命令
**配置编译目标为 ESP32S3**
```bash
idf.py set-target esp32s3
```
**打开 menuconfig 并配置**
```bash
idf.py menuconfig
```
分别配置如下选项：
- `Xiaozhi Assistant` → `Board Type` → 选择 `AtomS3R CAM/M12 + Echo Base`
- `Partition Table` → `Custom partition CSV file` → 删除原有内容，输入 `partitions_8M.csv`
- `Serial flasher config` → `Flash size` → 选择 `8 MB`
按 `S` 保存，按 `Q` 退出。
**编译**
```bash
idf.py build
```
**烧录**
将 AtomS3R CAM/M12 连接到电脑，按住侧面 RESET 按键，直到 RESET 按键下方绿灯闪烁。
```bash
idf.py flash
```
烧录完毕后，按一下 RESET 按钮重启。
