# 特性
* 使用PDM麦克风
* 板载 OV3660 摄像头
## 按键配置
* BOOT：短按-打断/唤醒
## 编译配置命令
**配置编译目标为 ESP32S3：**
```bash
idf.py set-target esp32s3
```
**打开 menuconfig：**
```bash
idf.py menuconfig
```
**选择板子：**
```
Xiaozhi Assistant -> Board Type -> DFRobot ESP32-S3 AI智能摄像头模块
```
**修改 psram 配置：**
```
Component config -> ESP PSRAM -> SPI RAM config -> Mode (QUAD/OCT) -> Octal Mode PSRAM
```
**修改 WiFi 发射功率 为 10：**
```
Component config -> PHY -> (10)Max WiFi TX power (dBm)
```
**编译：**
```bash
idf.py build
```
