# DFRobot 行空板 K10
## 按键配置
* A：短按-打断/唤醒，长按1s-音量调大
* B：短按-打断/唤醒，长按1s-音量调小
## 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 行空板 K10
```
**修改 psram 配置：**
```
Component config -> ESP PSRAM -> SPI RAM config -> Mode (QUAD/OCT) -> Quad Mode PSRAM
```
**编译：**
```bash
idf.py build
```
