# 升级旧款 Bittle/Bittle X

旧款 Bittle/Bittle X 型号具有不同的硬件配置。下表显示了不同型号需要升级哪些组件才能与机器臂扩展模块（铝合金舵机）兼容：

* <mark style="color:red;">红色</mark>表示该部件必须升级
* <mark style="color:green;">绿色</mark>表示该部分可以继续使用用
* <mark style="color:blue;">蓝色</mark>表示需要调整电路板布线和其它配置。

最简单的解决方案是购买最新的组件以匹配Bittle X+Arm的配置。我们会提供折扣组合套件以帮助您完成设备升级。

以下说明将指导您重新配置产品**Bittle X V1** ( BiBoard V0) 以兼容机器臂扩展模块。您必须完成以下所有步骤。

## 1. BiBoard V0 重新配置硬件

机械臂的铝合金舵机需要更多的电流。为了绕过保险丝（标记为 **X30** 或 **X70**），您必须直接焊接其两端。

## 2. 固件升级

### Petoi桌面应用程序

您需要使用桌面应用程序中的[**固件上载**](https://docs.petoi.com/chinese/zhuo-mian-ying-yong/gu-jian-shang-zai)来升级固件，请设置以下选项：

产品： **Bittle X+Arm**

主板型号： **BiBoard V0\_\***  （根据机器人实际的主板型号选择相应选项）

模式： **标准**

### Arduino IDE

或者您也可以通过在Arduino IDE中激活以下宏定义语句，[编译上传](https://docs.petoi.com/chinese/arduino-ide/wei-biboard-shang-chuan-cheng-xu)程序到BiBoard主板。

```cpp
#define BITTLE
#define BiBoard_V0_*   //根据机器人实际使用的主板型号来激活代码中相应的宏定义语句
#define ROBOT_ARM
```

## 4. 关节校准

机械臂需要校准才能正常工作。详细步骤请参考[相应章节](https://docs.petoi.com/chinese/kuo-zhan-mo-kuai/ji-xie-bi#jin-ru-jiao-zhun-zhuang-tai)的说明。

## 5. 手柄控制器（可选）

您可以在我们的官网选购 [Micro:Bit游戏手柄](https://docs.petoi.com/chinese/kuo-zhan-mo-kuai/microbit-you-xi-shou-bing#kong-zhi-bittle-xarm-dai-ji-xie-bi)，它可以提供直观且迅速的机器人控制。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.petoi.com/chinese/kuo-zhan-mo-kuai/ji-xie-bi/sheng-ji-jiu-kuan-bittlebittle-x.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
