接线说明
通过天空端模块背面的 4 个 M2 螺丝孔将模块固定于飞行器或其他设备上，并参照下图连线。
注：
- 用户需自备电烙铁和焊锡进行连线。焊接时请确保焊点牢固且不会出现开路或短路
-
本产品发热较大，请勿在请勿在无外部散热的条件下直接触碰
-
请勿在无外部散热的环境下长时间使用该模块，否则可能会造成产品损坏
-
安装天空段天线时应注意两根天线圆柱体部分至少间隔 100mm，以达到最佳通信效果；同时尽量远离金属或碳纤维结构件，并确保飞行中天线不会被遮挡
固件升级
请按照以下步骤升级天空端模块：
1. 使用天空端升级线连接遥控器 AUX 接口与天空端模块 UART1 接口，使用Type-C 数据线连接遥控器与 PC
2. 开启遥控器，将天空端模块上电
3. 打 开 CwGcs2BaseMainPC 软 件， 连 接 遥 控 器 后 将 辅 助 串 口 模 式 设 为CDC<=>AUX; 4. 打开 CwGcs2RoverPC 软件，打开点击“打开固件”，选择天空端固件文件
5. 点击“开始升级”直至软件下方提示升级成功
