Set the angle of the Servo which controls the window to 90°:

| Servo for window | PLUS Mainboard|
| :--: | :--: |
| Brown line | G |
| Red line | V |
| Orange line | S（10） |

![](media/image-20250417105156944.png)

Wire up as shown in the picture and upload the code to the expansion board. Install the Servo after it automatically turn to 90°。

Servo calibration requires uploading code, please refer to the corresponding course (Arduino or Scartch) to install the programming software and upload the servo code of the course you are using.
