# 6.11 Spraying Configuration

This section allows you to configure spraying-related parameters such as minimum, and maximum PWM values, RC switch, etc.

<figure><img src="/files/jD40B4M9S8wc762gzkd8" alt=""><figcaption><p>Spraying Configuration</p></figcaption></figure>

* **Enable Spraying: Sprayer enable/disable:** Allows you to enable or disable the sprayer.
* **RC Switch:** Set the value of the RC switch in between 0 to maximum of 102.
* **BRD PWM Count:** Controls the number of PWM-enabled Flight Management Unit (FMU) outputs. All unassigned pins on the board can be used for GPIO.

| Value | Meaning    |
| ----- | ---------- |
| 0     | No PWMs    |
| 1     | One PWMs   |
| 2     | Two PWMs   |
| 3     | Three PWMs |
| 4     | Four PWMs  |
| 5     | Five PWMs  |
| 6     | Six PWMs   |
| 7     | Seven PWMs |
| 8     | Eight PWMs |

{% hint style="info" %}
**Note:** This parameter is for advanced users. Controls number of FMU outputs which are setup for PWM. All unassigned pins can be used for GPIO.
{% endhint %}

* **SERVO9 Function \[Aux 1]**
  * **PWM Min:** Minimum PWM pulse width in microseconds. Typically 500 is lower limit, 1000 is neutral and 2000 is upper limit.
  * **PWM Max:** Maximum PWM pulse width in microseconds. Typically 800 is lower limit, 1500 is neutral and 2000 is upper limit.
* **SERVO10 Function \[Aux 2]**
  * **PWM Min:** Minimum PWM pulse width in microseconds. Typically 500 is lower limit, 1000 is neutral and 2000 is upper limit
  * **PWM Max:** Maximum PWM pulse width in microseconds. Typically 800 is lower limit, 1000 is neutral and 2000 is the upper limit.

The parameters will be sent to the device after clicking on the "Update" button.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://aerogcs-docs.aeromegh.com/5-rpa-configuration/6.11-spraying-configuration.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.
