# I/O Connections

Pixy S will be used with the HDMI HYPER QUICK RELEASE V2.0

[HDMI HYPER QUICK RELEASE V2.0](/accessories/quick-release/hdmi-hyper-quick-release-v2.0.md)
{% endcontent-ref %}

HDMI HYPER QUICK RELEASE V2.0 distinguishes itself from the prior version by featuring a USB-C 2.0 signal port connecting directly from Quick Release to the tilt gimbal, along with an Aux port offering optional signals (S1-S4) for user connections to devices like AV signals or camera triggers for expanded functionality. The signal path runs directly from QR to the tilt gimbal, with Pin 1 positioned as the leftmost pin.

| 3   | Signal Hotshoe |
| 4   | GND            |

{% hint style="info" %}

1. **Hotshoe signal**

Signal S6 (SYNC) has a resistance of 220 ohm on the line, so it can only be measured for continuity by measuring the resistance with a value of 220 ohm.&#x20;

2. **USB-C**&#x20;

5V output To enable VBUS on the Pixy S's USB-C connection. Please connect the CC1 to GND on the USB-C male connector via the 5k1 resistor, and then the VBUS will be enable to output the power, Power rate about 5V\@1A. We understand that this is difficult to do on the standard USB-C connector, but it is required if you want to draw power from USB-C on the Pixy S. We have a USB-C board with custom pins; you can buy it to integrate.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.gremsy.com/gimbals/pixy-s/user-manual/getting-started/i-o-connections.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
