# Common Components

***

## USB Stuff

* ### USB-PD Trigger Boards

* 5V Trigger Board - <https://u.cray.io/5v-trigger-board> \[Amazon]

  This board can accommodate other voltages but I only use it for 5V since you need to bridge pads to get the voltage you want. Bridge the following pads to get 5V (and of course verify with multimeter):

* 9V, 12V, 15V, 20V Trigger Boards - <https://u.cray.io/pd-trigger-boards> \[Amazon]

  I prefer these boards when I need something other than 5V as they work out of the box

### USB-C Connectors

* Male/Female - <https://u.cray.io/usb-c-connectors> \[Amazon]

### USB-C Power Meter

* USB-C Power Meter - <https://u.cray.io/usb-c-power-monitor> \[Amazon]

### USB-PD Power Supplies

* Mackertop 100W - <https://u.cray.io/usb-pd-power-mackertop> \[Amazon]

* Anker 100W - <https://u.cray.io/usb-pd-power-anker> \[Amazon]

  This supply supports: 5V3A / 9V3A / 15V3A / 20V5A (**Note**: No 12V support!)

### USB-C Cables

* Anker Cables - <https://u.cray.io/usb-c-cable-anker> \[Amazon]

  All around great cables - really can't go wrong with these.
* AUFU Magnentic USB Cables - <https://u.cray.io/usb-c-cable-aufu> \[AliExpress]

  These cables are awesome and allow you to quickly attach and detach to your devices. They support USB-C, MicroUSB, and Lightning connector. You can purchase additional inserts to support several devices. I've started using these everywhere.

# 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://www.cray.io/projects/common-components.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.
