# Sandbox Images

Mycroft Sandbox images allow Voice Developers, and Tech Enthusiasts to burn an image to either the included 16GB USB drive or separate drive (user provided) for experimentation and development.

Important notes for use of Mycroft Sandbox images:

* All images are built using Raspberry Pi OS Lite as a base image. 
* There is no WiFi Connect module included. It is recommended to flash these to a USB using the Raspberry Pi Imager. The advanced settings of this tool provides the ability to preset your WiFi credentials when flashing. See the [Raspberry Pi documentation](https://www.raspberrypi.com/documentation/computers/getting-started.html#advanced-options) for more details.
* The default login credentials for all images are the long-standing Raspberry Pi defaults:
  * Username: `pi`
  * Password: `raspberry`

#### [Dinkum Sandbox](https://mycroft.ai/to/mark-ii-sandbox-dinkum/)

Provides a more traditional Linux environment for the same Dinkum software that comes installed by default on all Mark IIs. This is the recommended starting point for new projects and enterprise solutions developing on the Mark II - it’s what we use internally!

#### [Classic Core Sandbox](https://mycroft.ai/to/mark-ii-sandbox-classic-core/)

For those who are familiar with previous versions of Mycroft Core, this is an image with the long standing Mycroft Core software including all of the existing tooling you know and love. Good for those who want to tap into the existing ecosystem of Skills.

It is important to note that the Classic Core software does not provide a polished user experience. There are a range of known bugs and limitations and these are not currently a priority for the internal development team. 

#### [Mark II Hardware Sandbox](https://mycroft.ai/to/mark-ii-sandbox-hardware/)

If you want to start a project from scratch, this comes with all of the drivers and a Hardware Abstraction Layer (HAL) needed to utilize the Mark II hardware, but no other Mycroft software. Perfect for those wanting to utilize the hardware in their own ways. 

This is really the “sand” part of the Sandbox Images, nothing will happen if this OS is used to boot the Mark II - that world is entirely your oyster. We'd love to see all the pearls you create.

#### Compile it yourself

For each Sandbox you can download the pre-built versions above, or fork the repository to compile your own:
