Three types of extensions are defined and provided on mBlock 5: devices (hardware support), device extensions, and sprite extensions.

Devices

A device on mBlock 5 and Extension Builder refers to a block set designed and developed for a hardware device and is generally applicable only to that hardware device.

The hardware device described here refers to a single-chip module or microcomputer that is designed with specific connection and communication modes and can perform computing tasks. To put it in another way, a hardware device is a main control board or a hardware product with a main control board.

After you successfully publish a device on Extension Builder, it is displayed in Device Library of mBlock 5.

Example: Halocode

We have developed a device named Halocode for the hardware device Halocode on Extension Builder. The device Halocode is actually a block set developed for Halocode, as shown in the following figure.

After the device Halocode is successfully published, you can find it in Device Library of mBlock 5.

Device extensions

A device extension is a block set developed to enhance the functions of a hardware device. Device extensions can be used to implement the functions of hardware devices or electronic modules that work in combination with them.

After you successfully publish a device extension on Extension Builder, it is displayed in Device Extensions of the extension center on mBlock 5.

Example: Smart Camera for Halocode

To add the device extension, you need to add the device it supports first.

A sprite extension is a non-default block set developed for sprites. Sprite extensions may be block sets for computing or those developed based on Web APIs to implement various Internet-based functions, such as weather information acquisition, face recognition, text translation, cognitive services, machine learning, and drawing.

After you successfully publish a sprite extension on Extension Builder, it is displayed in Sprite Extensions of the extension center on mBlock 5.
