# WebUSB
|
|
|
|
WebUSB is an emerging web standard that allows to access @boardname@ from web pages.
|
|
It allows for a **one-click download** without installing any additional app or software! It also allows to receive data from the @boardname@.
|
|
|
|
## Support
|
|
|
|
* Chrome 65+ browser for Android, Chrome OS, Linux, macOS and Windows 10.
|
|
|
|
## Prepare your @boardname@
|
|
|
|
Make sure that your @boardname@ is running version **0249** or above of the firmware. Upgrading is as easy as dragging a file and it takes a few seconds to get it done.
|
|
|
|
* [Check out the instructions to check and upgrade your @boardname@.](/device/usb/webusb/troubleshoot)
|
|
|
|
## Pair your @boardname@
|
|
|
|
Here are the steps on the supported browsers:
|
|
|
|
* connect your @boardname@ to your computer with the microUSB cable
|
|
* open a project.
|
|
* open the gearwheel menu and select **Pair device**
|
|
* click on the **Pair device** button and select **BBC micro:bit CMSIS-DAP** or **DAPLink CMSIS-DAP** from the list.
|
|
|
|
If you don't see any devices in the list and @boardname@ has the right firmware (**0249** or above), you can create a [support ticket](https://support.microbit.org/support/tickets/new) to notify the Micro:bit Foundation of the problem. Skip the rest of these steps.
|
|
|
|
## One-click Download
|
|
|
|
Once your @boardname@ is paired, MakeCode will use WebUSB to transfer the code without having to drag and drop. Happy coding!
|
|
|
|
## Console output
|
|
|
|
MakeCode will be able to "listen" to your @boardname@ and display the console output.
