Adding additional hardware and software for a fully functional core system

The final step in making your BeagleBone Black really useful is to add a wireless LAN interface. This will allow you to control your robotic projects remotely without having a wired LAN cable. It is very straightforward, but there is one slight challenge. Adding a WLAN device might cause your BeagleBone Black to draw in more current than a USB power supply can provide, and your board will stop, that is, the blue light will no longer flash like a heartbeat.

To avoid this problem and provide additional capability to add more devices, you'll need to add a powered USB hub to your BeagleBone Black. This is a USB hub that is powered by an external power supply, not the BeagleBone.

Once you have this device connected to a power supply and to your BeagleBone Black, you can now connect your WLAN device. There are many different WLAN devices; you'll have to follow the instructions for your specific device. See instructions are very simple.

Once you are connected via LAN, you can access the BeagleBone Black wirelessly via SSH and VNC viewer, controlling your robotic projects without limiting their movement.
