The Logickeyboard ASTRA 2 Backlit Keyboard for Blender 3D on Windows features a 104-key US English layout that includes a full-sized F-row and multimedia keys, as well as colour-coded and labelled shortcut keys with graphical commands. Thanks to five levels of dimmable backlighting, the ASTRA may be used in a variety of lighting conditions, from bright to dark and day to night. Also featured is one USB 3.0 Type-A port, which may be used to connect a mouse, contour shuttle, or USB dongle. Connectivity with your host system is achieved using a 1.8m cable with two separate USB Type-A connections. Use the grey connector to power the keyboard, and use the black connector for the USB hub.
