  * A Beaglebone Black. The exact revision of the hardware isn't very important, but it should have an ethernet socket.
  * Optionally a plastic or metal case to protect the electronics.

+ * An ethernet cable. Typically these are colour coded either blue or yellow. Either colour will do. If you're using the Wireless version of the Beaglebone Black then you don't need this.
  * Either a 5v power supply with 5.5mm barrel plug, or a miniUSB type B cable (typically supplied with the Beaglebone) and USB to mains adaptor.
  * A microSD card at least 8 gigabytes in size. In tests Sandisk class 10 works well. Prefer smaller but faster I/O rating to larger but slower.
  * A microSD card adaptor for your laptop or desktop system, so that you can copy the disk image to the card.

This will be its main drive, with the internal EMMC not being used at all. For the Beaglebone Black Wireless ssh back in on the usual 192.168.7.2 address with the USB cable connected so that your wifi login parameters can be set.
 
 There are many apps available within the Freedombone system and trying to install them all is probably not a good idea, since this hardware is very resource constrained on CPU and especially on RAM. If the system seems to be becoming unstable and crashing then the most likely cause is running out of RAM, in which case you can try uninstalling some apps. It is possible to monitor RAM usage by logging in with ssh, exiting to the command line and then running the /top/ command.
