   * {{ ::raspberry_pi_3.png?100|}}Raspberry Pi 3 Beta microcomputer is available via online stores. (Not to be confused with Raspberry Pi 3 Beta **Plus** - a slightly more powerful version but requiring 3A power and at least the latest Raspbian Stretch OS.) The micro SD that came with the original setup can just be inserted into a newly-ordered Raspberry Pi 3 Model B, and it should be good to go.   * {{ ::raspberry_pi_3.png?100|}}Raspberry Pi 3 Beta microcomputer is available via online stores.

   * {{ ::heatsink.png?80|}}Over time, the heatsink could detach, as its adhesive would dry up. In this case, just remove the heatsink from the box to prevent it from short-circuiting the microcomputer board. The alternative is to use some double-sided, heat-transfering adhesive tape to re-attach the heatsinks. Remember to wipe the surface first before mounting the heatsink.   * {{ ::heatsink.png?80|}}Over time, the heatsink could detach, as its adhesive would dry up.

-  * {{ ::raspbibetawithfan.jpg?100|}} IF you have eLib Box version with a fan that draws its power from the Raspberry Pi board, notice to which pins fan wires are attached to and the colors (red and black) of the wire. Red on Pin 4 (5v power); black on Pin 6 (ground). Just in case the wires get detached from the board, just put them back in. If the fan itself breaks, don't worry too much about it. Just keep it there until you find a suitable replacement.+  * {{ ::raspbibetawithfan.jpg?100|}} IF you have an eLib Box version with a fan that draws its power from the Raspberry Pi board, notice to which pins fan wires are attached to and the colors (red and black) of the wire.
