Inside the retail package, we find a product sheet and the Optimus Mini Three itself. There is no installation / user manual or software disc included. The included product sheet directs you to Art. Lebedev's website for all of this.
Here we see the Mini Three unit. Each of the three keys is 32 x 32 mm in size with a 20 x 20 mm viewable area at a resolution of 96 x 96. This is a little larger than the standard keys on the Optimus Maximus, which are 20.2 x 20.2 mm in size with a viewable area of 10.1 x 10.1 mm at a resolution of 48 x 48 mm. Each of the three keys arrived with a protective covering to prevent any scratching during shipping / handling.
The Mini Three is configurable to function both horizontally and vertically, so you can use whatever orientation works best for you. On the bottom of the unit are two rubber feet to hold the Mini Three securely in place on your desk.
That's pretty much it. Up next, software installation and usage...
