On the lateral edges of the device the stereo speakers and the microphone are placed. On the front edge there are volume buttons and a mute mode switch. Here is also a grid for the air flow from the cooling system, which we will discuss later. On the rear edge there are L1, L2, R1, R2 buttons. Pressing stroke is short and accurate. During playing process these buttons are normally placed under your index fingers. We tested tens of various versions of trigger buttons layout, but have eventually found the solution shown in the sketch as the most convenient.
Also, the rear edge has the universal button for powering on and switching between OSes.
In the center of the rear edge a USB-C 3.1 port is placed. We haven't implemented the 3,5mm audio jack for several reasons. Hence we put a special 3,5mm-USB-C tiny adaptor in the box together with the device. Above the rear edge is the special port combining MicroSIM and MicroSD functions. The latter supports all existing memory cards of such type, up to 512Gb. Taking a look at the bottom of device, we can find the main camera, a flashlight LED, and the grid for the air flow towards the active cooling system. The front side includes a standard set of elements: ambient light sensor, proximity sensor, front camera, main screen, and the call speaker. By sliding the device out you will find an additional display, analog sticks, D-Pad, game action buttons, Start, Select, a button to switch off the additional display, and a button to switch between control modes Xinput-Mouse Emulation. All necessary included and nothing extraneous.
