Inside the Avior 8200
Getting into the Avior was pretty straight forward, although we did have to be gentle in case of ribbon cables, which in fact there is one going from the top PCB into the main PCB at the base of the mouse.
Removing the top PCB from inside of the mouse, we found that the DPI buttons are backed with switches we have yet to see. Google-ing mouse switches with a Pi logo reveals nothing, and without pulling them from the PCB to get a part number, that is all we know of these. They do require less activation pressure than say a ZHIJ or TTC switch.
The pairs of buttons on either side of the Avior are backed with these TTC red switches. They are a really good secondary choice for switches, and for buttons that get used much less, are a great economical choice compared to Omron switches.
The left click button is backed with an Omron D2FC-F-7N switch, but the 10M denotes these are ten million click offerings, rather than the basic five million other mice offer. The click function of the scroll wheel uses a brown pad style switch just behind the Omron.
Right in the center of the PCB layout, the laser sensor is placed. Mionix chose the Avago ADNS9800 for the Avior over the 9500 used in the Naos. We are dealing with a top tier sensor now, but in reality, there is very little noticeable difference in the way they track or feel.
To communicate with the PC, the laser sensor, and all the switches, Mionix has thrown in the ARM STM32F103 32-bit processor that runs at 72MHz, and offers 16-bit communication channels. I have to assume that with the lack of a specific memory IC, this is also used for the 128kb of onboard storage.
The right click button also gets treated with the same Omron switch with ten million clicks worth of lifespan.
While you do have a full choice of color options, when the Avior 8200 is initially powered, all of the LEDs are set to green to match the Mionix logo colors. Seen in this image, the center of the scroll wheel is brilliantly lit from the LED.
Even though while using the Avior it is rather tough to see this, the logo is just as brilliantly illuminated at the heel of this mouse. Walking into the office and seeing them both illuminated is nice, especially when it is dark, as these LEDs make the mouse easy to find, and very attractive to look at when the Avior 8200 is not in use.
