It was always interesting to find out what in the middle of Amazon button. This simple device allows you to make a purchase with the click of a button. It turned out to be not quite true. But it does not matter. In the end, I bought this device, with only one purpose - to disassemble.
This is a one-time device in which no one is going to change the battery. Therefore, the housing of the device is glued.
But there are three screws under the top sticker.
The first thing you will see.
And if you unscrew the three top screws, then:
And on the other side.
Surprisingly, the device also has a microphone, which fell off at the beginning.
WiFi antenna - classic design.
One DC-DC converter.
Do not have time, yet, to find out what is what on this board.
But it looks like a microcontroller.
WiFi module (Intell?) and memory chip.
I think I broke the microphone when I opened the case. This has never happened before, but maybe it’s even good for the future.
It is a very simple design and well done. The only thing that surprised me was the WiFi module. I expected something cheap, like ESP8266.
This is always the place to be surprised.
