はじめに

This TL-WR802N router is designed for mobile use, with speeds up to 300 Mbps. It uses a micro USB port for power only, and only has 1 ethernet port.

Inside the device contains:
Speeds up to 300 Mbps; 2x2 MIMO antenna setup; 5 modes which can turn it into a WiFi extender, or a Wi-Fi client to connect wired only devices to Wi-Fi.
On the outside:
Green LED indicator
10/100 Ethernet port; can be used as a WAN or LAN
Micro USB for power
Recessed Reset Button

On the top of the router, there is a blue panel that is the case. It is held on by clips, holding it in place.
The top panel can be removed by using a small flat bladed screwdriver and inserting it into the gap between the case and the panel itself.
You have to use a little force, but not too much force as you'll break those clips!

Once the cover is loose, the cover can be removed, revealing the router's main circut board.

With the top panel removed, we can now see the internal components.
A spudger was used to lift the circuit board out of the case.
There was no room to wedge the board out of the case, so one of the antennas was used with the top of the spudger to lift the board out of the case.

On the front of the board:
Qualcomm Atheros QCA9533-AL3A SoC
Running at a speed of 560 MHz
Uses the MIPS 24Kc architecture
Contains an integrated Ethernet switch and wireless radio built in.
2 soldered antennas that allows a MIMO configuration of 2x2:2.

And that's It!
The router in this teardown is v1.0. There is another version of the same router, called V2.0, which is virtually identical, however it will only accept firmware that was sold in that country.
For a very small device it can do alot! But it can do more if the OpenWrt/LEDE firmware was ported over.
Unfortunately, due to the limited amount of memory and RAM, OpenWrt and LEDE may not work as expected, as it expects more memory and RAM, therefore you can't turn it into say a OpenVPN client.
