Adding WAN port
Adding a second Wi-Fi antenna Mod
The board cut section the track going to the built-in antenna (coil on the board), and part of a track udischy in Wi-Fi module and add a screen between the connector / cable external antenna.
Adding LED Mod
D2 - WPS D4 - second USB port D10 - ? (can be: WAN port on CPU) |
Adding second USB port Mod
Need to unsolder not getting the circuit elements, such as, USB port, LED (D4), circuitry for power supply. This action turns the device D1 โ D2
Adding WAN port Mod
The board can be arranged WAN port (P4).
Need elements:
- P4 Ethernet port RJ45 1X1 connector without shield
- T2 Single 10/100 Base-tx Lan Magnetic: 12ps6121c.pdf
- R196, R197, R201, R202 75 Ohm 0805 size smd resistor
- ะก136 Electrolytic capacitor (I used 220uF*16V)
- U14 Unknown IC (just short circuit pads 3 & 5)
Adding WPS button Mod
The board involves the installation of a button (SW3) and LED (D2), it is necessary to check.
