W600 SmartSwitch Teardown: WiFi Switch Quality, Realtek to W600 Transition & T102 w600-v2.0 Boar

  • Good afternoon.

    Recently bought a small amount of WiFi switch for about 1.4 eur.

    It is clearly seen that on https://www.elektroda.com/rtvforum/topic3815120.html - exactly the same boxes and the layout of the board, only the color of the board is light yellow.

    Close-up of a WiFi Smart Switch with exposed PCB and a glowing blue LED.

    The build and soldering quality is disgusting :)

    Disassembly showed that they installed realtek and started installing the w600.

    Circuit board with a WiFi module integrated into an electronic setup.

    Internal board T102 w600-v2.0, goldfinger as wa2, cb2s, wr2s or TYWE3S TYWE2S.

    TX-RX additional boards are not attached to the board, so it is possible not to solder out the board for programming (and it is possible to use it). They are distributed in a 6-pin row cut after VDD and GND.

    Electronic circuit board with wires connected to various components.

    Downloading the firmware to the platform as described in the topic: https://www.elektroda.com/rtvforum/topic3926992.html#20239610

    software: https://github.com/w600/wm_tools

    I used the port speed: 460800

    GPIO Finder will help me set pins:
    "pins": {
    "6": "Btn;1",
    "14": "Rel;1",
    "16": "LED_n;1"
    }

    Thanks! It's interesting to see next WinnerMicro device. That's very informative, however, I can see a typo here:

    TYWE3S is not the same footprint as other modules listed. I think you meant TYWE2S.

    yes, fixed ;)

    i have bought additional 4pcs of this switch today for 1.4eur/each, it's interesting to connect some sensors (i2c light, temp etc) to free gpio ports.

    as far as i understand, you recommend to use PowerSave command on cheap Chinese power modules. will it affect on external sensors?

    The best way is just to try. Compare results. I dont think it may affect external sensor, but I am not sure.

    DHT11 and similiar sensors can be easily connected to unused GPIOs

    Is there any list of supported sensors? I have not found it.

    Well, here is a drivers list, but not all of them are enabled by default on W600:
