New teardown of Magic home WIFI RGB CTT controller

  • Hi,

    Like many perhaps I bought a Magic home controller expecting to flash Tasmota onto it and go from there...
    Turns out there is a different chip in side, and there you go down the rabbit hole. Thanks to someone with, I guess, a lot of perseverance and this beautiful community I could get this controller Magic home Wifi Led controller rgb + cct:

    with what turned out to be a BL602 chip inside to work.
    The insides, front and back are show below:

    The PCB identification read ZJ-BWCG-VC-RGBWW V1.1

    It took some tracing and measuring but I found the correct pinout for all channels and though I give something back to the community.
    The configuration I entered worked for me:
    P3 PWM Channel 2 / Green
    P4 PWM Channel 0 / Red
    P17 PWM Channel 3 / Cool white
    P20 PWM Channel 4 / Warm white
    P21 PWM Channel 1 / Blue

    Many thanks!

    Thank you for your presentation. It's good to mention that our OpenBL602 firmware supports now OTA - updating firmware via WiFi. It was not possible in the past but now you can just flash once by wires and then update many times wirelessly.

    Thank you!
    Yes I found the OTA option, and I was banking on it too, as the device is now boarded up and only accessible with a lot of effort. That was why I could not post a picture of the case after forgetting about it previously.

    Do you know if, and how, this template will be made available to others?

    I've also heard that BL602 is used in some of the Sonoff products. It's used in at least one kind of Sonoff bulb (which I will receive soon, thanks to one of our readers) and in one of Sonoff power-metering switches (with CSE chip, as far as I know)
