LSC Smart connect Smart LED MOOD LIGHT 970743 teardown

maarten682  Cool? (+10)

This is an egg shaped 10 euro R-G-B-CC-CW 'moodlight' that can be found in Action stores in te Netherlands. There is no power supply included, it requires a USB power supply to function.

The device consists of a top and a bottom shell, the main pcb with pushbutton and usb-c connector is screwed into the bottom half and the board with 3 phillips screws and the board with the LEDs is snapped with plastic clips in the top half. Nothing is glued, its all just snapped together.

Opening the device up is fairly straightforward just squeeze it hard right on the seam where the two halves meet. A wood clamp will make short work of this. Both PCBs are far enough away from the center of the device that squeezing it hard will not damage anything and the housing is sturdy enough to jump right back into shape even after opening it multiple times.



As you can see in the second picture there's little notches that you have to line up when you are snapping it back together.

Thank you very much for that description. I've done this mod, but in my case it was enough to solder 3 wires (rx, tx, gnd). I used this soft: BK7231GUIFlashTool - https://github.com/openshwprojects/BK7231GUIFlashTool... [Read more]

Thanks for the great description! I managed to reflash this module by plugging in only RX, TX and GND - everything went right away, using: BK7231 GUI Flash Tool - https://github.com/openshwprojects/BK7231GUIFlashTool... [Read more]

Just please remember, do not power device from mains when flashing , many power supplies do not provide isolation from mains and there may be live potential on even the ground lane! It's better to power... [Read more]

Yes - of course - but to be honest it wasn't connected to anything else than those 3 wires, visible on photo. I've flashed 3 units that way - don't know if it's a magic or just a science :) [Read more]
