We're handling some wireless LEDs - pretty amazing stuff. Again we're sponsored by PCBWay.com/?from=atomic
I saw these LEDs on the Tested channel originally (youtube.com/watch?v=QL7bwm_FqlA) and decided that I had to have some.
You can buy them here from Aliexpress (affiliate link): https://s.click.aliexpress.com/e/_A4gUEH
If you want to make your own LEDs then a 2.2mH inductor and 220pF capacitor seem to work well - you can see how to do it here: youtube.com/watch?v=jdc_0r5pJPc
The mystery chip has been identified - it's a XKT-001 and it's actually controlling XKT-333.
आदित्य Aditya मेहेंदळे Mehendale points out:
The XKT333 looks suspiciously like a MOSFET. I suspect that the 6/7 pin chip is/are the "brains" and the XKT333's gate (pin 8) is driven by pin2 of this other chip with a square-wave. The duty cycle of the square wave is likely 44% - hence "2.2VDC" (average) on this pin.
