Will it be willing to have a chat?
RX TX GND and VCC in form of V3.3Seems like they are made generic and some come with IR controller interface. One channel, but why are there Mosfets for 3 more channels on the PCB?
Do we have a 4channel RGBW card by just soldering 3 additional pins? Note the negative sign between the resistance and the N-mosfet.
Most LED strips works by controlling which channels are grounded and thus the electricity returns in the active negative channel.
Safety design as you don’t risk burning all Amps in the first LEDThose are a whole lot more expensive. Will be interesting to find out.
