im trying to build a circuit board using a pwm input signal.
i found this simpel PWM controller relais and it has a no-name pwm ic controller to it.
i would like to know if maybe someone knows this .. has a datasheet or software that is necessary to use it.

this is a 5v pwm relais from aliexp...

greetings

Labeling simply unredable. This could be any chip...

pwm or controller or relay? Not both at the same time. You can't (at least not in a meaningful way) use a relay for pwm control.

Hello,

It can well be that the chip has been " mistified" to avoid copying.

its pwm relais for rc car or rc toy.
i have checked a bunch and they all have the same dimple in the corner. yet no number at all.
i have desoldered one just to see if it has a number on the bottom , yet no luck.
i thought mayb there is someone on this forum that knows what ic they use.

Possible ATTINY85 type.

Here is what it takes to program it to make a V to PWM control :

You config blocks and mBlock converts that to Arduino code (right window), you cut and paste into
Arduino and program board/chip.

2 of the cables, Red and Black, marked + and -, seem to indicate thats power
supplied to board.....
