PWM Output on KC868-A8

[claudius]

I am using the KC868-A8.
I need at least ONE - preferably two PWM outputs from the KC868-A8.
Any idea except dismounting two(four) relays??

sorry, A8 no PWM output port.

sorry, A8 no PWM output port.

Any idea for a workaround?

sorry, no free GPIO with A8. unless you use a extend i2c pwm output module, you can search on aliexpress.

I found the
Pca9685pw 16 Kanal 12-Bit pwm Servo Shield Treiber i2c
at AliExpress.
Can you help with the I2C wiring on the KC868-A8 board and the software interface?
Thanks!

[admin]

you can use ESPHome config pca9685.
there is a white socket on A8 PCB, 4 pins printed label: SDA,SCL,GND,3.3V. just connect these wires to your new PCA9685 module is ok.

Thanks - I'll try.
