yes, driver is right. But you can use KC868-A32, need to use KC868-AP or KC868-D16 dimmer controller work with driver.

I was trying to do the same as the video with A32, but I'm not sure if I can use the analog inputs. I get this error when configuring the yaml:
GPIO34 (34-39) does not support output pin mode.
Can this be done with this board? Which pin should I use?

which board model you are using?

KC868-A32 use these GPIOs for analog input:
#define ANALOG_A1 GPIO39
#define ANALOG_A2 GPIO34
#define ANALOG_A3 GPIO36
#define ANALOG_A4 GPIO35
maybe you have not select correct ESP32 model.

Here's my yaml config:
Code:
esphome:
name: "kc868-a32"
platform: ESP32
board: esp32dev
light:
- platform: fastled_clockless
chipset: WS2811
pin: 39
num_leds: 30
rgb_order: GRB
name: "light_strip"The error is at "pin: 39" => GPIO39 (34-39) does not support output pin mode.
But I guess the error makes sense, if these pins are for analog input, can they be used to send data?

these pins only use for INPUT, can't use for LED strip or any OUTPUT function.

Then I guess I can't control led strips this way with A32, no?

KC868-A32 have a serial port extend on PCB beside ESP32 module. if you don't need to use it. you can use these two pins for LED strip.
