Tested I2C and V2 Variant

At first I got modules without I2C. That also worked, but here in the power grid the heart rate is often fluctuating. This made it difficult for me to write the right software. I managed this with a RaspberryPi Pico but with a Micropython code. It worked 99% of the time, but I couldn't adjust the fluctuations very well. This sometimes resulted in a slight flicker.

So I ordered the I2C variant and just tested it. This one works wurnderbar and you don't have to worry about all the timings. Very comfortable. As long as the I2C chip does not lose power, it even keeps the last setting, even with AC voltage drop. I like the product and the quality very much!

Great board

The quality if the boards is very high
Usage is explained very clearly online and also there are all needed connection markings on the board itself.
The board performs flawlessly and looks designed properly for the loads it has been rated for.

High quality board but flickers...need assistance.

So, the board appears to work however we wrote a small C++ program to ramp the lights up and down in increments of 1 at 60Hz (same and our power source in the US), thus taking a bit over 3 seconds per period. When driven that way the incandescent connected to it light flickers very noticeably. Since we were matching the power wave I expected it to be very smooth in terms of dimming. What are we doing wrong?

Works perfectly 😊👍

The dimmer works perfectly. All channels can be controlled as expected and regulate cleanly between 0-100%. Something unusual, but quite logical: 100% = light off; 0% = light on. I can absolutely recommend this dimmer. :)

Very good

The board works as described from manufacturer. One point only, some noise is produced by the light bulb when thr brightens is low. I will check with other light bulb manufacturers.
