Great product with some obvious ommissions
For Ardutex Trailing Edge I2C AC LED Light Dimmer
Probably possible to avoid that properly but it isn't worth the effort.
So the ommissions:
1. This has a full microcontroller on it so it seems weird to only use it as an I2C slave. Break out more pins! I am not using it as an I2C slave - I just used one of the two pins that are broken out to connect to a PIR sensor. I also had to remove the pullup but that's fine.
2. The microcontroller is not powered by the mains input, despite the board having a 12V PSU on it. So this means you need to supply another separate 5V PSU. It would be nice if the board just had a 12V-to-5V regulator on it.
Yes that would mean it isn't fully isolated, but in most cases this is surely just going in a sealed box somewhere so it doesn't matter.
Alternatively it could be optional - just provide 5V output pads on one side and 5V input on the other and I will connect them with a wire.
Overall, great product and there's no competition that I could find so buy this one. But with a few tiny changes it could be way better.
Oh also the designer wouldn't send me a schematic for some reason (not sure why, it's easy but time consuming to figure out), but they did at least reply which is nice.
