Q: Are these isolated?

Asked by tedhancock68 on 2020-07-10 02:22:24

Bricola No, this kind of module are not isolated, means the - (minus or gnd) line is common (you can see this on the back circuit picture). The + (positive) line pass through the IC MP2307DN, which is not optocoupled.

Bricola You may have a look by googling for (thanks to grumpy_gnome that gives this info in this forum). According to the specs of this datasheet, backlight current is about 180mA. By 4.2V means 0.756W. Hope this help.
