    Powering a Sanwu 650nm 250mW laser

    Hi FireMyLaser, ok, I did not think about it like that, but you are right. I thought there are some basic circuits that are always valid but "just" have to be parametrized a bit. I'll give it a go: - I understand, that MOSFETs do limit the current. They do not set the current to a constant...

    Powering a Sanwu 650nm 250mW laser

    Hello everyone, I just bought some more or less noname 250mW 650nm laser diodes (de.aliexpress.com/item/4000826011161.html). I removed the heatsink and at the back of the driver I can see the "SANWU" tag. The circuit-board in the shop-images does not match the one I can see with the heatsink...
