Mana SE with 1w Laser at 5v
Any suggesting to use this laser module with mana se?
I'm did burned one when i plug directly in 12v of board, after this i see the description of 5v
@ianobre It's just a diode in a lens holder, you need a constant current driver. A simple LM317 circuit would work, or you can get a dedicated driver.
This is way overkill for such a small diode but you get the idea:
@Zax a simple step down circuit can work too, right?
@ianobre Short answer: No. Use a current limiting circuit.
Diodes, whether LED's or laser diodes are low resistance so they need to be current limited. You could add a series resistor but as the diode heats up it's resistance drops so you get more current, and thus more heat, this lowers the resistance more... and you get what is called a waterfall or runaway until the diode fails. A single resistor will work but you won't get a stable or maximum output.
@Zax very clear, thanks.
Banggood is out of stock. This version can work Zax?
@ianobre I can't find that one to look at the specs, but it should be ok.
