Laser Scaler need 3.5 volts

(Luis Chavez) #1

Good day,

I am planning to install a laser scaler into my ROV2.

the laser scaler need 3.5 volts input, from where inside the electronics Can I get that voltage.



I might also install some lasers on our ROV… What are you using as a laser scaler ?

As for the voltage, I’d simply add an adjustable DC-DC converter. Just make sure that the current (Amps) needed by the laser sits in between the minimum and maximum current provided by the DC-DC.

There is no 3.5V that you can use. Check the power/current necessary and get a Buck (step-down) Converter. Either a 3.3V or an adjustable one.
Make sure that the input voltage supported can handle the battery voltage and that the output is adjustable or fixed at 3.3 V.

thanks for the hint, well received, I found some good step-down converter on ebay. I will continue with the project.

I have found the laser scaler with a chinese manufacturer. I would like to used before I recomended.
