power supply for Laser Diode - 5mW 650nm Red

Post by michael chang »

Hello all,

I read the description on the product (Laser Diode - 5mW 650nm Red, 25mA max current draw) page at https://www.adafruit.com/product/1054

It says that "You still need a 3 to 5VDC power supply."

Can it be powered by the 3.3V pin on Arduino Uno directly?!


Thanks

Yes. The 3.3v pin on the UNO can supply 25mA.
