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.
