Includes encapsulated laser diodes that are Class IIIa 5mW, with a 650nm red wavelength. They can be driven from 2.8V to 5.2V so they're great for your embedded electronics project.
We're carrying this adapter primarily to allow Chumby Hacker Board users to adapt our nice 5V @ 2A power supply to their CHB. But you can use this adapter for anything else that has a 1.7mm DC jack, such as a PSP.
This incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 3.7W channels into 3 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC.
