 The product pick of the week this week is the push button power switch breakout. This is an analog latching power switch that allows you to cut power or turn on power to your project at the push of a button. My favorite feature and one of the reasons I wanted to show this is this kill switch. It says there's a fourth kill pin which you can use to turn off the load or keep it off even if the button is pressed and this kill switch is a little secret sauce for having projects that need to be energy efficiency. You have a project with a battery, you want to be able to press it, have it do something and then have it turn itself off until the next time you come by. You don't have to screw around with any sort of low power watch dog timers and things like that. You can just have the thing after some task has been completed or after some amount of time the microcontroller can essentially cut its own power which is pretty cool.
