Encouraging your projects to use less power is always a good thing, and help has arrived in the form of the new TPL5110 Low Power Timer Breakout Board from Adafruit. Based on the Texas Instruments TPL5110, this neat board will take care of turning your project on/off using a built in timer that can vary from once every 100ms up to once every two hours.
Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power. Awesome!
