Especially\nwhen price and usability are the main selling points. So what should you do\nwhen it's time to turn around and make that project of yours run on a battery\nor solar? Sure you could try to hot air that regulator off, or you could Jerry\nRig A relay. Or, use a 555? Ugh, the options aren't that great.The Adafruit\nTPL5111 reset allows you timer is a stand-alone breakout that will turn any\nelectronics into low power electronics. It will take care of enabling and\ndisabling your electronics using a built in timer that can vary from once\nevery 100ms up to once every two hours. Basically, the TPL will set an enable\npin high periodically, adjustable by potentiometer or resistor, and turn on\nyour project's power. It will then wait until a signal is received from the\nproject to tell the TPL that it can safely disable the project by setting the\nenable pin Low.We also have a TPL5110 breakout, which rather than a setting to\nenable pin high\/low, connects and disconnects power. The TPL5111 breakout is\nbest when you have an enable pin you can control, the TPL5110 is best when you\nare able to 'break' the power input line to place the TPL5110 between the\npower supply and Vin.Usage is easy. First, set your desired Delay but\nadjusting the on-board trim pot: All the way to the left is once-per-100ms and\nall the way to the right is once every 2 hours. Then, connect VDD up to your 3\n5 V project power supply, and then your project's enable pin to the enable\npin. Finally, select a signal pin from your project to the done pin. In your\nproject's code or design, just make sure that it sets the pin high done once\nit is completed with its task. That's it.While the TPL5111 is running\/but the\nremainder of the project is the marriage of powered) the current draw is about\n20uA (according to our Monsoon Power Meters).If you want to turn the device on\nby hand, you can also activate the TPL by pressing the onboard T\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n  \u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":44374899622068,"sku":"de-B079G4G51V","price":133.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/de-B079G4G51V.jpg?v=1788267693","url":"https:\/\/auspowers.com\/products\/adafruit-tpl5111-low-power-timer-breakout","provider":"AusPower Australia","version":"1.0","type":"link"}
