Connect it between your power supply and your project, and the TPL5110 will handle the rest — powering up your circuit at configurable intervals from every 100ms to once every 2 hours.\n\nWhen the timer fires, the TPL5110 enables power to your project. Once your project completes its task, it signals the Done pin to tell the TPL5110 to cut power again. If no signal is received within the timeout period, the TPL5110 resets the device like a watchdog timer. While your project is powered off, the TPL5110 draws only ~20µA, making it ideal for battery and solar-powered applications.\n\nKey Features\n\n\nAdjustable Timer – Onboard trim pot sets the interval from 100ms to 2 hours\n\nUltra-Low Standby Current – ~20µA draw while the project is powered off\n\nDone Signal – Your project signals when it's finished so power can be safely cut\n\nWatchdog Behaviour – Automatically resets the device if no Done signal is received\n\nManual Override – Onboard tactile button to manually trigger power-on (or wire your own switch)\n\n3V to 5V Input – Compatible with common battery and power supply voltages\n\n\nHow It Works\n\nSet the timer interval using the onboard trim pot (or replace with a fixed resistor)\nConnect VDD to your 3–5V power supply\nConnect the Drive pin to your project's power input\nConnect a GPIO pin from your project to the Done pin\nIn your code, set the Done pin HIGH when your task is complete\n\n\nIdeal For\n\nBattery-powered sensor nodes and data loggers\nSolar-powered remote monitoring\nLow-power IoT devices that wake periodically\nExtending battery life on any microcontroller project\n\n\nPackage Contents\n\n1× Adafruit TPL5110 Low Power Timer Breakout (fully assembled)\n1× Header strip (requires soldering)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13287,"title":"Default Title","sku":"AF-3435","price":10.05,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
