Connect it to your project's enable line, and the TPL5111 will handle the rest — setting the enable pin high at configurable intervals from every 100ms to once every 2 hours, then waiting for your project to signal when it's done.\n\nUnlike the TPL5110 which switches power directly, the TPL5111 controls an enable pin — making it ideal for boards that have a dedicated enable or shutdown pin. While your project is disabled, the TPL5111 draws only ~20µA, perfect 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\nEnable Pin Control – Drives an enable pin high/low rather than switching power directly\n\nUltra-Low Standby Current – ~20µA draw while the project is disabled\n\nDone Signal – Your project signals when it's finished so the enable pin can be deasserted\n\nWatchdog Behaviour – Automatically resets the device if no Done signal is received\n\nManual Override – Onboard tactile button to manually trigger enable (or wire your own switch)\n\n3V to 5V Input – Compatible with common battery and power supply voltages\n\n\nTPL5111 vs TPL5110\n\n\nTPL5111 (this board) – Controls an enable pin; best when your board has a dedicated enable or shutdown pin\n\nTPL5110 – Connects and disconnects power directly; best when you can break the power input line\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 Enable pin to your project's enable 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\nProjects with boards that have enable/shutdown pins\n\n\nPackage Contents\n\n1× Adafruit TPL5111 Low Power Timer Breakout (fully assembled)\n1× Header strip (requires soldering)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3017,"title":"Default Title","sku":"AF-3573","price":12.03,"on_sale":false,"in_stock":true,"available_quantity":73,"option1":"Default Title"}]}
