## Description

The Adafruit TPL5111 Low Power Timer Breakout turns any electronics project into a low-power system by periodically toggling an enable pin. 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. Unlike 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. Key Features Adjustable Timer – Onboard trim pot sets the interval from 100ms to 2 hours Enable Pin Control – Drives an enable pin high/low rather than switching power directly Ultra-Low Standby Current – ~20µA draw while the project is disabled Done Signal – Your project signals when it's finished so the enable pin can be deasserted Watchdog Behaviour – Automatically resets the device if no Done signal is received Manual Override – Onboard tactile button to manually trigger enable (or wire your own switch) 3V to 5V Input – Compatible with common battery and power supply voltages TPL5111 vs TPL5110 TPL5111 (this board) – Controls an enable pin; best when your board has a dedicated enable or shutdown pin TPL5110 – Connects and disconnects power directly; best when you can break the power input line How It Works Set the timer interval using the onboard trim pot (or replace with a fixed resistor) Connect VDD to your 3–5V power supply Connect the Enable pin to your project's enable input Connect a GPIO pin from your project to the Done pin In your code, set the Done pin HIGH when your task is complete Ideal For Battery-powered sensor nodes and data loggers Solar-powered remote monitoring Low-power IoT devices that wake periodically Projects with boards that have enable/shutdown pins Package Contents 1× Adafruit TPL5111 Low Power Timer Breakout (fully assembled) 1× Header strip (requires soldering)
