## Description

The Adafruit TPL5110 Low Power Timer Breakout turns any electronics project into a low-power system by periodically switching power on and off. 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. When 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. Key Features Adjustable Timer – Onboard trim pot sets the interval from 100ms to 2 hours Ultra-Low Standby Current – ~20µA draw while the project is powered off Done Signal – Your project signals when it's finished so power can be safely cut Watchdog Behaviour – Automatically resets the device if no Done signal is received Manual Override – Onboard tactile button to manually trigger power-on (or wire your own switch) 3V to 5V Input – Compatible with common battery and power supply voltages 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 Drive pin to your project's power 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 Extending battery life on any microcontroller project Package Contents 1× Adafruit TPL5110 Low Power Timer Breakout (fully assembled) 1× Header strip (requires soldering)
