SparkFun Nano Power Timer - TPL5110

Description

Sometimes we want to turn them off, but we want to turn them off. The SparkFun Nano Power Timer will run while consuming only minimal power (approximately 35nA) and turn your project on after the set amount of time. You can tell the Nano Power Timer to turn off the power when you are polling your sensors, posting data to the web, writing to your logger. No more running your microcontroller all day when you want to read the ambient temperature once per hour.

The TPL5110 delay is configured with the use of resistors. We've added a six-way DIP switch to select one of the five preinstalled resistors. The sixth switch is attached to a pad to add your own PTH (or SMD) resistor. The delays associated with the preinstalled headers are shown on the bottom of the board for quick setup. Additionally, you can select more than one switch to combine the resistors in parallel (up to 26 options not including the custom resistor), check out the hookup guide for a nice chart as to the total resistance and corresponding delay for each combination.

The Nano Power Timer can handle voltages between 1.8V and 5.5V as well as current up to 1.1A with times from 100ms to two hours You will find out how to turn your project on when you like.
