Features:1. Simple operation: This product is easy to operate. First, set your desired delay by adjusting the on-board trim pot: nearly-all-the-way-to-the-left is "once per 100ms" and all-the-way-to-the-right is "once every 2 hours". Then, connect VDD up to your 3-5V power supply and then your project's power-in to the Drive pin. Finally, select a signal pin from your project to the Done pin. In your project's code or design, just Make sure that it sets the Done pin high once it is completed with its task.2. Wide application: This product can be widely used in various electronic products and turned into low-power electronic products, which is very environmentally friendly.3. Timing function: This product has built-in timer, which can turn on or off your product regularly by adjusting the potentiometer or resistor.4. Complete assembly: This product is a fully assembled distribution board with TPL5110 chip, all components on board and some connectors. A little bit of light soldering is needed to put it together for the breadboard.5. Low power consumption: The current consumption of this product is about 20uA during operation, which can effectively save electricity and cost-effective.Descriptions:1. The TPL5110 Power Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of turning your project on/off using a built in timer that can vary from once every 100ms up to once every Two hours.2. Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power.Specifications:Color: BlueCurrent consumption: 20uAChip: TPL5110Package Included:1 x Low Power Timer Breakout
