Modul Timer Low Power Adafruit TPL5110

Descriere și specificații:

The timer will be activated periodically, adjustable by potentiometer or resistor, and will start your project. Then he will wait until a signal is received from the project to inform him that he can safely stop the power supply.

Use is easy. To begin with, you can set the desired delay with the potentiometer on the module. Rotating it all the way to the left you get 100ms, and turning maximum to the right you will get 2 hours. Next, connect the VDD to the 3-5V voltage source and power your project to the Drive pin. Finally, choose a signal pin from your project and connect it to the Done pin. In the code, make sure that the Done pin is set high when you need to stop the project feed.

While the module works but the rest of the project is off, it consumes about 20uA.
