Description
Description
NE555 Timer chip designed to create a few second delay to power up devices with the need to start a little bit later when power is applied.
Adjust delay time with the potentiometer.
USB 5V is integrated to the design as well. This USB power is also delayed.
Input voltage range: 10V - 14V
Fuse can be changed according to the rating of the devices connected to this power module.
