I've bought a mini 5V UPS board that I need to coninously power a Raspberry pi. In the image description I see that there are 2 D+ and 1 D- PINS INPUT (wall supply, for example), 2 D+ and 2 D- pins BATTERY, 2 D+ and 2 D- pins LOAD. Why there are more than one pin for each purpose? Do I need some Arduino cables to use this module? I've posted images here:

  • \$\begingroup\$ If those 2 pins are shorted together on the board, you don't need to use both (as long as the wires are not too thin or too long), you can just use 1 pin and 1 wire for those. They use 2 either to match connections on a specific board, or to reduce voltage drop and power loss of a single wire. \$\endgroup\$ – Edin Fifić Apr 7 '20 at 15:48
