Powering Arduino Uno Through different inputs

Adam_A
Adam_A over 2 years ago

Hello, recently I have been doing a project on an Arduino Uno that uses the display, however due to the limited space I have in my project build im unable to plug in power using the normal Usb option and 12v Barrel jack, the only way I could power it is I can wire power from a power supply to the Arduino Uno, I'm aware that I can use the inputs over here (on the power rail) to wire power to the Arduino (Refer to image 1)

However all of these inputs are occupied and it isn't possible for me to input power from there, so now we are left with the empty slots refer to image 2 (empty slots are highlighted in yellow)

My question is that are we able to wire 5V power from the Arduino power Supply (refer to image 3 for power supply) then to the Arduino Uno highlighted yellow slots??

    I'd go for these two solder holes (corrected after being reminded by @beacon_dave that VIN is before the regulator)

    imageOk, you now face the Arduino Dilemma!! You can't mount it, and it's not planed out well mechanically. I buy mine without pins or headers, then solder my own LONG-TAIL wire-wrap pin/header in place. Click on the image, please. This is how most of my Arduinos are mounted to my custom-made PCB base plate. On my base plate, I have male Wire-Wrap® pins and other goodies.
