Here are the 5 datacrons you can find on Nar Shaddaa (Republic):
- Aim +3
- Presence +3
- Stamina +3
- Tip +3
- Yellow Matrix Crystal
Aim +3
The first datacron is in the Nikto Sector, go to (-3303; -3405) and climb on the containers in front of you, then pass on the canvas then on the rod to reach the high pipe. Take the pipes behind you to reach the floor, go opposite to see the datacron, after a little balancing act the datacron will be yours.
Presence +3
The second datacron is in the Red Light District, go to the "Gauntlet Territory" area (location of the quest H2 + Bloodthirsty Competition) then go to the place indicated on the minimap below, climb on the crate in front of you then on the canvas to reach the floor. Then take the elevator that will take you to the Red Light District footbridge, the datacron will be right in front of you just walk around to reach it.
Stamina +3
The third datacron may give you a bit of a hard time, go to the Shadow City in (2300; 3074) then climb on the crates in front of you to reach the floor, then go to the center to find new crates, climb on them to reach the small floating frame, then climb on the right pipe then on the light (sprint off if you want to succeed in jumping from the pipe to the light without worry). Then jump on the projector behind you (reactivate the sprint), then go on the pipes in the direction of the elevator, you will reach an access tunnel which will bring you to the datacron. (Preferably follow the screens ^^)
Tip +3
The next datacron is in the high security prison, go to (2039; 3387) and climb on the small crates in front of you to reach a footbridge, at the end of it is the incinerator room, enter -y. Here you will have to go through the flames to reach a terminal and enter a code (the code is 326: 3827), which will open the door behind which your datacron is hiding.
ATTENTION: Before leaving, take the "Machine decoder" in the slot machine which is next to the datacron, this one will be required for the datacron 5
Yellow Matrix Crystal
This is in the network security area, go to (1705; 3091) then climb on the containers in front of you as well as the pipes that go to the left to reach the floor where the slot machine is located. (Sprint off for the last two pipes). To unlock the slot machine's magnetic field you will need the "Machine decoder" collected along with the datacron 4.
