After figuring out which way to connect my voltage regulator. I realized how to wire the incoming voltage to the outgoing voltage, by using my multimeter. However, my breadboard adapter is only outputting 3.28V, for a 3.3V NRF24L01. Any suggestions?
3.28 and not 3.3.... That's within the specs for allmost every multimeter.
Be happy and go on!

I know right, that's what I was thinking, but my nrf24l01 is not powering up.
Nrfl24 will work down to much lower voltages - check your wiring .
They don’t really do anything visual anyway ( no indicator leds ) so how do you know it’s not powered .
Run software example… and of course you need two to communicate !
Robin2's simple rf24 tutorial has an example code called CheckConnection.ino (look in reply #30 in the tutorial) to verify the physical wiring between the radio module and its attached processor (Arduino).
The led isn't coming on.
I haven't attached the Nano yet, because the power isn't coming on, for the nrf24l01. The breadboard adapter side I'm using, indicates ground (square silkscreen), in the left and right corners.
post an image of your project on the breadboard, please.
Okay.
post the link where you got the narfie from.
if the narfie thing is the thing with the cable then the power to the connector thingy is on the wrong side. Also V+ goes to the left and gnd to the right.
Match the narfie connections to the pin out illustration on the narfie.
What's the narfie? If your talking about the voltage regulator it was Amazon, the breadboard adapter is by Maker Focus. It too is off of Amazon. I've been on their site, and I cannot find the datasheet.
Yeah, I was confused on the illustration corresponding to the nrf24l01.
Did putting the wires in the correct location get the narfie to light up?
Post an image of the revised connections.
Naw man, my by board started popping and fizzling the moment it touched it. I'm going to switch the adapter around.
Now the multimeter is reading a little over 10V each time.
something fried.
Yeah. I'll have to put this other one together now, but hey, my narfie still powers on 
. I have a separate power modulator I use, to make sure the board is powering up. It just requires too much crimping, resulting in unreliable connections. Besides, The narfie is better secured in the breadboard, or pcb .
So I'm thinking I need to flip the breadboard adapter around. I was looking at some customer pictures, and the side with the BB-ADTR inscription is the front side. This is the side where the 8 pin header is soldered to. However, this criss crosses the ground and power pinouts. I figured it's criss crossed because the ground is usually indicated with a square. The ground for the nrf24l01 is on the other side though.
Well that didn't work either. I think it's because of the voltage regulator not being flushed against the pins enough. I soldered a second one, I guess I'll do another.
So I soldered a third voltage regulator, and voila, I finally got 3.3 V. Maybe also because I resoldered the breadboard adapter. Despite this, my nrf24l01 is still not powering on. I guess I can try powering the power bus with 3.3v, and connecting the breadboard adapter to that.
