Ordered a Raspberry pi 3 b+ today from eBay. Only getting the board, a 16gb micro SD card, and two heat sinks with it. No power supply. Recommended power is 5v 2.5a for efficient peripheral usage of the USB ports. I have several adapters but they are all 1.5 and 2 and 3v. No 2.5v. reluctant to use the 3v but plan to use a WiFi adapter with an Atheros 9271 chipset which gets pretty warm when used with my laptop. So will 2v be enough juice for the Atheros chip when I plug it in the pi?

nigga you need 5V
a smaller one will probably fine
heatsinks are a meme imho just like cases
William Morales
OP, do this, but be careful. Might need to underclock the Pi first. Also shit is gonna be unreliable.
Aaron Martinez
That doesn't mean that.
Seems like you never used a Pi in your entire life.

i'm assuming you meant to write 'a' instead of 'v' in all of this
a 3A supply is perfectly safe, you can never have too many amps in a power supply, if the device only draws 2.5A, it will draw 2.5A regardless of if the supply is 2.5A, 3.0A, or 200A
Aiden Flores
Use the official power adapter.
Daniel Watson
I think op meant amps(a) instead of volts(v) when referring to 1.5, 2, and 3. A 5 volt 3 amp adapter might be too much power for the pi where as 2 amps might not be enough to power the pi and Atheros WiFi adapter efficiently. Op better be on the safe side and get a 5v 2.5a adapter.
Christopher Myers
not him, but i've had a 1B for ages now and i've never seen this error, despite running it from all kinds of power sources (some inadequate)
Logan Cook
>A 5 volt 3 amp adapter might be too much power for the pi
no, it's 5V and at least 2.5A, which means it's perfectly enough power for the pi
you can't have too many amps
just look at usb adapter for cars, you think they can take 200A+? (a car battery will happily melt the tiny wires in those if you gave it a chance) no way, amps are "drawn" by a circuit, based on how much resistance it has
more amps than designed for can only damage a circuit which is already faulty (such as short-circuited)
Adrian Nelson
Pi 3B+ can draw up to ~1.5A by itself if you stress the CPU while simultaneously transmitting over Wi-Fi; so if you don't plug in any USB devices or add-ons that require additional power, you can use a 2A adapter.
Why do you want to use an external Wi-Fi adapter when Pi has one built in?
Isaiah Jones
>you can't have too many amps
You can have too many amps if it's a constant-current supply rather than constant-voltage. But those are almost never found outside of LED lighting applications, and certainly don't exist in the form of wall adapters with microUSB plugs.
Jason Sanders
1.5 and 2 will work depending on what you connect to it, i'm using a 2a adapter just fine
Ethan Evans
there are always exceptions to the rules, if someone is making an LED driver, they should already know about this
for the purpose of explaining common supplies, this is good enough
Joseph Lee
The power requirements for old and new Pis are very different. 1B is like 1.5W maximum and can be safely powered from a PC USB port, 2B is 2-3W, and 3B+ with wireless active can go up to 6-7W.
Leo Turner
Op here
Yeah I meant a instead of v. So I will probably use the 3a adapter with the pi. I've been cord cutting lately to save money. Gas prices are shit today. got rid of cable and got an ota (over the air) HDTV antenna for television viewing. Got rid of my internet service and got an old DirecTV dish and using it as a terrestrial antenna picking up WiFi from all over the neighborhood using a cantenna setup. Tried using my laptop (HP Stream model), Kali Linux, and an Atheros 9271 chipset WiFi adapter to hack a few BSSIDs. No luck. Laptop must be inferior...IDK...so I'm gonna try a pi.
Ryder Moore
u wot m8
if your wireless adapter cannot pick up the signal when connected to a PC, what makes you think that it'll work better with a pi?
William Wood
Kali Linux on my HP Stream laptop will pick up most, if not all, of my neighbors WiFi signals bssids when I use airmon-ng, aireplay-ng, aircrack-ng, etc. The problem is the handshake authentication into the router(s). I don't think my cheap HP Stream laptop can hack it
Charles Flores
If you think a Pi is more powerful than whatever Celeron is in your HP, or if cracking Wi-Fi has anything to do with how cheap your laptop is, you're a dumbass. I hope you end up stealing wireless from a bait AP set up by another dumb script kiddie who sniffs your passwords.
Dominic Lewis
Just get a 5.25v 2.5a supply so it never undervolts. Adafruit has them for the Rpi:
adafruit.com
>This adapter was specifically designed to provide 5.25V not 5V, but we still call it a 5V USB adapter. We did this on purpose to solve a problem that occurs often with USB-powered gadgets: they draw so much current that the resistance of the cable causes a voltage drop, so instead of 5V, the device sees 4.75V or so. To avoid this problem, we made the adapter 5.25V and the USB cable has extra-beefy 20AWG wires! This way, even at a full 2.5 Amp draw, the voltage at the end wont be lower than about 4.9V
Blake Cox
Power of your cpu shouldn’t have any effect on being able to capture a handshake. It certainly would when trying to crack the password though. Try the airgeddon script maybe you’re doing something wrong.
Justin Green
>2v enough
you need 5v with at least 2amps
Next youre gonna ask us what you can do with the raspi
Shove it up your ass.
Joshua Cruz
The pi does throttle under extended loads base, you can delay that slightly with the heatsink but for continual loads that don't hit throttle temp you need a small fan or a pretty large (relative to the pi's size) heatsink
Benjamin Murphy
You are retarded.
Aiden Jenkins
I run KDE Plasma for shits sometimes on my Pi and it heats that bitch up like crazy. Same if you’re running an OpenGL emulator for hours on end.
