Use a Directional Antenna with ESP8266-Based Board [Tutorial]

How to Fix a D1 Mini Pro for External Antenna Use

Cyber Weapons Lab, Episode 213

Directional antennas are a great way to put all of your Wi-Fi power in one direction, and they're useful for long distances or hunting down the source of a Wi-Fi signal. Unfortunately, using the antenna connector on the ESP8266 to add an antenna of our choice involves changing a resistor on the device. We'll show how to do this so you can add your own antenna to a D1 Mini Pro with an antenna connector!

I believe you could just bridge the gap after removing the resistor.

You don't actually need the SMD resistor. It's a 0 Ohm resistor, so a small wire (or just take cut of a small piece from a LED's pin) would work just as well, or just add some more solder to bridge the connectors, since it's such a small space between them.
I've done this on two of my ESP32-CAM's.

Awesome video! If you have some flux it will help to prevent it from flying away and make it easier to re-solder the resister back in to place, also it will make the solder joint much more secure.

Remimds me the USB meme 😂😂

I like the fact he said we should be able to use the board. I also prefer the word should. If it works you are the man. If it doesn't you are covered 💪

Just buy Iron Tweezers (aka Hot Tweezers) and make all this torture in one easy move. Hot air interventions are risky especially if you have cheap gun (with no thermal regulation).
In this case you can get the job done with simple soldering iron. 000 resistors practically are jumpers/bridges. It's more easier and safer to remove it and improvise a new one by merging the solder between the pads of the new direction instead of relocate the component.

Why couldn't you just use a blob of solder to bridge the two if they're that small?

This is awesome. I'm reinvigorated to get the yagi on this!

[el]

so say the 0 ohm gets blown away and is lost to the winds of time, can you use an enamel bodge wire instead?

[shiro]

would there be any other way if I happen to not own a heatgun?

[johnnymann]

Can you do a video on how to get kali nethunter on phone

[americannomadnews]

There's a cool video that makes me think of this setup that's called "building a camera that can see Wi-Fi"

[nursyamimi]

can i know the advantages when the directional antenna was being attached to esp8266?

[UnknownUser-pfrk]

Is there a way to do something similar with a normal ESP8266 without external port? Like soldering something to the leads that form the pcb antenna or something?

[GLocks]

since this is your latest video...can you do a video on open ports attack to access the web please

[u-ux]

wouldn't a solder bridge work (easier) instead of a 0 ohm resistor?

[brianwilliams]

Why not cut the track to the inbuilt antenna and simply bridge the open link?

[ItzShinePlayz]

The heat up applied A Small amount of heat but I can see A Bit of Proton occur while camera try to focus on the subject

[newstar]

Cut the trace to the board's antenna then add solder to bridge the pads to the external antenna.
