Wemos D1 mini Pro how to move Zero Ohm Link to attach external antenna

You post some of the most helpful electronics videos on YouTube, promise me you're never gonna stop producing amazing content.

Thanks, I have been running an Outdoor WEATHER sensors, that I was struggling with a poor signal. After seeing this video, I now have a much better

Alex, thank you very much for the clear information. I just needed this information to connect an external antenna to the Wemos. I knew I had to interrupt something but didn't know exactly what to interrupt on the pcb. Joost

Instead of resoldering that tiny link, I'm much tempted to just bridge the gap with a glob of solder, like when connecting adjacent holes on a perfboard. Should work, but zero style points :-)

Excellent video. Thanks for taking the time to make it. FYI, a little flux will make this a whole lot easier.

You taught me how to do something I didn't even noticed I had to do. I can't thank you enough.

Thanks a lot man! You saved my "life" with that video... that little thing with almost 1mm :-/!!! i dropped it onto the grey garage floor - but luckily found it again --> and I soldered well --> before -74 and now -60 - works well!!!

I managed to de-solder and re-solder mine, wow that smd resistor is TINY!!!! I had to use precision tweezers, also filed my soldering tip to a fine point before attempting. Thanks for the upload.

This worked work great for me. To give a reference point, the signal dropped from high 70's dB to mid 40'dB(using antenna) They should have added a jumper! Thanks for the vid.

Thank you, for this gr8 video !
Would it make any sense do connect both the ceramic and the external antenna by just adding a blob of solder to the external connector ?

[MaxGoddur]

You video covers a question in need of an answer; how to use an external antenna?
Do see any improvement over the onboard PCB antenna? I have some boards that are just out of range of the wifi signal and would like to know if the range is increased and by how much with the external antenna.
Thank you for the great video.

Can you share the entire setup, like where you get the sketch from and upload it etc? I want to make something similar with a moisture sensor to measure soil moisture for my plants so that the system alerts me when I need to water them and put it around my garden.

Thanks for your video, I did desolder and resolder 0 ohm link as you show and it's working awesome! :-)

hi
what should be the upload rate for the D1 mini pro in the IDE software(115200?) and what should be the baud rate inside the code[Serial.begin(9600); ?] if a sensor has a baud rate of 9600?
like can there be 2 different rates at the same time and all works without frying anything?

[andreamitchell]

where can i buy it with the resistor already moved?
i see tons of links on aliexpress and ebay that sell it as a "kit" with the external antenna included but they all appear to have the resistor soldered for the ceramic antenna, makes no sense at all
all these Chinese sellers and nobody sells the kit with the resistor soldered for the external antenna even though they are selling it bundled with the antenna

[MrBobWareham]

Loved the video yes that was a small component but I think I will get one with the antenna
Do you have a link to the code please it looks very handy as I have a D1 and not sure if it is connecting to my WiFi as it stays on connecting!

[MrPlutoUSA]

Well done! Neurosurgery next? I'm not sure I could make my fingers do this one...

[RonenLin]

Do you know what type of ipex connector this board uses?

[ping]

Nice job and steady hand :)
Do you actually need to resolder the 0 ohm in place ? It seems these are some kind of workaround to allow use of pick and place machines, so a mere solder bridge should be alright.

I tried this today but something popped when I heated the link. Did anyone manage to get WI-PWN installed on the Wemos D1 Pro Mini?
