But…WiFi capable ESP32s have a built-in antenna tho
Yeah i was thinking the same thing, but maybe the wifi router is far away so they needed to increase their range?
I have a ESP32-WROOM-32U which is a model that uses an external antenna
Ahhh, I knew there were some that took an external antenna but I always thought it was in addition to an internal one lol
Real question, not snark…why did you do this?
I don’t have a WiFi antenna, except the ones in my computers. Buying a WiFi antenna online would’ve taken 2-3 weeks, and I wanted to quickly test how it worked.
Was there no jumper on board to switch the external antenna to the built in one? Many boards just have a 0 ohm resistor that you can add or remove to change the antenna.
This model doesn’t have an onboard antenna afaik
Neat! My only criticism is that I find this a lot more than mildly interesting lol
I was about to say – you probably don’t want to connect the wifi antenna plugs of two cards into each other – that’d probably overdrive each other’s receiver and damage the cards or cause other issues, unless you had an attenuator in there somewhere. But it looks like you’re just using the antenna loop from the laptop into the esp32 …
Nice job! Z500?
It is
