<![CDATA[M5Stack Core 2 External WiFi antenna]]>Hello everyone,

Has anyone here tried installing an external WiFi antenna on the M5Stack Core 2? The built-in 3D antenna provides fairly limited performance, and I'm thinking about trying to mount an antenna with an SMA connector. My questions are:

Where on the PCB should I solder the wires for the SMA connector after removing the 3D antenna?
Where can I find the PCB schematic for the Core 2?
Any advice or experiences shared would be greatly appreciated!

Quite challenging to access to though. Maybe desolder the 3D antenna first.

Most things M5Stack are split between store. and docs., so see here for the schematic.

I was curious, so I had a look inside my Core2 and it looks like there might even be a convenient breakout port for the SMA connector behind the label.
