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!
