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! -

If you carefully look under the 3D antenna, you can see there are pre-soldered areas that look like for receiving an U.FL connector. Quite challenging to access to though. Maybe desolder the 3D antenna first.
