I want to use the external antenna, is it possible for me just plug an antenna, or I need to remove some components to disable the chip antenna?

Hi there,
A rework must be performed before the U.FL connector can be used; this involves swapping the position of a 3.3nH chip inductor. The modified board would appear as follows.

  • Here is for the external antenna:

  • And here is for the chip antenna:
    chip-ant
