I/O
Note: For this configuration, antenna connections may be made either via U.FL board-to-
board connectors as specified above OR via U.FL cables that go directly to the antenna.
The latter is preferable if the antenna is not part of the board assembly. These cables must
be connected BEFORE the module tabs are soldered to the board.

Ensure that the antenna line impedance is 50Ω
Keep the antenna line on the PCB as short as possible
Antenna line must have uniform characteristics, constant cross section, avoid meanders
and abrupt curves. Matching elements (L or C) can be added, but are not necessary for a
well designed layout.
Keep, if possible, one layer of the PCB used only for the ground plane
Place EM noisy devices as far as possible from the M6e-Micro
Keep the antenna line far away from the power supply lines, noisy devices such as fast
switching ICs. If a switching power supply is used, ensure that the switching frequency is
500kHz or higher.
