NINA-W1 series - User Manual
1.7 W1x6 integrated antennas
To simplify integration, W1x6 modules are equipped with an integrated antenna. An integrated
antenna design means there is no need for an RF trace design on the host PCB. This means less
effort is required in the test lab.
The NINA-W1x6 modules are equipped with a PCB trace antenna that is based on technology
licensed from Proant AB.
1.8 Reserved pins (RSVD)
Do not connect the reserved (RSVD) pin. Reserved pins are allocated for future interfaces and
functionality.
1.9 GND pins
Good electrical connection of module GND pins, using solid ground layer of the host application
board, is required for correct RF performance. Firm connections provide a thermal heat sink for the
module and significantly reduce EMC issues.
