1.3.1 NINA-B111
The NINA-B111 modules do not use the internal antenna and thus the PCB has been trimmed to allow for a
smaller module (10.0 x 10.6 mm). Instead of an internal antenna, the RF signal is available at a module pin for
routing to an external antenna or antenna connector.
1.3.2 NINA-B112
The NINA-B112 modules use an integrated antenna mounted on the PCB (10.0 x 14.0 mm). The RF signal pin is
not connected to any signal path.
