1.1.1 Module architecture
Figure 1: Block diagram of NINA-B1 series
1.1.2 Hardware options
The NINA-B1 series modules use an identical hardware configuration except for the different PCB sizes and
antenna solutions. An on board 32.768 kHz low power crystal is always included and an integrated DC/DC
converter for higher efficiency under heavy load situations.
1.1.3 Software options
The NINA-B1 series module can be used either together with the pre-flashed u-blox connectivity software or as
an Open CPU module where you can run your own application developed with either Arm Mbed, Nordic SDK or
Wirepas development environment inside the NINA-B1 module. The different software options are described in
more detail in section 2.
