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 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 preflashed 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.
