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.
1.2.3
Software options
NINA-B1 can be used either together with the pre-flashed u-connectXpress software, or as an Open
CPU module with which you can run your own applications developed with either Arm® Mbed™, Nordic
SDK, or embedded Wirepas Mesh development environment in NINA-B1. See also section 2.
u-connectXpress comes with separate mesh software and is available for download from the

Pin configuration and function
See the NINA-B1 series data sheet [2] for information about pin configuration and function.

Supply interfaces
1.4.1
Main supply input
The NINA-B1 series uses an integrated DC/DC converter to transform the supply voltage presented
at the
VCC
pin into a stable system core voltage. Due to this, the NINA-B1 modules are compatible for
use in battery powered designs.
