•
NFC antenna
•
USB cable
•
Quick Start card
1.3
Key features
•
u-blox NINA-B3 Bluetooth Low Energy module based on the Nordic nRF52840 chipset
o
Full Bluetooth 5 support
o
NFC tag functionality
o
802.15.4 PHY
o
Integrated Arm Cortex-M4 microcontroller with 1 MB flash, 256 kB RAM, and 64 MHz
system clock
o
USB 2.0
o
Wide 1.7-3.6 V supply range
•
The NINA-B3 module supports different interfaces that can be configured to any of the 38
available GPIO pin(s):
o
8 analog capable inputs
o
12 PWM capable outputs
o
3x SPI
o
2x UART with HW flow control
o
2x I2C
o
1x I2S
o
1x PDM input
o
1x Quadrature decoder
•
Full UART to USB converter with a Virtual COM port, allowing control of the extended UART
features of the u-blox connectivity software
•
On-board J-Link debugger/programmer
o
Mass Storage Device interface to PC, for drag-n-drop programming
o
Debug port
o
An additional Virtual COM port that, for example, may be connected to add-on boards
or to a debug UART on the NINA-B3
•
Dedicated USB connector for the NINA-B3 USB interface
•
Additional flash memory can be added to the board for use by the NINA-B3 module
