u-blox NINA-B406 Evaluation Board

Added to your shopping cart

u-blox NINA-B4 Series Evaluation Boards are designed to evaluate NINA-B4 series modules. The evaluation kits include the NINA-B4 evaluation board, quick start guide, NFC antenna, and USB cable. These NINA-B4 evaluation boards are available in EVK-NINA-B400 and EVK-NINA-B406 variants that accommodate alternative antenna and software solutions. The EVK-NINA-B400 board comes with an open CPU NINA-B400 module and a U.FL antenna connector for connecting to external antennas. Whereas the EVK-NINA-B406 board comes with an open CPU NINA-B406 module that includes an internal PCB trace antenna.

The NINA-B4 evaluation boards allow quick prototyping of a variety of extremely low-powered Internet of Things (IoT) applications, using full Bluetooth 5.1, NFC, and IEEE 802.15.4. These evaluation boards provide access to the 38 GPIO pins and interfaces that are supported on NINA-B4 modules. The NINA-B4 boards support interfaces that are available through a variety of connectors, including Arduino™ Uno R3 and Raspberry Pi header connectors. These boards also provide simple USB drag-n-drop programming and a SEGGER J-Link debug interface that can be used with the open CPU variants of the EVK.
