1 Product description
Overview
The EVK-NINA-B1 evaluation kit includes an evaluation board, which can be used as a reference
design for the NINA-B1 series modules, a quick start guide, an NFC antenna, and a USB cable. For the
NINA-B111 module, the evaluation board has a U.FL coaxial connector for connecting to the external
antenna. The NINA-B112 module has an onboard antenna; thus the evaluation board does not have a
U.FL connector.
The main features of the EVK-NINA-B1 are:
• Available in two variants - NINA-B111 and NINA-B112
• All the NINA-B1 module pins are available at connectors
• Can be powered through USB, external power supply, or coin cell battery
• Has an onboard debug MCU that allows serial communication and flashing/debugging over USB.
The EVK-NINA-B1 evaluation kits are available in the following two different versions depending on
the NINA-B1 series module that is mounted:
• EVK-NINA-B111 – Evaluation kit for NINA-B111module with antenna pin
• EVK-NINA-B112 – Evaluation kit for NINA-B112 module with onboard antenna
This section describes the main connectors and settings that are required to get started. Figure 1
shows the EVK-NINA-B1 evaluation board.

⚠ Take care when handling the EVK-NINA-B112. Applying force to the NINA-B112 module might
damage the internal antenna.
