The EVK‑NINA‑B5 evaluation kit serves as a complete starter kit that allows for easy prototyping and evaluation of the NINA-B5 series modules. The application software is developed with the chipset supplier's SDK NXP MCUXpresso, and programmed to the NINA-B5 module via the included onboard debugger. All the NINA-B5 module pins are available at connectors for easy access and measurements, and the board also includes multiple power supply options, buttons and LEDs.
The EVK-NINA-B5 evaluation kit includes an evaluation board with either the NINA-B506 module with integrated antenna, or the NINA-B501 module with an external antenna connected to the antenna pin via a U.Fl connector on the evaluation board.
