u-blox EVK-NINA-B4 Evaluation Kits

u-blox EVK-NINA-B4 Evaluation Kits are a versatile platform that allows prototyping of a variety of extremely low-powered IoT applications. The EVK-NINA-B4 features Bluetooth 5.1, NFC, and IEEE 802.15.4 and provides access to the 38 GPIO pins and interfaces that are supported on NINA-B4 modules. The EVK-NINA-B4 evaluation boards feature a dedicated USB connector for the NINA-B4 USB interface, simple USB drag-n-drop programming, and a SEGGER J-Link debug interface. These boards operate at 1.7V to 3.6 V supply voltage range.
