C1 - Public
All NINA-B4 standalone modules include an Arm
®
Cortex
®
-M4F microcontroller with a 64 MHz system
clock, 512kB internal flash and 128 kB RAM.
EVK-NINA-B4 evaluation boards provide access to the 38 GPIO pins and interfaces that are supported
on NINA-B4 modules. The interfaces are available through a variety of connectors, including Arduino™
Uno R3 [1] and Raspberry Pi [2] header connectors. The boards alos 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.
Nordic Semiconductors, the manufacturer of the nRF52833 SoC, provide a free Software
Development Kit (SDK) that includes a broad selection of drivers, libraries, and example applications
that can be used for rapid prototyping.
