Kit Includes; Key Features - Ublox EVK-ANNA-B4 User Manual

All ANNA-B4 standalone modules include an Arm
clock, 512 kB internal flash and 128 kB RAM.
EVK-ANNA-B4 evaluation boards provide access to the 33 GPIO pins and interfaces supported on
ANNA-B4 modules. The interfaces are available through a variety of connectors, including Arduino™
Uno R3 [1] and Raspberry Pi [2] header connectors. The boards also support simple USB drag-and-
drop programming and 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.
