Overview
The u-blox EVK-ANNA-B112 evaluation kit is a versatile development platform that allows quick
prototyping of a variety of extremely low-power Internet of Things (IoT) applications, using Bluetooth
5, Bluetooth mesh and NFC.
The u-blox EVK-ANNA-B112 boards are available in the following two variants depending on the
required antenna:
•
EVK-ANNA-B112U, with an ANNA-B112U module including u-blox connectivity software, and an
antenna connector for connecting to external antennas
•
EVK-ANNA-B112C, with an ANNA-B112C module including u-blox connectivity software and an
internal antenna (a unique 2.4 GHz antenna in the SIP).
The evaluation board provides access to all 25 IO pins and interfaces available on the
ANNA-B112 modules through a variety of connectors and interfaces, including Arduino™ Uno R3 and
Raspberry Pi header connectors.
The stand-alone ANNA-B112 is based on the Nordic Semiconductor nRF52832 chip. The nRF52832
uses an Arm
®
Cortex
®
-M4F microcontroller with 512 kB internal flash and 64 kB RAM, running at a
system clock of 64 MHz. The evaulation board provides 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
provides a free Software Development Kit (SDK) with a broad selection of drivers, libraries, and
example applications that can be used for rapid prototyping.
