u-blox EVK-ANNA-B112 Evaluation Kits

u-blox EVK-ANNA-B112 Evaluation Kits evaluate the ANNA-B112 module and design various low-power IoT applications using BLUETOOTH® 5, Bluetooth®mesh, and NFC. The EVK-ANNA-B112 evaluation boards provide access to all 25 IO pins and interfaces available on the ANNA-B112 modules through various connectors and interfaces. These interfaces include Arduino™ Uno R3 and Raspberry Pi header connectors. The ANNA-B112 module is based on the nRF52832 chip that uses an Arm® Cortex®-M4F microcontroller with 512kB internal flash and 64kB RAM. These boards 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. The EVK-ANNA-B112 evaluation kits operate at 5V to12V supply voltage range and -40°C to 85°C temperature range.
