VOL KW41Z

Overview

The VOL KW41Z module is an ultra-compact, low power, high sensitivity module that supports Zigbee®, Thread with IEEE 802.15.4 and Bluetooth Low Energy (BLE 4.2) RF connectivity. Built with a 32-bit ARM® Cortex® M0+ CPU operating up to 48 MHz, and an integrated chip antenna, VOL KW41Z provides OEMs with a dual RF solution for dynamic application needs, with minimal development, reduced risk, and faster time-to-market. VOL KW41Z is enriched with mikroBUS compatibility to connect to third-party products with a single click. It is an ideal solution for true single-chip designs that require concurrent communication on Zigbee®, Bluetooth Low Energy 4.2 and 802.15.4 based networks such as Thread, at reduced BOM cost. This multi-mode functionality as Thread module and Bluetooth module allows direct integration into thread mesh networks and direct communication with mobile devices via BLE.
