JODY-W2

Host-based multiradio modules with Wi-Fi 5 and
Bluetooth 5.2

System integration manual

Abstract

This document describes the system integration of JODY-W2 series modules. These host-based
modules support Wi-Fi 802.11n/ac and Bluetooth

5.2 and are designed for both simultaneous and

independent operations. The JODY-W2 modules include an integrated MAC/baseband processor
and RF front-end components and are offered in both professional and automotive grades.
