JODY-W5 series
Host-based modules with Wi-Fi 6 and Bluetooth 5.3
System integration manual
Abstract
Targeted towards hardware and software application engineers, this document describes how to
integrate JODY-W5 modules in application products and explains the hardware design-in, software,
component handling, regulatory compliance, and production testing. It also lists the external
antennas approved for use with the module. Designed for a wide range of industrial applications, this
range of ultra-compact, cost-efficient, host-based, multiradio modules includes product variants
that are supplied with or without internal antenna. Integrated with a MAC/Baseband processor and
RF front end components, JODY-W5 modules connect to a host processor through SDIO for Wi-Fi,
and High-Speed UART for Bluetooth.
