JODY-W1 series

Host-based modules with Wi-Fi and dual-mode Bluetooth

System integration manual

Abstract

This integration manual describes JODY-W1 series modules with 2x2 MIMO 802.11n/ac and dual-
mode Bluetooth® 5. JODY-W1 is ideal for in-vehicle-infotainment and telematics applications with
simultaneous use cases requiring high data rates, such as in-car hotspots, Wi-Fi display applications
such as Apple CarPlay, or video streaming across multiple clients. Connection to a host processor is
through PCIe, SDIO, or high speed UART interfaces. It comes in an SMD form-factor, providing a
complete solution for easy integration into the application.
