WBU042 PRODUCT SPECIFICATION June 13, 2019

This preliminary specification is subject to change without notice.

CHAPTER 1. MODULE OVERVIEW

The Foxconn WBU042 is a highly integrated module which features a low power 2x2 dual-band

Wi-Fi subsystem and a Bluetooth subsystem. The Wi-Fi subsystem contains the 802.11a/b/g/n/ac radio,

baseband, and MAC that are designed to meet both the low power and high throughput application.

WBU042 has a 32-bit RISC MCU that handles Wi-Fi and Bluetooth tasks, and an ARM Cortex-R4

MCU that could offload data frame processing in Wi-Fi host driver. The Bluetooth subsystem contains

the Bluetooth radio, baseband, link controller. It also uses the 32-bit RISC MCU for the Bluetooth

protocols
