i1421-sw Bluetooth &Wi-Fi module

Introduction

i1421-sw module is a small size and low profile of WIFI+BT combo module. It

provides SDIO interface for WIFI to connect with host processor and high speed UART

interface for BT. It also has a PCM interface for audio data transmission with direct

link to external audio codec via BT controller. The WIFI data rata can go up to

433.4Mbps in theory by using 1 stream 802.11a/b/g/n/ac MIMO technology and

Bluetooth can support BT2.1+EDR/BT3.0 and BT5.3.
