1. Overview

BL3353-P is an embedded Wi-Fi module designed by BroadLink, which supports

802.11 b/g/n standards and UART communication with other devices. The module
integrates radio transceiver, MAC, baseband, all Wi-Fi protocols, configurations and
network stack. It can be widely used in applications like smart home devices, remote
monitoring devices and medical care instruments.

The module integrates an ARM Cortex-M4 processor speed up to 125MHz and 256KB
SRAM with external 1MB flash.
