1. Overview
BL3369T-P is a cost-effective 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 160MHz with 352KB SRAM
and 1MB flash.
