1 Product Overview LA-WE3L is a Low-Power Embedded Wi-Fi module. It is composed of a highly integrated radio frequency chip TR6260S1 and a small number of peripheral devices, with built-in Wi-Fi network protocol stack and rich library functions. LA-WE3L is embedded with low-power 32-bit microcontroller, 1Mbyte flash memory and rich peripheral resources. Users can develop embedded WiFi products to meet their own needs based on these. 1.1 Product Characteristics 2.4GHz，EEE802.
It is used in bulb lamp, ceiling lamp, wall switch, wall socket, adapter socket and other smart home products.
