1 Product Overview LA-WE2S is a Low-Power Embedded WiFi module. It is composed of a highly integrated radio frequency chip TR6260S1 and a small number of peripheral devices, with built-in WiFi network protocol stack and rich library functions. LA-WE2S 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 2.4GHzIEEE802.
It is used in such scenes as switching socket, wall switch, wall socket and circuit breaker, and supports voice control and Amazon cloud voice.
