TiWi-SL

Self-contained 802.11 b/g WLAN module

Datasheet Product Brief

TiWi-SL is the industry's first industrial temp-rated 802.11 b/g Wi-Fi™ module. It has been designed for simple connectivity to the industry's most popular microcontroller platforms. It utilizes Texas Instruments' CC3000 SimpleLink™ technology to move nearly all the functions required for Wi-Fi™ off the host processor and onto the module.

Practical Applications

  • Smart energy, HVAC control
  • Home entertainment control, home monitoring
  • Medical
  • Sensor networks
  • Toys
