TiWi-SL
Self-contained 802.11 b/g WLAN module
Status: End of Life
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
