Product Description
RF-star low power consumption 2.4 GHz Wlan and 5 GHz dual-band wifi module CC3235
RF-WM-3235B1 is an RF module based on TI lower-power SoC CC3235SF with built-in dual-band Wi-Fi connectivity. It integrates a 40 MHz crystal, 32.768 kHz RTC clock, RF filters, diplexer, and two physical separated on-chip MCUs: Arm® Cortex®-M4 MCU with a user-dedicated 256 KB of RAM, an embedded 1 MB Flash and an external plug-in 4 MB Flash, network processor for running Wi-Fi and Internet logical layers. It features 802.11 a/b/g/n: 2.4 GHz and 5 GHz support, 2.4 GHz Coexistence with B radio, improved fast scan, hostless mode for offloading template packet transmissions and application features of small size, robust connection distance, and rigid reliability.
