RW10BX-14P


 

1.Descriptions

The RW10BX-14P module is a highly integrated single-chip low power 802.11n Wireless LAN (WLAN) network controller. It combines an ARM-CM4 MCU, WLAN MAC, a 1T1R capable WLAN baseband, and RF in a single chip. It also provides a bunch of configurable GPIOs which are configured as digital peripherals for different applications and control usage.

The RW10BX-14P module also integrates internal memories for complete WIFI protocol functions. The embedded memory configuration provides simple application developments.
