XW71-WiFi
1. Product overview
The XW71N WiFi module is a complete BLE5.1+ WiFi network solution that can
operate independently or as a slave to other host MCUs. The module can be booted
directly from the built-in Flash when equipped with external applications and acting
as the only application processor in the device; it also contains a low-power ARM-
CM4 MCU, 1T1R WLAN, up to 120MHz, built-in 256K SRAM, 2Mbyte flash and rich
peripheral resources.
The XW71N WiFi module supports the IEEE 802.11 b/g/n protocol standard,
BLE5.1, supports lightweight TCP/IP protocol stacks, and supports STA, AP,
AP+STA modes. Users can use the module to add networking capabilities to existing
devices or build stand-alone network controllers.
Provide customers with complete hardware and software reference programs
to shorten your product development cycle and save costs for you.
