WF-R710-RTG1 SoC module designed base on RTL8710BN chip solution, The SOC module is a highly
intelligent platform for the Internet of Everything that contains a low-power Wi-Fi connectivity solution on
one package. It includes a number of TCP/IP based connectivity protocols along with SSL, enabling a
low-cost, low-complexity system to obtain full-featured internet connectivity and reliable information
exchange.

Realtek RTL8710BN is a highly integrated single-chip low power 802.11n Wireless LAN (WLAN)
network controller. It combines an ARM-CM4F 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 fordifferent applications and control usage.

RTL8710BN integrates internal memories for complete WIFI protocol functions. The embedded memory
configuration also provides simple application developments.

1.1 RF module Overview
