General Description 

This document is to specify the product requirements for 802.11a/b/g/n Dual-band module and Bluetooth Low Energy (V5.0). This module based on Realtek RTL8720DM-VA1 chipset that complied with IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11a standard from 2.4~2.5GHz and 5.15GHz ~ 5.85GHz, and it can be used to provide up to 11Mbps for IEEE 802.11b, 54Mbps for IEEE 802.11g, 150Mbps for 802.11n to connect your wireless LAN. RTL8720DM-VA1 is a highly integrated single -chip low power dual bands (2.4GHz and 5GHz) Wireless LAN(WLAN) and Bluetooth low Energy (V5.0) communication controller. It consists of a high-performance MCU named KM4, a low power MCU named KM0, WLAN (802.11 a/b/g/n) MAC, an 1T1R capable WLAN baseband, RF, Bluetooth, and peripherals. High speed connectivity interfaces, SDIO and USB are provided. There are also audio codec, Key-Scan and touch keys integrated into this IC. Besides, flexible design configures GPIO to different functions according to applications.
