1. Product Overview 

WFM-210 Serial iAudio(Airplay/DLNA) module is a single chip wireless audio 

module that developed by Rayson Technology(Shenzhen) Ltd Company。 

WFM-210 Serial Wi-Fi Audio module integrates multiple audio formats such as MP3, 

WMA, RA, AAC, WAV, APE, FLAC and Hi-Fi lossless music decoding, maximum decoding 

capacity up to 4.5Mbps (24bit/192kHz),the biggest advantage in the ability for loss free 

streaming media transmission bandwidth and network。Also can support AIRPLAY 

protocol for APPLE device, support DLNA protocol for ANDROID device, support network 

media streaming protocol, remote control base on TCP/IP。 

 

WFM-210 Serial Wi-Fi Audio module can also be used for constructing the wireless 

network security monitoring, Intelligent wireless audio, wireless intelligent household 

appliances。 Support 802.11 b/g/n wireless standard, which can work in wireless AP/STA 

mode。For the main Wi-Fi standard 802.11g and 802.11n, the transmission rate is 

54Mbps for 802.11g, 150Mbps for 802.11n, all far more than the CD level quality required 

bandwidth。At the same time, WFM-210 can realize two device point to point direct, and 

also can through Wireless routing network.。 

 

 

For example, Android smart mobile phone connect to music box through  

WFM-210 can achieve shared music between multiple mobile phone, t the same time, 

can also satisfy the network multicasting, browsing demand, this is the Bluetooth cannot 

does。 

 

 

WFM-210 Serial Wi-Fi Audio module also support extended interfaces, such as 

Ethernet interface support cable internet access, USB interface can access USB extend 

storage device。 Support standard UART interface, and can be connected with MCU to 

achieve Wi-Fi wireless network control。 

 

1.1 Extended Application 

Wireless intelligent audio

 

Wireless intelligent portable speaker 

Wireless intelligent router and music player
