RDA5802E FM FM Stereo Radio Module Development Board

RDA5802E FM FM Stereo Radio Module Development Board
Use RDA5802E chip research and development from a new generation of digital FM radio module, mainly used in MP3 / MP4 media player, has more prominent than traditional analogue radio module performance, excellent sound quality, minimal noise, lower power consumption, high integration of Actions, Rockchip, Ali and other popular programs are well compatible. This module can be directly compatible with products in the software part of the TEA5767, which in part can be a direct replacement for the module, do not need to change any part of the module in place and therefore can be directly replaced. RDA5802E can directly drive headphones 32 in Europe, you do not need an external amplifier performance than TEA5767 lot stronger.

The module supports voltage range 2.7-5.5VDC, using SMD components technology, through 3.5mm stereo headphone jack, direct drive headphones, the sound quality is excellent. This module can be used in conjunction with multimedia processing chip through I2C digital interface with a variety of SCM (51, AVR, PIC, MPS430, etc.). We will be able to learn a lot through this module interesting and practical knowledge, for example, can DIY your own intelligent CNC FM radio, you can achieve intelligent CNC clock radio with remote control function and so on ....
