Baofeng UV9R (Waterproof) Programming with Arduino

    This is simple method to program UV9R Plus or similar waterproof radio's belonging to Baofeng family of radio's. Here we will be utilizing the USB to Serial interface of Arduino Uno to perform the required programming. Also we will be describing method to prepare radio interface adapter using easy to procure items like Common PCB , berg pins and jumper cables.

    UV9R Plus is IP57 dust and water proof resistant radio which requires special water proof interface cables to program the channels and update radio related settings. Today we will go through the programming part of this radio. The inspiration to use Arduino to program the radio comes from here. We will be focusing more on building an interface adapter to avoid direct soldering in radio interface contact points.
