      Q02. I need a base for the SOMO-14D Module?

      Ans.The spacing between pins is the standard 0.1" but the male headers have machined pins. So, you need a single Row base with machined pins. You can try some of the following links,

          Q04. In Serial Mode, does SOMO-14D need to be communicated Serially through the Com port?

          Ans. No, there is no UART type Rx/Tx or Serial Com port on the SOMO-14D Module. Serial mode here means, the data and clock are latched serially in to the Data and Clock pins of the module. You can use Digital IOs of your controller to generate the DATA and Clock signals to control the SOMO-14D in Serial mode.

              Q06. Do I need to send Play command to the SOMO-14D after i send the AUDIO FILE ADDRESS in the serial mode?

              Ans. No, The audio file starts playing as soon as you send the AUDIO FILE ADDRESS. You don't need to send PLAY command.

                Q07. When i send an AUDIO FILE ADDRESS to the SOMO-14D, does it finish the current file it's playing before playing the file requested?

                Ans. No, SOMO-14D immediately plays the file requested. It doesn't complete the file currently playing.

                  Q08. In the Key Mode, if i send PREVIOUS command, will it play the previous file or the current file?

                  Ans. Suppose file 0005.AD4 is playing and you sent PREVIOUS command, 0004.AD4 file would start playing.
