Need wiring diagram for syn1301 stereo headset adapter
I would like to build a stereo headset adapter like the Mot SYN1301 for my motorcycle helmet. It would be helpful to have a schematic or wiring diagram of the SYN1301, otherwise I'll have butcher my own adapter. Does anyone have a schematic for the SYN1301? I am mainly interested in how the earphones, mic and switch are connected to the miniUSB.
If I mount the phones inside the helmet, and keep the volume at reasonable level it's no different than listening in your car. Thanks for your response. If you don't have a schematic for the circuit board, something showing what wire goes where would be helpful. I can give you an email address if needed.
I really don't want to recreate the circuit board. I actually don't know what the circuit does (does it amplify or is it just switches?), so I don't know if I need it. I can purchase a helmet headset that includes two speakers, a mic and a PTT switch. I need a diagram that I can use to wire up the helmet pieces to a mini USB plug. If the circuit board is necessary, I'll cut that out of my SYN1301 and wire that in too. Does that make sense?
