Application circuit diagram



Note the master chip IO port for all 3.3V voltage, when other microcontrollers connected to pay attention to voltage matching!

1. key control application circuit K1-K21 corresponds to 1-21 segment voice
2. MCU serial control application circuit

Above for the standard UART asynchronous serial port connection applications, this application is very flexible, including playback, pause, up and down, volume addition and subtraction, song selection, wide

and so on. Can be used single-chip, computer serial control, but also through the TTL to RS485 adapter board for 485 control
.
3. MCU IO port direct control application circuit

Through the microcontroller through the low pulse signal (equivalent to press the button to lift) can trigger IO1-I06, to achieve one-on-six playback of voice, and the above 3IO selectable control mode.
4. For some customers may use the level of the trigger play, you can use the rel
