Arduino to Si4707 setup

Arduino    < ---------- >    Si4707 board
A4/SDA                           SDA    (via level shifter)
A5/SCL                           SCL    (via level shifter)
2(int 0)                            INTn   (direct connect)
4                                     RSTn  (direct connect)
3.3V                                VCC/VIO
GND                                GND/SEN


**SEN establishes the I2C address for the device. Placing a connection from GND to SEN allows the device to be used with provided Arduino library/sketch as written. If SEN is connected to 3.3V VCC then that will change the address and you will need to change the address of the device within the code to match that selection.

File schematic below is a from the user community for this device and incorporates an LM386 op amp for the audio. Thanks David!
