This interface is ready to use. 1,2V en 3,3V are provided. Headers for RX/TX, I2S and GPIO outputs, GND and 5V are soldered on the pcb. The headers for the tuner are already soldered. There is an USB type B connector mounted on the pcb for suppling the 5V to the interface. You find also a line-out connector (jack 3.5mm) on the pcb. This print has no levelshifter onboard, so you can only use it with µcontrollers that uses 3,3V (NO UNO) for communication. A TOSLINK optical connector is NOT provided but connections for such connector are provided on the pcb.
