5. Powering the EVM:
• The EVM can be powered via USB connection or by external power supply:
a. Via USB power: Install shunt for JP1 if USB power is used.
b. External power supply: connect an external regulated power supply adjusted for 2.5 V–5.5 V to the
module VDD ( J8) and GND ( J7) banana jacks, taking care to observe marked polarity. Make sure
JP1 is removed in this case.
Note:
i. USB interface may not be able to provide enough current. For best audio performance, use
external power supply.
ii. Make sure only one power source is used. Connecting two power sources will cause damage
to the device and the supply.
6. Connect audio source to RCA jacks J4 and J3.
7. Connect speakers (8 Ω to 32 Ω ) to the output banana jacks ROUT and LOUT (J6, J9, J10 and J11).
8. Plug in USB.
9. Turn on the power supply.
