  1. RT9114B GUI User Manual • V3.0

  2. Quick setup guidelines How to operate the RT9114B GUI toolNote: You’ll need the Richtek Wrenboard I2C interface for controlling the RT9114B EVB. Install Richtek Bridgeboard utility. Then connect the Richtek Wrenboard board to the PC and connect the GND, SCL, SDA wires from Wrenboard to the RT9114B EVB. You can also connect the red 3.3V wire from Wrenboard board to the RT9114B 3.3V connection. Apply 8Ω speakers to the speaker connection and apply I2S digital audio signals to the J2 or J3 connector Apply 8~26V power to the EVB PVDD (do not hot-plug power, or add a 100uF/35V electrolytic capacitor to the EVB input). Then run the GUI tool, see GUI guide on the next pages
