3.4.4 When using ESP32-WROVER-B module + ES8311 to design audio development
board, which pins can be selected for MCLK clock?
• On the hardware side, MCLK can only use GPIO0, GPIO1, and GPIO3 pins. Other pins cannot be used. You
can read ESP32 Datasheet
• Please refer to the schamatic of
• For allocation of pins, please refer to
3.4.5 Can ESP32-WROVER-E module use one I2S line to realize simultaneous broad-
casting and recording?
• Yes, you can refer to

3.4.6 Do Espressif modules support Spotify Connect?

:CHIP: ESP32 | ESP32-S2 | ESP32-S3 :
• Not supported yet. It is suggested to try dlna, which has similar functions.
3.4.7 When running the korvo_du1906 example on an ESP32-Korvo-DU1906 board, a
reboot caused the following error message: Guru Meditation Error: Core 0 panic'ed
(IllegalInstruction). Exception was unhandled. How to resolve such issue?
• Please check the power supply.
• it is recommended that the system be connected to an at least 5 V/2 A power adapter for sufficient current
supply.
