ESP32 custom board with ST7789

8 MB Flash / 8 MB PSRAM

ST7789 Display

ES8388 ADC-DAC / PAM8302




It looks very nice, how is the SD Card connected to the ESP32? If you’re using SPI, is the same SPI of the display controller?

I haven’t been able to share the same SPI of the display and the SD card connected via SPI.


This my schematic with some marked error
As you see I use SDIO
See reference design for more undestanding

I had some problem with running WiFi and BT
Also DAC ES8388 working not well. Noisy and low level of sound

Mee too. I tried one time SPI in parallel wit Display. I read than there is some problem with initialisation. Anyway I drop it
