GET /P - change to previous station
GET /N - change to next station
GET /0..9 - select station
GET /0..9+URL - set station URL

Wiring is same as original, as ESP pin - I2S signal

----------------------
GPIO25/DAC1   - LRCK
GPIO26/DAC2   - BCLK
GPIO22        - DATA

and GPIO25/26 are fixed but GPIO22 can be re-arranged as you wish. (defined in components/audio_renderer.c)

I2C OLED is connected, as ESP pin - I2C signal

----------------------
GPIO14   - SCL
GPIO13   - SDA
