PCM5102A I2S stereo DAC con ESP32

Alimentazione 3.3-5 V Bus GPIO

Pin e collegamento all’ESP32

Pin	Ruolo	Pin ESP32	Note
SCK	Massa	GND	System clock: connect to GND so the chip makes it from BCK
BCK	Clock SPI	D25	I2S bit clock, not SPI
DIN	Ingresso (lo pilota l’ESP32)	D26	I2S audio data from the ESP32
LCK	Chip select SPI	D27	I2S word select (LRCK), not SPI
GND	Massa	GND
VIN	Alimentazione	3V3	3.3 V or 5 V. XSMT (solder jumper on the back) must be HIGH or the output stays muted

Collegamento consigliato per l’ESP32 DevKit a 30 pin, evitando i pin della flash, di sola lettura e di strapping. BoardPilot lo controlla mentre colleghi.

Codice di partenza (Arduino)

void setup() { pinMode(26, OUTPUT); }  // DIN

void loop() {
  digitalWrite(26, HIGH);
  delay(500);
  digitalWrite(26, LOW);
  delay(500);
}
