TLV493D 3D magnetic sensor con ESP32

Alimentazione 3.3-5 V Bus I2C Indirizzo I2C 0x5E / 0x1F Misura campo magnetico, posizione

Pin e collegamento all’ESP32

Pin	Ruolo	Pin ESP32	Note
VIN	Alimentazione	3V3
3VO	Non collegato all’ESP32	—	Output of the on-board 3.3 V regulator. Leave unconnected
GND	Massa	GND
SCL	Clock I2C (SCL)	D22
SDA	Dati I2C (SDA)	D21

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)

#include <Wire.h>

void setup() {
  Serial.begin(115200);
  Wire.begin(21, 22);  // SDA = GPIO 21, SCL = GPIO 22
  Wire.beginTransmission(0x5E);
  bool found = Wire.endTransmission() == 0;
  Serial.println(found ? "TLV493D 3D magnetic sensor found at 0x5E" : "Not found: check power, GND and SDA/SCL");
}

void loop() {}
