BoardPilotGY-87 10-DOF module (MPU6050 + compass + BMP180) con ESP32
Alimentazione 3.3-5 V
Bus I2C
Indirizzo I2C
0x68 / 0x77 / 0x1E / 0x0D
Misura accelerazione, rotazione, campo magnetico, pressione, temperatura
Pin e collegamento all’ESP32
| Pin | Ruolo | Pin ESP32 | Note |
|---|---|---|---|
| VCC_IN | Alimentazione | 3V3 | Goes through the on-board regulator |
| 3.3V | Non collegato all’ESP32 | — | Regulator output. Leave unconnected when you power VCC_IN |
| GND | Massa | GND | |
| SCL | Clock I2C (SCL) | D22 | |
| SDA | Dati I2C (SDA) | D21 | |
| FSYNC | Non collegato all’ESP32 | — | MPU6050 frame sync. Leave unconnected |
| INTA | Interrupt | D35 | MPU6050 interrupt, optional |
| DRDY | Interrupt | VP | Compass data ready, optional |
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(0x68);
bool found = Wire.endTransmission() == 0;
Serial.println(found ? "GY-87 10-DOF module (MPU6050 + compass + BMP180) found at 0x68" : "Not found: check power, GND and SDA/SCL");
