BoardPilotPC817 optocoupler module 2 channels con ESP32
Alimentazione 3.3-5 V
Bus GPIO
Pin e collegamento all’ESP32
| Pin | Ruolo | Pin ESP32 | Note |
|---|---|---|---|
| IN1 | Ingresso (lo pilota l’ESP32) | D25 | Pin order varies between boards: match by the printed label. Channel 1 input (LED side, series resistor on board) |
| IN2 | Ingresso (lo pilota l’ESP32) | D26 | Channel 2 input |
| G | Massa | GND | Input side ground |
| V1 | Non collegato all’ESP32 | — | Channel 1 output, isolated side |
| G1 | Non collegato all’ESP32 | — | Channel 1 output ground, isolated side |
| V2 | Non collegato all’ESP32 | — | Channel 2 output, isolated side |
| G2 | Non collegato all’ESP32 | — | Channel 2 output ground, isolated side |
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.
