BoardPilotESP-01 Wi-Fi module (ESP8266) con ESP32
Alimentazione 3.3 V
Bus GPIO
Pin e collegamento all’ESP32
| Pin | Ruolo | Pin ESP32 | Note |
|---|---|---|---|
| GND | Massa | GND | |
| GPIO2 | Non collegato all’ESP32 | — | Must be HIGH at boot. Leave unconnected |
| GPIO0 | Non collegato all’ESP32 | — | LOW at boot = flash mode. Leave HIGH for normal use |
| RXD | Ingresso (lo pilota l’ESP32) | D25 | UART: the part receives data here. Connect to an ESP32 TX pin |
| TXD | Uscita (la pilota il componente) | D26 | UART: the part sends data here. Connect to an ESP32 RX pin (AT firmware: 115200 baud) |
| CH_PD | Non collegato all’ESP32 | — | Enable: must be HIGH. Tie to 3.3 V |
| RST | Non collegato all’ESP32 | — | Reset, active LOW. Leave unconnected or tie HIGH |
| VCC | Alimentazione | 3V3 | 3.3 V only. Draws up to about 170 mA when sending |
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.
