BoardPilotSIM800L GSM/GPRS module (2G) con ESP32
Alimentazione 3.4-4.4 V
Bus GPIO
Pin e collegamento all’ESP32
| Pin | Ruolo | Pin ESP32 | Note |
|---|---|---|---|
| NET | Non collegato all’ESP32 | — | Antenna connection |
| VCC | Alimentazione | 3V3 | 3.4 to 4.4 V with peaks up to 2 A. Use a Li-ion cell or a buck converter, not the ESP32 pins |
| RST | Ingresso (lo pilota l’ESP32) | D25 | Reset, active LOW |
| RXD | Ingresso (lo pilota l’ESP32) | D26 | UART: the module receives here (2.8 V logic). Connect to an ESP32 TX pin through a divider |
| TXD | Uscita (la pilota il componente) | D27 | UART: the part sends data here. Connect to an ESP32 RX pin. Auto-baud: try 9600 or 115200 |
| GND | Massa | GND | Connect to ESP32 GND too |
| RING | Uscita (la pilota il componente) | D32 | LOW on an incoming call or SMS, optional |
| DTR | Non collegato all’ESP32 | — | Sleep control, optional |
| MIC+ | Non collegato all’ESP32 | — | Microphone, optional |
| MIC- | Non collegato all’ESP32 | — | |
| SPK+ | Non collegato all’ESP32 | — | Speaker, optional |
| SPK- | Non collegato all’ESP32 | — |
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.
