BoardPilotHC-12 433 MHz serial radio con ESP32
Alimentazione 3.3-5 V
Bus GPIO
Pin e collegamento all’ESP32
| Pin | Ruolo | Pin ESP32 | Note |
|---|---|---|---|
| VCC | Alimentazione | 3V3 | 3.2 to 5.5 V. Draws about 100 mA when sending at full power |
| GND | Massa | GND | |
| RXD | Ingresso (lo pilota l’ESP32) | D25 | UART: the part receives data here. Connect to an ESP32 TX pin (9600 baud by default) |
| TXD | Uscita (la pilota il componente) | D26 | UART: the part sends data here. Connect to an ESP32 RX pin |
| SET | Ingresso (lo pilota l’ESP32) | D27 | LOW = AT command mode. Leave HIGH (internal pull-up) for normal use |
| ANT | Non collegato all’ESP32 | — | Antenna: spring antenna or u.FL connector |
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.
