BoardPilotCP2102 USB to UART adapter con ESP32
Alimentazione 3.3 V
Bus GPIO
Pin e collegamento all’ESP32
| Pin | Ruolo | Pin ESP32 | Note |
|---|---|---|---|
| DTR | Uscita (la pilota il componente) | D25 | Control line for auto-reset, optional |
| RXD | Ingresso (lo pilota l’ESP32) | D26 | The adapter receives here. Connect to an ESP32 TX pin |
| TXD | Uscita (la pilota il componente) | D27 | The adapter sends here. Connect to an ESP32 RX pin |
| 5V | Non collegato all’ESP32 | — | 5 V output from USB. Do not connect when the ESP32 is on USB too |
| GND | Massa | GND | |
| 3V3 | Non collegato all’ESP32 | — | 3.3 V output from the CP2102 regulator (about 100 mA max) |
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.
