BoardPilotILI9488 3.5" TFT 320x480 with touch (SPI) con ESP32
Alimentazione 3.3-5 V
Bus SPI
Pin e collegamento all’ESP32
| Pin | Ruolo | Pin ESP32 | Note |
|---|---|---|---|
| VCC | Alimentazione | 3V3 | On-board 3.3 V regulator: 3V3 or 5 V both work on most boards |
| GND | Massa | GND | |
| CS | Chip select SPI | D5 | |
| RESET | Ingresso (lo pilota l’ESP32) | D25 | Reset |
| DC/RS | Ingresso (lo pilota l’ESP32) | D26 | Data / command select |
| SDI(MOSI) | SPI MOSI | D23 | |
| SCK | Clock SPI | D18 | |
| LED | Non collegato all’ESP32 | — | Backlight: to 3V3 (always on) or through a transistor for dimming |
| SDO(MISO) | SPI MISO | D19 | Leave unconnected if touch or SD misbehave: some ILI9488 boards never release this line |
| T_CLK | Clock SPI | D27 | Touch controller clock (XPT2046), shares the SPI bus |
| T_CS | Chip select SPI | D32 | Touch controller chip select |
| T_DIN | SPI MOSI | D33 | Touch controller data in |
| T_DO | SPI MISO | D4 | Touch controller data out |
| T_IRQ | Interrupt | D35 | LOW while the screen is touched |
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.
