Breakout Pins Detail
Display Control Pins:
| Pin No. | Symbol | Description |
|---|---|---|
| 5 | CS | Chip select pin for SPI interfacing |
| 7 | CLK | Clock pin for SPI interfacing |
| 9 | D/C | Data/Command pin, Logic HIGH for Data and Logic LOW for Command |
| 11 | DIN | MOSI pin for SPI interfacing |
| 13 | RST | Reset pin |
| 15 | BL | BackLight for Display panel |
Touch Control Pins:
| Pin no. | Symbol | Description |
|---|---|---|
| 1 | SCL | Serial Clock pin for I2C interfacing |
| 3 | SDA | Serial Data pin for I2C interfacing |
| 18 | IRQ | Touch Controller Interrupt pin, Logic LOW when touch detected |
| 20 | TRS | Touch Controller Reset |
Note: RST & TRS pins connected internally so while interfacing with MCU's GPIO you can use only one instead of both
Power Pins:
| Pin no. | Symbol | Description |
|---|---|---|
| 17 | GND | Common Supply Ground pin |
| 19 | 5V | 5V Input Supply |
| 21 | VCC | High Side Supply for Level Shifter, Not required when using with 3.3V/5V MCU |
| 22 | 3V3 | 3.3V Input Supply |
Note: Using only one supply 5V or 3.3V at a time is enough to power Display Module
