| GPIO pins exposed on Raspberry Pi Pico headers. |
| |
| The Raspberry Pi Pico layout provides 2 columns of 20 pins headers |
| |
| This binding provides a nexus mapping for the default 26 pins as depicted below: |
| |
| 0 GPIO0/UART0_TX VBUS - |
| 1 GPIO1/UART0_RX VSYS - |
| - GND GND - |
| 2 GPIO2 3V3_EN - |
| 3 GPIO3 3V3_OUT - |
| 4 GPIO4/I2C0_SDA ADC_VREF - |
| 5 GPIO5/I2C0_SCL GPIO28/ADC2 28 |
| - GND GND - |
| 6 GPIO6 GPIO27/ADC1 27 |
| 7 GPIO7 GPIO26/ADC0 26 |
| 8 GPIO8 RUN - |
| 9 GPIO9 GPIO22 22 |
| - GND GND - |
| 10 GPIO10 GPIO21 21 |
| 11 GPIO11 GPIO20 20 |
| 12 GPIO12 GPIO19/SPI0_TX 19 |
| 13 GPIO13 GPIO18/SPI0_SCK 18 |
| - GND GND - |
| 14 GPIO14 GPIO17/SPI0_CSn 17 |
| 15 GPIO15 GPIO16/SPI0_RX 16 |
