Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply voltage input; the operating supply voltage is specified as 1.8 V to 5.5 V. |
| 2 | PA4 | bidirectional | General-purpose bidirectional I/O pin PA4, also usable as ADC0 analog input AIN4, TCA0 waveform output WO4, or other alternate functions per the multiplexing table. |
| 3 | PA5 | bidirectional | General-purpose bidirectional I/O pin PA5, also usable as the VREFA external voltage reference input, ADC0 input AIN5, or TCA0 waveform output WO5. |
| 4 | PA6 | bidirectional | General-purpose bidirectional I/O pin PA6, also usable as ADC0 analog input AIN6 or the DAC0 analog output OUT. |
| 5 | PA7 | bidirectional | General-purpose bidirectional I/O pin PA7, also usable as ADC0 analog input AIN7 or the CCL LUT1-OUT output. |
| 6 | PB3 | passive | Port B pin PB3, shared with the TOSC1 32.768 kHz crystal oscillator connection and TCD0 output WO0 per the multiplexing table. |
| 7 | PB2 | passive | Port B pin PB2, shared with the TOSC2 32.768 kHz crystal oscillator connection and the EVOUT1 event output. |
| 8 | PB1 | bidirectional | General-purpose bidirectional I/O pin PB1, also usable as ADC0/PTC input AIN10, USART0 XCK, TWI0 SDA or TCA0 waveform output WO1. |
| 9 | PB0 | bidirectional | General-purpose bidirectional I/O pin PB0, also usable as ADC0/PTC input AIN11, USART0 XDIR, TWI0 SCL or TCA0 waveform output WO0. |
| 10 | PA0 | bidirectional | Pin PA0 is shared with RESET and UPDI; its function is selected by the RSTPINCFG fuse (GPIO, UPDI or RESET), and it also carries ADC0 input AIN0 and CCL LUT0-IN0. |
| 11 | PA1 | bidirectional | General-purpose bidirectional I/O pin PA1, also usable as ADC0 input AIN1, USART0 TxD, SPI0 MOSI, TWI0 SDA or CCL LUT0-IN1. |
| 12 | PA2 | bidirectional | General-purpose bidirectional I/O pin PA2, also usable as the EVOUT0 event output, ADC0 input AIN2, USART0 RxD, SPI0 MISO or TWI0 SCL. |
| 13 | PA3 | bidirectional | General-purpose bidirectional I/O pin PA3, also usable as the EXTCLK external clock input, ADC0 input AIN3, USART0 XCK, SPI0 SCK or TCA0 waveform output WO3. |
| 14 | GND | power_in | Ground reference for the device. |

Materials and finish
As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).
| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
| contacts | tin | including indium tin oxide (ITO) sensor grids. The PTC requires one pin per X-line and one pin per Y-line. In the Self Capacitance mode, the PTC requires only one pin (Y-line) for each touch sensor. | 461 |
