- Pins marked with color orange are designed for default debug console.
- PWM: x2, PWM2/PWM3
- SPI: x2, SPI1, SPI2
- I2C: x3, I2C0/I2C1/I2C3
- UART: x4, UART0/UART1/UART2/UART3
- ADC: x1, ADC_IN0. The max input voltage is 1.8V.
IO Voltage
RK3308 have two IO voltages, 1.8V/3.3V. For ROCK Pi S, the voltage level of GPIOs showed in the tables above are 3.3V and tolerance of those are 3.63V. For hardware V11 and V12, an ADC input is included (ADC_IN0). This ADC has an input voltage range of 0-1.8V.
GPIO number
Rockchip RK3308 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:
GPIO0_A0 ~ A7
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7
GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7
For Rockchip 4.4 kernel, the GPIO number can be calculated as below, take GPIO4_D3(PIN8 on 26PIN GPIO) as an example:
GPIO4_D3 = 32*4 + 8*3 + 3 = 155
To set GPIO4_D3 output
cd /sys/class/gpio
echo 155 > export
cd gpio155
echo out > direction
echo 1 > value # output high
echo 0 > value # output low
