* Pins marked with color orange are designed for default debug console.
* PWM: x2, PWM2/PWM3

== 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'''.

== 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
