More details about 40-pin Header

  • Pins marked with color orange are designed for debug console.

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
