General purpose input-output (GPIO) connector

ROCK Pi E has one 40-pin expansion header. Each pin is distinguished by color. Before using the 40-pin connector (I mean you may use serial console cable or any HAT.), find where the PIN#1(PCBA silkscreen 1) is on ROCK Pi E.

IO Voltage

RK3328 have two IO voltages, 1.8V/3.3V. For ROCK Pi E, the voltage level of GPIOs showed in the tables above are 3.3V and tolerance of those are 3.6V.

GPIO number

Rockchip RK3328 GPIO has 4 banks, GPIO0 to GPIO3, 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 GPIO2_A2(PIN39 on 40PIN GPIO) as an example:

   GPIO2_A2 = 32*2 + 8*0 + 2 = 66

To set GPIO2_A2 output

   cd /sys/class/gpio
   echo 66 > export
   cd gpio66
   echo out > direction
   echo 1 > value     # output high
   echo 0 > value     # output low
