Contents
[hide]General purpose input-output (GPIO) connector
ROCK Pi S has two 26-pin expansion header. Each pin is distinguished by color.
Hardware V10
26-pin Header 1
| GPIO number | Func4 | Func3 | Func2 | Func1 | Pin# | Pin# | Func1 | Func2 | Func3 | Func4 | [Expand] GPIO number |
|---|
Warning
- Pin#8 and Pin#10 cannot be used as GPIO, UART function pins since they are the data pins of SDMMC.
26-pin Header 2
| GPIO number | Func3 | Func2 | Func1 | Pin# | Pin# | Func1 | Func2 | Func3 | [Expand] GPIO number |
|---|
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
