More details about V13 Headers
- The difference between V12 and V13 is determined by PIN#13/14/15/16 on 26-pin Header 2.
- 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.
- When I2C3 is used, you should only select one of the two groups, PIN#11/13 on 26-pin Header 1 and PIN#13/14 on 26-pin Header 2.
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
Power supply
1.The pins, PIN#2 and PIN#4, can supply power of 5V. The maximum current that can output depends on the power adapter.
2.The pins, PIN#1 and PIN#17, can supply power of 3.3V. The maximum current that can output is 200mA.
