NAUTIZ X6 V2 Back docking connector

Pogo pin hardware define

Pins 6, 7, 13, 14 are turned OFF by default. These can be turned on via SDK.

1 GND Ground PIN 8 UART_RX 1.8V UART RXD
2 GND Ground PIN 9 UART_TX 1.8V UART TXD
3 GND Ground PIN 10 GPIO_1 1.8V GPIO 1
4 GND Ground PIN 11 GPIO_2 1.8V GPIO 2
5 GND Ground PIN 12 IRQ 1.8V External Interrupt PIN
6 POGO_5V 5V/1A DC-DC Power OUT (OFF default) 13 POGO_5V Same to PIN 6
7 POGO_VBAT VBAT Power OUT (OFF default) 14 POGO_VBAT Same to PIN 7

Pogo pin path define

The path can be obtained from the system properties. Each pin has a special attribute key, and the corresponding path can be obtained by calling the system attribute tool through reflection.

  1. POGO_5V
    System property key: ro.pogo.path.vbus
    Default value (if not define): /sys/class/ext_dev/function/ext_dev_5v_enable
  2. POGO_VBAT
    System property key: ro.pogo.path.vbat
    Default value (if not define): /sys/class/ext_dev/function/ext_dev_3v3_enable
  3. GPIO_1
    System property key: ro.pogo.path.gpio1
    Default value (if not define): /sys/class/ext_dev/function/pin10_en
  4. GPIO_2
    System property key: ro.pogo.path.gpio2
    Default value (if not define): /sys/class/ext_dev/function/pin11_en
  5. IRQ
    System property key: ro.pogo.path.irq
    Default value (if not define): /sys/class/ext_dev/function/irq_state
  6. Serial
    System property key: ro.pogo.path.serial
    Default value (if not define): /dev/ttyHSL1
