On a NanoPiNeoCore base:

Slot 1 GPIO Block Pin
Channel A 201 37
Channel B 200 38 
echo 200 > /sys/class/gpio/export
echo 201 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio200/direction
echo in > /sys/class/gpio/gpio201/direction

cat /sys/class/gpio/gpio201/value
cat /sys/class/gpio/gpio200/value

for Slot 2:

Slot 2 GPIO Block Pin
Channel A 3 37
Channel B 2 38 
echo 2 > /sys/class/gpio/export
echo 3 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio2/direction
echo in > /sys/class/gpio/gpio3/direction

cat /sys/class/gpio/gpio3/value
cat /sys/class/gpio/gpio2/value
