Hi @CyberT:
The config table's naming of asus gpio input and output node are for Tinker Board S. And, the packages are development by third party member(https://github.com/tinycore-hisanori/node-red-contrib-tinkeros-gpio). But, i think it is compatible with Tinker Board 2 about gpio pin number.
You can replace the attachment file to /home/linaro/.node-red/node-moduels/red-contrib-tinkeros-gpio/nrgpio.sh file and asus output node would work by add sudo permission for Tinker Board 2.
Please help to try and verify it.
Thank a lot!
