-When implementing a certain input and output that requires GPIO, we found that the available GPIOs on the 40-pin connector are relatively few. The available GPIOs can be seen in the Docs link.https://docs.khadas.com/products/sbc/vim3/applications/gpio/40pin-header
+When implementing a certain input and output that requires GPIO, we found relatively few GPIOs available on the 40-pin or 16-pin connector. To this end, we removed the pins' original functions and enabled GPIO control. In this way, any pins that are not required can be fully utilized to expand more GPIOs.
-To achieve this, we have removed the original functionality of the pin and enabled GPIO control. This way, any pins you don't need can be fully utilized to expand more GPIOs.
