+ | 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. | ||
