Explanation of the 1.25 12P 11-channel IO and 1.0 6P 5-channel IO

The board defines 11 IO pins and GND; specifically, pins IO1–IO5 and VF0–VF4 are multiplexed together, meaning that the 1.0 6P 5-IO configuration and the 1.25 12P 11-IO configuration cannot be used simultaneously. When not in active operation, the 11 IO pins default to a high level (5V), while the 5 IO pins default to a high level (3.3V). When a control pin input is present, one IO pin is pulled to a low level, while all other IO pins remain at their high levels. The specific pin functions should be determined based on the external circuit connections and the corresponding program logic.
