Figure 1-1A for the GW48-CK-type EDA experimental development system board structure (GW48-GK/PK type does not draw, the specific structure of that kind should be taken into the motherboard), the experimental circuit of the system structure is controllable. Through the control interface can be key SW9, so that connection to change to adapt to the needs of different experiments. Thus, from the physical structure, the experimental board
