GPIO Connector use 10 PIN 3.81mm Connector，It defined as P18 on the PCB board, As figure 8。
At the upside of the Connector，There are numbers from” 1” to “10”,it means the Pin number of the connector. As for the definition of every Pin, please refer to Table 4。
Attention: all the isolated GPIO use 5V Logic by default. If the customer provides external isolated power, the GPIO logic can be changed according to customer power (the “FB15” and “FB16” need to be removed on the PCB).
