If state of SW1 is OFF, you can use this Pin Header. You can use the jumper cap to connect
the pin header to select the RXD / TXD pin for the Arduino.
⚫ JP1 – WizFi360 RXD (Connected to all pins of JP1)
⚫ JP2 – Arduino D0~D8 Pins
◼ Ex) JP2-1pin connected D0, JP2-2pin connected D1… JP2-9pin connected D8
⚫ JP3 – WizFi360 TXD (Connected to all pins of JP3)
EX) If you connect the jumper cap as shown in the Figure. 6, RXD is connected to D0,
TXD is connected to the D1.
