When use this board, we connect it with the Infiduino Extension board using the 26P wire. Then plug this board on the breadboard, so D0-D13 and A0-A5 of Infiduino/Ardudino will be leaded to the breadboard. This way will make it easy for we to set up some proto circuit on the breadboard. The following steps will be convenient. Please note the following things.

  • There are two jumpers at each side of the Jtag connector, this is used to select the 3.3V or 5V voltage that is leaded to the breadboard.
  • When plug the Extension board on the breadboard, please don't use too much strength.
