PURPOSE: A micro processor board with master/slave mode selection function is disclosed to provide a microprocessor board that can be selected in voluntary movement mode by attaching a microprocessor composed of a core with CPU's capabilities and communication control device that executes communication capabilities. CONSTITUTION: A micro processor board with master/slave mode selection function is composed of installation, connection, and switching. In order for the user to simplify the selection of a communication microprocessor's(110) movement mode, mode selection instruments(310), which are composed of switches(312,313,314) to select master and slave modes, are installed on the outside of the board. One side of a second switch(312), a first switch(310), and 0 switch(314) is grounded and the other side is connected to voltage levers through prescribed restriction(311) and approved by each pin. In order to select slave mode, a first and second switches are turned to 'on' state and 0 switch is turned to 'off' state and signal union is composed. To select the master mode, the second, the first, and the 0 switches are turned to 'off' state and '111' signal union is composed.
