If you have purchased the SimulConn Master board, you have it in one of these configurations:

• SC-SIMVIMX-MASTER-R1 (raw PCB, no components. Add and solder DIP components yourself)
• SC-SIMVIMX-MASTER-R2 (pre-soldered SMD components. No Arduino! Add and solder connectors and Arduino yourself)
• SC-SIMVIMX-MASTER-R3 (pre-soldered SMD components with embedded Arduino and all connectors

SC-SIMVIMX-MASTER-R2

This version has pre-soldered SMD components. But no Arduino. You will have to acquire an Arduino MEGA 2560 Pro and solder it on yourself.

What you need is:

• MEGA2560PRO : Connects the Arduino.
  Optional, solder a female socket header on the PCB for easy mount/dismount of the Arduino.
• J1-J6 : Connects cable to Extension boards.
  Use 20-pin IDC cable sockets.
• X1 : 12v input power connecter.
  Use a 2-pin screw terminal block connector.
• Stepper/Matrix : Serial connection.
  This connecter holds the serial connection for stepper motor and keyboard matrix.
• Servo : Serial connection.
  This connecter holds the serial connection for Servo motor.
• LCD : Serial connection.
  This connecter holds the serial connection for LCD display.

It is also recommended to mount the Arduino in a female socket header, for easy replacement.

The following components are recommended/required for the Master board.

	Placement	Component
	J1-J8	IDC cable socket 20p	Recommended
	Optional	2.54mm double row female socket header	Recommended
	X1	2 Pin Screw Terminal Block Connector 5.08mm	Recommended
	MEGA2560PRO	RobotDyn Mega 2560 PRO CH340G ATmega2560-16AU	Required
	J9-J11	JST XH 2.54mm 4Pin Socket	Recommended
