 ## Board layout
 
+Before we start to assemble your board, we'll take a look at what each section is and what it is for.
+
 ##### CPPM / PPM-SUM
 
 ![640 CPPM](/images/640-cppm.png)
 
+This is the connection that allows you connect a Radio Control (RC) receiver so that you can extend the range of control for your robot.
+
 ##### Servos
 
 ![640 Servos](/images/640-servo.png)
 
+The 640 board has connections for two Servos. They default to being powered by the Raspberry Pi 5v supply, but we can switch them to be powered by the external battery supply if we want to.
+
 ##### Motors
 
 ![640 Motors](/images/640-motors.png)
 
+The 640 board can control 6 independent motors. Each motor has a connection with two pins (or terminals if you are using the screw terminal connections). It doesn't matter which way around you wire your motor, just make sure that you wire them all the same way. If you find that sending a Forward command makes your robot go backwards, then you can switch the wires around.
+
 ##### Power
 
 ![640 Power](/images/640-power.png)
 
+The power connection can accept from 2v all the way up to 11v DC - the power you connect here is isolated from your Raspberry Pi and only goes to the motors. Make sure you match your recommended motor voltage as too much power can damage them, and too little won't make them turn.

 ## Setup your 640
-### Attaching the power
+
-### Attaching a Servo
+### Assemble the parts
-### Attaching a motor
+
-### Attaching an RC receiver
+**IMPORTANT** - if you have an expansion board that you want to add to your 640 board, then you should add that first as it will be a lot easier than adding it after soldering connectors to the board.
