6. Mainboard

In this section, you will add brains of the robot: the RedBot Mainbooard.

Locate the Following:

2x Mainboard Mount (G) 1x RedBot Mainboard (P)
Mainboard mount RedBot Mainboard >

You will also need the full chassis assembly, which contains any additional parts and sensors you attached in previous steps.

Attach the Mainboard Mounts

Snap the two Mainboard Mounts (G) into the vertical slots in the back of the top chassis plate near the large rectangular opening.

Add mainboard mounts

Add the Mainboard

The RedBot Mainboard (P) snaps into the lowest of the notches on the Mainboard Mounts (G). Make sure the power jack is facing the left side of the robot. Push gently and evenly until it snaps into place.

Add the mainboard

NOTE: The other slots in the mainboard mounts can be used to hold the Arduino UNO or the SparkFun RedBoard.

Connecting the Cables

It is time to connect the jumper wires; it is really important that these connections are right.

You can follow along with the pin out tables or scroll down for a diagram. Trace each cable poking through the top chassis plate to make sure you know what it is connected to.

If you have the RedBot Basic Kit, disregard any extra sensors that are missing in your kit. These sensors will be marked with the label (SIK).

Please note: When you have the RedBot upright and the front of the chassis facing away from you, "left" sensors/motors will be on the left side and "right" sensors/motors will be on the right side. Also - the motor wires are intentionally switched for the right motor -- see notes below.
