Gather your Mecanum Kit PCB and all required components listed in the BOM.
It is especially important to follow the BOM exactingly as it tells you where to place the components on the PCB. The fifth column on the BOM is the “parts” column. This column designates which position on the PCB you are to pace the component. For example, if under the parts column you have a resistor labeled r1 you would then find the position marked r1 on the PCB and place the resistor there.
Step 2: Connecting the Motors to the board
Here you can see the junctions labeled M1 → M4. These are the terminals to which you will connect your motor leads.
The junctions are paired together as follows: (M1,M3) and (M2,M4). It is important that for each of these pairs you match which leads from the motors go into the terminals labeled X and Y. If you don’t, the directions from your motors will be out of sync. In the table below I will show you how we wired our motors to the terminals.
With your terminal orientation settled, you can then attach your motors to the mecanum frame. With our Mecanum Kit, the each motor is attached via 2 Allen Screws as seen here:
Take care to ensure that your paired motors (M1,M3) are on one side, and (M2,M4) are on the other. If you don’t your motor directions will be out of sync.
Step 3: Wiring your Mecanum Car to the Builder Base
Once all of your motors are wired and mounted you can connect your PCB to the Builder Base. You can follow along to the diagram and table below to ensure you have the appropriate wiring.
In the above diagram the M4 motor is on top and the M3 motor is on the bottom.
Be careful to make sure that you connect the pcb to 5V and not 3.3V. If you don’t the Mecanum car will be under powered.
