The install instructions identify the last 3 pins on the right of the bottom row of block EXP3. I want to be sure I am getting the polarity correct so I checked the schematic which ID’s those pins as 6,4, and 2 from left to right. 2 is shown as +5V. I will connect black to 6, red to 4, and white to 2. Is this correct? Does the order matter ie can they be reversed?
The order matters!
In the assembly instructions you’ll note that we switch the red and white wires on the servo connector. That way
…pin 2 on the board (white wire) will go to the red wire on the servo (5v).
…pin 4 on the board (red wire) will go to the white wire on the servo (signal).
…pin 6 on the board (black wire) will go to the black wire on the servo (gnd).Anything else and the servo won’t move.
