| - | NB! Applied voltage and current are primary dependent of motors which are used and can not exceed the limits of specific motor. These limits should be checked from motor datasheet. Motors provided with the kit are most commonly supplied with the voltage 5-6 V and therefore the power distribution cable is using voltage regulators, limiting the output to 5 or 6 V. | ||

| - | Motor module | + | Motor board is connected with Controller module to the port PE-PB-PD. The power supply to the motors comes from the DCIN connector on the board and runs through voltage regulator, which brings the voltage down to +5V. If DC power is provided to the board and the voltage regulator is working properly, the PWR LED in the bottom right corner of the board will light up. |
