SMAKN V3 for Arduino Motor Controller Shield L298N 2A Motors

*The Arduino Motor controller Shield is based on L298N chipset, which is a high voltage (46V max), high current (2A per phrase) dual full-bridge driver, that can control two motors simultaneously. *l VLC(Voltage Logic Connected?: -L298N motor drive voltage in addition to expanding the logic board described above can be provided after the voltage conversion circuit can also control the board with the Arduino 5V logic voltage to provide a direct connection. VLC is the role of deciding whether to switch the motor-driven expansion of the board and the Arduino 5V logic voltage 5V logic voltage control board connected: When the switch is in the ON position when the connection, when the switch is in the OFF position does not Connection. *VM(Voltage Motor): -VM is the role of the motor voltage selection. When the L298N motor drive expansion board with the Arduino, after connecting, there are two ways to provide power for the motor: Vin pin through the Arduino board (switch in the VIN) and extended through the motor drive board VEX terminal (switch in the VEX .). *In Arduino, L298N motor-driven expansion boards that are hosted by current and voltage are relatively high, so the process used to pay special attention to the connection. Here are some typical circuit connection for your reference in use: Motor voltage is 6 ~ 12V: -In general, Arduino can 6V-12V external power transformer (Arduino on the Vin pin), if you happened to motor voltage within this range, it just can use the external power supply to both the Arduino And motor power. In this case VLO, VLC VM set as: -VLO?OFF?Does not require motor-driven expansion of the voltage conversion circuit board. -VLC?ON?With the Arduino's 5V pin connector for expansion boards to provide motor drive logic voltage. -VM?VIN?The Vin pin with the Arduino connected to the motor drive to provide motor voltage expansion board.
