L298n Schaltplan. There is also an onboard 5v regulator so if your supply voltage is up to 12v you can also source 5v from the board. Then connect the power supply as required to points 4 positive and 5 negative gnd.
Connect the a a b and b wires from the stepper motor to the module connections 1 2 13 and 14 respectively. First we ll run through the connections then explain how to control dc motors then a stepper motor. It is a high voltage high current dual full bridge driver de signed to accept standard ttl logic level sand drive inductive loads such as relays solenoids dc and stepping motors.
L298 is a high voltage and high current motor drive chip which receives ttl logic signals.
However with the size of motor that this can support you can have a vehicle large enough to support its physical size. Low saturation voltage overtemperature protection logical 0 input voltage up to 1 5 v high noise immunity description the l298 is an integrated monolithic circuit in a 15 lead multiwatt and powerso20 packages. The l298n h bridge module can be used with motors that have a voltage of between 5 and 35v dc. There is also an onboard 5v regulator so if your supply voltage is up to 12v you can also source 5v from the board.
