The L298N motor drive module (HCROBO0068) contains a dual channel full H-bridge driver. This driver allows up two DC motors to be independently controlled in both forward and reverse directions via a microcontroller such as an Arduino. Alternatively, the module is capable of driving a single 4 input stepper motor. It includes an optional on-board 5V regulator for powering its internal logic circuit so only one supply voltage is required (Vm = 6 to 12V). Screw terminals allow for easy connection of the motor(s) and the power supply.

Specification:

Product code: HCROBO0068
Motor input voltage (Vm): 4 – 24V
Combined motor drive current (max): 2A for 2 minutes / 1A continuous
5V output current (J1 fitted): 100mA
Dimensions: (LxWxH): 43mm x 43mm x 27.5mm



Notes:

When J1 is fitted the input of the on-board 5V regulator is connected to Vm and the 5V terminal becomes an output. If J1 is removed a separate 5V supply connected to the 5V terminal is required to power the digital circuit.

Actual voltage across motor terminals = Vm - ~2.35V

(!) When using the 5V terminal as an output (J1 fitted) DO NOT draw more than 100mA from this terminal.
(!) For Vm voltages > 12V jumper J1 must be removed and a separate 5V supply connected the 5V terminal.

Failure to observe the above conditions will result in permanent damage to the on-board regulator resulting in the motor supply voltage Vm being applied to the 5V terminal.
