L298N dual H-bridge module
Two bipolar H-bridges for DC motors or one bipolar stepper, 5–46 V motor supply, 2 A per bridge. IN1–IN4 set the outputs (high = output to +12V, low = output to GND), ENA/ENB enable the bridges (jumpers to +5 V fitted: always enabled; remove them for PWM on ENA/ENB). Typical saturation drop 1.35 V (source) + 1.2 V (sink) at 1 A, so a motor gets about 2.5 V less than the supply. Recirculation diodes on the board. Supply the logic with 5 V on the +5V pin.

Simulation model
A behavioural model implements the interface of the chip (registers, protocol, timing) at its pins. The pins are connected to the analog circuit like CMOS pins.
